The Cummins B Series is a family of diesel engines produced by American manufacturer Cummins. In production since 1984, the B series engine family is intended for multiple applications on and off-highway, light-duty, and medium-duty. In the automotive industry, it is best known for its use in school buses, public service buses (most commonly the Dennis Dart) in the United Kingdom, and Dodge/Ram pickup trucks.
Since its introduction, three generations of the B series engine have been produced, offered in both inline-four and inline-six configurations in multiple displacements.
General engine features
The B-series features engine bores machined directly into the block (rather than the wet liners used on earlier Cummins engines). It was also set apart by the use of a shallow one-piece head, requiring closer tolerances than in other Cummins products. The engine was first manufactured in Rocky Mount, North Carolina, and other plants were later added in Mexico, Turkey, and Darlington, UK.
Every Cummins powered Dodge Pickup (since initial production in 1989) has come equipped with a turbocharger. It uses a gear-drive camshaft for extra reliability. Also specified is a deep-skirt engine block and extra-strong connecting rods. A Holsetturbocharger is used. The original B Series was updated with 24 valves and an electronic engine management system to become the ISB in 1998.
|Name||Displacement||Cylinders||Fuel||Years of production|
|ISB||4.0L or 5.9L||4 or 6|
|B Gas Plus||Natural Gas|
The 4.0L/4BT Cummins is an engine in the same family as the 5,883 cc (5.9 L; 359.0 cu in) Cummins diesels. The 4.0L/4B is an inline four-cylinder naturally aspirated or turbodiesel that was popular for many step van applications, including bread vans and other commercial vehicles. Additionally it has seen broad usage in agricultural equipment. It has also gained popularity as an engine swap into smaller trucks. The lowest powered 4B produces 53 hp (40 kW).
|5.9-liter B series Cummins |
The 5,883 cc (5.9 L; 359.0 cu in) 6BT, also known as the "12-valve" Cummins was the first member of the "B" engine family to be used in a light truck vehicle. The 6BT used Bosch fuel systems, injector, and VE rotary pump and P7100 inline injection pumps. Some early 6BTs were supplied with CAV rotary pumps instead, before the Bosch system became the sole standard. This engine started life in 1984 designed as an agricultural engine, for use in Case agricultural equipment.[full citation needed] After 1989, the 6BT engine was used in light duty, medium duty and select heavy duty trucks and buses. The 6BT engine has recently become very popular for use in repowering various vehicles, in the UK they have proven very popular in the Land Rover community, commonly known as the ‘good’ conversion.
Appearing in the 1989–1998 Dodge Ram pickup truck, it became a popular alternative to the large gasoline V8 engines normally used in full-size pickup trucks, since it produced the torque at low engine speeds, and significantly better fuel mileage. During that time, the Dodge Ram was the only diesel pickup that did not rely on glowplugs for cold weather starting.
|5.9-liter ISB Cummins |
The 5.9 L; 359.0 cu in (5,883 cc) ISB (Interact System B) is one of the largeststraight-six engines used for light truck vehicles and school buses, and the improved high output 600 version was on the Ward's 10 Best Engines list for 2004.
One unusual feature of the ISB is that it is a multi-valvepushrod engine design, with 4 valves per cylinder (popularly referred to as the "24-valve" Cummins). The engine displaces 5.9 L; 359.0 cu in (5,883 cc), with a 102 mm × 120 mm (4.02 in × 4.72 in) cylinder bore and piston stroke. A turbocharger is used to increase the output in the high-compression (17.2:1 in recent versions) diesel. It is an all-iron engine with forged steel connecting rods, an assembled camshaft, and a cast aluminum intake manifold. The engine is produced in Columbus, Indiana.
The ISB uses electronically controlled Bosch fuel systems, unlike the 6BT systems which were mechanical. Early ISB engines utilize Bosch injectors and a Bosch VP44 high pressure pump. Later ISB designs have common rail fuel injection, Bosch injectors, and a Bosch CP3 high pressure pump.
The 5.9 L; 359.0 cu in (5,883 cc) QSB (Quantum System B) is the off-road, heavy duty version of the ISB. Typically used in marine, agricultural, and construction applications, these engines share many of the same parts as the ISB and utilize the same Bosch fuel system.
Dodge Ram ISB
Midway through model year 1998, the Dodge Ram switched from the 6BT to the ISB to meet updated emissions requirements. Like other ISB's, these engines started out using the Bosch VP44 rotary injection pump. The VP44 setup meant that timing and fuel could be precisely controlled, which led to cleaner emissions. However, VP44 failure rates were higher than the older P7100 injection pump. The compression ratio in these engines was 17.2:1. The 1998–2000 ISB was rated at 215 hp (160 kW; 218 PS) and 420 lb⋅ft (569 N⋅m) when equipped with the 47REautomatic transmission. The 1998–2000 ISB was rated at 235 hp (175 kW; 238 PS) and 460 lb⋅ft (624 N⋅m) when equipped with a manual transmission. For the 2001-2002 years, a standard output and a high output ISB Cummins engine were offered. The standard output, which was the same as the previous engines was rated to 235 hp (175 kW; 238 PS) and 460 lb⋅ft (624 N⋅m) when equipped with either a manual transmission or automatic. The high output ISB was rated at 245 hp (183 kW; 248 PS) and 505 lb⋅ft (685 N⋅m), with only a NV5600 six-speed manual transmission available. The high output engine was different in a few ways from the standard output engine; it had higher compression (17.3:1), powdered metal valve seat inserts, a larger flywheel, the Bosch fuel system was reworked to allow higher fuel flows, and fuel-injection timing was altered.
Dodge Ram ISB CR
For the 2003 model year, the Cummins was introduced with Bosch high pressure common rail fuel injection, again increasing power output. On automatic equipped vehicles, the 47RE was upgraded internally to increase durability and torque capacity, now known as the 48RE. The 2003 rating for the Dodge truck was released at 305 hp (227 kW; 309 PS) and 555 lb⋅ft (752 N⋅m). Midway through the 2004 model year, the Cummins 600 was introduced, producing 325 hp (242 kW; 330 PS) at 2,900 rpm and 600 lb⋅ft (813 N⋅m) at 1,600 rpm. This engine was noticeably quieter than the previous engines.[non-primary source needed]
|6.7-liter ISB Cummins |
The B6.7 is the latest version of the B Series. It is currently the largest straight-six engine produced for a light duty truck or school bus. It produces 350 hp (261 kW; 355 PS) and 650 lb⋅ft (881 N⋅m) in the 2007.5 and newer Dodge 2500/3500 pickup trucks with the Chrysler-built six-speed 68RFEautomatic transmission built at the Kokomo Transmission plant in Kokomo, Indiana. Engine torque is slightly reduced with the Mercedes G56 6-speed manual transmission at 350 hp (261 kW; 355 PS) and 610 lb⋅ft (827 N⋅m). The 2007 and newer 3500 Cab & Chassis trucks only get the 305 hp (227 kW; 309 PS) and 610 lb⋅ft (827 N⋅m) version of the B6.7, whether it has the Aisin AS68RC or the Mercedes G56 6-speed manual transmission. As for the 2008 4500/5500 medium duty Chassis Cabs or the Sterling Bullet Trucks, they receive the 350 hp (261 kW; 355 PS) and 610 lb⋅ft (827 N⋅m) version of the B6.7, whether it has the Aisin AS68RC or the Mercedes G56 6-speed manual transmission. Late model 2011 Ram trucks produce 350 hp (261 kW; 355 PS) and 800 lb⋅ft (1,085 N⋅m), with the exhaust brake rating boosted from 150 hp (112 kW; 152 PS) to 222 hp (166 kW; 225 PS).
For 2020 this engine has been updated to produce 400hp and 1000 ft-lb torque.
It is also used in the Blue Bird Vision, Thomas Saf-T-Liner C2, and IC CE school buses
Changes over the 5.9
There are many changes over the previous B5.9 for the Dodge truck, the most obvious being the larger displacement. The B6.7 had an increase of cylinder bore and piston stroke to 107 mm × 124 mm (4.21 in × 4.88 in), respectively, thereby giving a displacement of 6.7 L; 408.2 cu in (6,690 cc).[full citation needed]
With the 6.7 L Cummins Engine came the introduction of the Variable Geometry Turbocharger (VGT). The VGT Turbocharger was introduced to reduce turbo lag by adjusting the vanes by sliding a steel ring in the exhaust housing dependent on engine RPM creating more or less pressure inside the exhaust housing and controlling the speed of the turbocharger. It also works as an integrated exhaust brake system and is all controlled by an electronic actuator on the turbocharger. This VGT system has been an extremely common issue with the 6.7L Cummins platform and is typically diagnosed by the loss of the trucks exhaust brake.
The two-thirds version of the ISB is the 4-cylinder 4.5-liter at 185 hp (138 kW), used in the New Routemaster, a serieshybrid diesel-electric doubledecker bus in London.
Mechanical Injection with Mechanical Timing
In the earlier models of the Cummins B Series Engine, it was almost entirely mechanical including its fuel system. The fuel pump used in these engines was the P7100 injection pump, this pump is driven off the camshaft gear and drives it own internal camshaft to inject fuel to the individual injectors. This pump itself was one of the most popular options for fueling for the B Series Engines because of this simplistic design and how reliable it was. The P7100 injection pump also allows for large amounts of fuel to be delivered into the system with simple tweaking to the system to allow for larger injection events.
Mechanical Injection with Electronic Timing
In the later models of B Series Engine, the fuel system was switched from mechanical injection and timing to mechanical injection with electronic timing. This was all thanks to Bosch's new VP44 injection pump. The VP44 injection pump is driven at half the camshaft speed and produces fuel pressure at about 4,500 psi to pop the vertically centered injectors in the engine. These injection pumps need to have constant fuel pressure behind them of at least 10psi at all times to maintain the priming of the system. If you run these pumps dry it can cause your pump to fail quickly. The VP44 injection pumps were the first pumps placed in the Cummins engine to have an FPCM. FPCM stands for the fuel pressure control module, and this is responsible for maintaining and controlling the fuel pressure of the system. However, even though this new technology to control fuel pressure was convenient, it had a major downfall. The problem was that they were unable to be serviced without replacing the entire fuel pump. Another important piece of the puzzle that is responsible for the longevity and functionality of the VP44 was the fuel transfer pump mounted on the side of the block next to the ECM. This electronically driven vane pump is what supplies that minimum of 10psi to the injection pump so it maintains constant fuel pressure as well, as cools itself, and lubricates itself. 
Mechanical Injection with Electronic Timing and Common Rail Pressurization
The most recent method of fuel injection that is still in use today is called common rail injection. Common rail injection is a completely revolutionary design to fuel injection since a fuel pump is now used to pressurize a rail and then from there sends the fuel to each injector. A major benefit of switching over to this fueling system was how it allowed for much less leakage into the cylinders pre and post ignition. This is all possible since this fuel system operated upwards of 2600 bar so they are able to set spring tension higher in each injector to allow for more precise fuel injection and timing. Another benefit of using common rail injection and having one rail pressurized compared to pressurizing each individual injector is that it is more reliable since it allows for more consistent fuel delivery to each injector.

Cummins Engine History: American Gumption
Clessie Cummins and Race Crew - 1934 Cummins History Timeline
Like most success stories, the history of Cummins Engine Company, started from humble beginnings and a perseverance to try something new. The early days of Cummins Engines were not like what we have all come to expect from the power generation giant of today. In fact the company almost folded a few years after its start.
Cummins Inc. was found in 1919 by Clessie Cummins in Columbus, Indiana. Clessie Cummins was no business genius; just a man with a vision and gumption to put in some hard work which would later be synonymous with his diesel engines. Clessie was born December 27, 1888 in rural Indiana, had no formal education beyond the eighth grade and had to leave to school to work on the family farm. Clessie was always very mechanical inclined and as legend has it, at 11 years old, he built his own steam engine from molten cast iron he poured into wooden molds. The steam engine worked and was used to pump water on the family farm.
Young Clessie knew that farming wasn’t something he wanted to do with his life and sought out on his own. All thing mechanical fascinated him. Not only did Clessie have a passion for all thing mechanical but also grasped the engineering and creative principals needed to become a master mechanic. Clessie took odd jobs around Indiana until landing a job as a mechanic with automotive maker Nordyke and Marmon(Marmon Motor Company) which made some of the first luxury cars in America before being bought out by Allis-Chalmers in 1926.
Through a friend at Nordyke and Marmon, Clessie was hired by race car driver Ray Harroun who entered the now famous Marmon-Wasp in the first ever Indianapolis 500, also known as the brickyard. It was nicknamed “The Brickyard” because the 2.5 mile track was made entirely out of brick. Clessie was part of the pit-crew and made many suggestions to improve the speed and handling of the car. Clessie was part of history; the first ever Indianapolis 500, in 1911, was won by Ray Harroun and team running the 1911 Marmon Wasp. The car had the first ever rear-view mirror in history which helped win the race. Clessie would take this sense of accomplishment with him the rest of his life and spurred his love of racing. Cummins engine history is steeped in racing and would play a part in growing the company.
First Cummins Hvid Engine - 1919 Cummins History Timeline
It was during his time with Ray Harroun and The Marmon Motor Company that Clessie caught the eye of William Irwin. Irwin was the financial backer of Harroun’s Race Team and venture capitalist in the Columbus, Indiana area. Irwin noticed Clessie had a knack for everything mechanical and thought of ways to help empower the young Cummins. Clessie made money on the side by working as a chauffeur and mechanic for Irwin. Clessie impressed Irwin by building a gasoline engine prototype in Irwin’s garage from scratch in 1915. Irwin and Clessie worked on mechanical projects in the early 1900s eventually deciding to build engines themselves for local farmers. The friendship between Clessie and Irwin would go on to last a lifetime.
Irwin and Cummins were first introduced to diesel engines in 1918 when they witnessed an imported Dutch engine from manufacturer R.M. Hvid Company on tour in the United States. Cummins and Irwin were impressed with the new technology (only invented 19 years earlier by Rudolf Diesel) and sought a way to distribute Hvid engines to customers in America. After traveling to the Netherlands, Irwin and Cummins were awarded a license to sell Hvid engines in the United States. It also helped that Irwin was the National Director of the United States Department of Commerce and helped facilitate the deal.
Winning Marmon-Wasp Race Car - 1911 Cummins Engine History Timeline
In 1919, with $10,000 from Irwin, Cummins Engine Company was formed in Columbus, Indiana. Cummins produced a re-designed 8 hp Hvid engine with his own improvements. The company made enough money to cover the costs of operations. By 1921 Cummins had successfully secured 2 out of 33 submitted patents for improved fuel efficiency and manifold technology for the licensed Hvid engines.
Cummins Factory - Cummins Engine History Timeline
By 1924 Cummins applied his new designs to his own Model F engine which was entirely designed on his own accord, thus ending the partnership with R.M. Hvid Company. Irwin backed the Model F production with $100,000.
Cummins then successfully negotiated with Sears Roebuck and Company to sell their engines in the famous Sears’ Catalog. Initially, business was booming for the new company. However, the Sears’ Catalog advertising venture became a disaster for Cummins. Many farmers took advantage of a loophole provided by Sears’ return policy. They purchased the engines, used them for a single season, and then returned them for a refund. Engines were run at full load without regard for safety or maintenance. Irwin, who as Cummins’ financial backer, was not happy with the durability of the diesel engines the company was putting out and encouraged Cummins to improve the design and reliability of the diesel engines. It is said that the first limited engine warranty was born from these early trials and tribulations to protect manufactures from reckless consumers.
Cross Country Promotional Trips
Cummins Diesel Powered Packard - 1930 Cummins Engine History Timeline
Cummins realized that industrial application engines were not the best route for the growing business considering the wear farmers did to their engines. Dirt, mud and foliage particulate matter often clogged the engines, which were at the time often exposed to the elements on makeshift plows. Cummins was convinced the future of diesel engines was in over-the-road trucks and cars. To demonstrate the efficiency of diesel to the general public he installed one of his diesel engines in his 1926 Packard and drove from Indiana to New York. The event was not publicized but Cummins had in his mind to present the car at the 1930 New York Auto Show at the end of his journey. The car drove 800+ miles having only used a mere 30 gallons of fuel. The diesel engine averaged 26 miles per gallon which is an amazing feat which is still quite impressive today.
When Cummins got to New York he was turned away from the auto show as he was not a registered exhibitor. However, Cummins was determined to show the public his invention and he once again tried to display his car at the nearby Atlantic City Auto Show only to be turned away. Cummins had a brilliant idea to rent the empty space across the street from the convention center. His perseverance paid off and it turned out his exhibit ended up being more of a major attraction than most of the cars at the actual auto show.
Early Cummins Model F Engine - 1930s Cummins Engine History Timeline
Cummins’ first taste as a “showman” turned out to be very successful. Even though the country was in the midst of a Great Depression, Cummins had already decided to go ahead and market a strictly over the road diesel engine for the consumer market prior to 1929. The orders from his Model U engines poured in after his first auto show appearance. However, Cummins had not anticipated the demand. The engine guzzled oil and he had made no provisions for an assembly line process in his factory back in Indiana. This first consumer diesel engine would be known as the Model U. Model U Cummins engine history is a bit blurry today but there are still a few left in the world which actually still work. It was Cummins’ goal to get his engine mass produced by one of the budding automakers in America. First he had to prove his diesel engine was every bit economical and could compete with gasoline engines which were in the majority of automobiles. Cummins sought to do this with a “PT Barnum” style of exhibitions throughout the country. A lot of interest in diesel dried up when the stock market crashed in 1929 but Irwin continue to support the company to stave off bankruptcy.
Tough Times: Great Depression Era
Cummins and Team Truck Exhibition - 1931 Cummins History Timeline
Before the Stock Market Crash of 1929 Cummins had hoped that his engines would be a luxury items installed in prestigious cars. In fact, many of his engines were used in luxury yachts and marine applications. However, after the depression set in all of that luxury market disappeared. A new market though appeared to be the right fit for Cummins’ Engines: Over The Road Trucks. William Irwin just so happened to own a controlling interest in Purity Supreme Supermarkets in California. Cummins convinced Irwin to install his diesel engines in his fleet of trucks used to transport food goods from the warehouses to the stores. It was the perfect fit for the two companies. The diesel engines performed better on the steep mountain roads, were less prone to maintenance issues than gasoline engines are were more fuel efficient. The word spread about the benefits of using diesel engines in heavy duty trucks and the over-the-road truck industry was born. Cummins would become synonymous with truck engines from that point on. Truck engines would keep the company going but Cummins still had his sights for something bigger. He envisioned diesel engines in every car in America. That dream would never fully take off; it took a while but the majority of Cummins' customer base would be involved in the trucking industry vs. the direct to consumer automobile market.
Cummins Test Bus - 1930s Cummins Engine History Timeline
Cummins was determined to keep moving forward and in 1930 he staged a smaller road trip to Daytona Beach, Florida to meet up with famed British racer Kaye Don who was attempting to set a new land speed record. Cummins made the 1,275 mile trip only using about $2.30 in fuel. He got 40 miles per gallon with a top speed of 80.5 mph and had all of the eye witnesses and receipts to prove it too. The reporters were amazed with the efficiency of the engine and the wire reports went out all over the world. Cummins was gaining traction despite tough economic times.
The second great exhibition Cummins staged happened in 1931 where he drove from New York to Los Angeles. Unlike the first road trip Cummins embarked upon a year earlier, this one was high publicized. The journey was made in a Marion Truck outfitted with a Model U engine. The trip would cover over 3,000 miles over a network of dirt roads and poorly paved thoroughfares. Cummins managed to complete the journey in only 97 hours; more than 25 years before the construction of the national interstate highway system instituted by President Eisenhower.
The success of the second exhibition led to some notoriety nationally for Cummins. He followed his success with another cross country trip however this time with a bus. That journey from, New York to Los Angeles, took 91 hours and achieved top speeds of 60 to 65 mph. The speed of this cross country journey proved to be faster than many of the passenger train routes of the day. Cummins saw the future of the automobile in America and put all of his eggs into the over-the-road basket. He envisioned a day when all cars would be run with diesel engines.
First Racing Success at Indianapolis Motor Speedway
Cummins Early Race Car Prototype - 1930s Cummins History Timeline
Cummins realized that speed tests and more importantly the sport of racing was becoming big business. He wanted the inside track on gaining access to the racing demographic. In 1931 Cummins successfully logged 13,535 miles of track time at Indianapolis Motor Speedway in test runs of his Model U Marine Engine. These tests further cemented Cummins as a notable name in the automotive community, so much so that on the advice of fellow enthusiasts Cummins decided to race himself. Cummins entered a diesel-powered Model A Duesenberg in the 1931 Indianapolis 500 and finished 13th. The most remarkable feat is that car finished the entire race without a single pit stop and only used 1 tank of fuel and reached an outstanding 86 mph!
Cummins Diesel Race Car - 1950 Cummins Engine History Timeline
Cummins hoped that his racing and trial runs would help him land a major automaker however he could never put a deal together with longtime muse, Packard Motor Company. In 1935, for his third cross country trip, Cummins decided to seek out other automotive partners. Cummins sought out to make diesel engines a luxury item despite market conditions. In turn he sought out partners that produced higher end luxury automobiles. Auburn Motor Company, like Packard Motor Company, produced higher end luxury touring cars. Cummins swapped in a new lighter weight six-cylinder diesel engine, dubbed the Model H, into an Auburn 851 Sedan. The 1935 trip proved to be the best one yet as the car reached top speeds of 90 mph and reached an impressive 40 mpg. Cummins thought he was on the right track with Auburn however the company went out of business the following year.
It is important to note that a this time in the company history that, Clessie Cummins, in some respects, had tunnel vision. He would not give up his dream of trying to promote his engine for the commercial automobile market. For 20+ years Cummins would pursue the direct to consumer market. If the company had one failure it would be not recognizing what they were good at (truck engines) and focus solely on that. market. Still Cummins would push on with more and more test runs and races at Indianapolis Motor Speedway.
Indianapolis 500 Poster - 1952 Cummins Engine History Timeline
In 1934 Cummins would return to the Indianapolis 500 with two new diesel cars. The first car was a two-stroke engine and the other a revolutionary new four-stroke engine. Both engines were turbocharged with Roots-Type superchargers that were blazing fast. Although the two-stroke engine finished ahead of the four-stroke engine it was smoking horribly from overheating. In fact the engine got so hot that the pistons melted into the block. It was this event that spurred Cummins to abandon two-stroke engines and solely make four-stroke engines. With greater speed came greater pressure on the pistons which facilitated the need to have four cycles. Four cycle engines consist of four separate parts to generate power: intake, compression, power creation and exhaust. World War I flying Ace Eddie Rickenbacker owned the Indianapolis Motor Speedway at the time, and was eager to hold exhibitions and speed tests with Cummins to keep his track afloat during the Great Depression. Cummins' tests grew great crowds!
The Cummins Corporation would go on to be a staple in the Indianapolis 500 for decades to come however a first place finish would never be in the cards for the company. The company pulled out all of the stops in the early 1950s hoping to produce a winning car. In the 1950 Indianapolis 500 Cummins entered the race with its “Green Hornet” car powered by a Model JS engine producing 340 hp however the car finished 29th. The closest Cummins got to the elusive first place finish was in 1952 Indianapolis 500 when the car took a first place qualifying position. However, during the race the car fell back and finished 27th. A post race inspection of the car revealed the turbocharger air inlet was clogged with rubber tire particles from the track. It was found that albeit diesel engines could obtain great speeds (over 100 mph) they were slow to ramp up and could not compete with gasoline engines out of the starting gate. Competing in racing would always mean the team would have to win from a come from behind position. Cummins experimented with superchargers and later turbochargers for that initial boost of speed, later acquiring Holset Turbochargers in 1973 but could never figure out how to have a 1st place car at Indy. Discouraged, Cummins never entered another car at the Indianapolis 500 and in-fact 1952 was the last year a diesel-powered race car ever competed at the event.
A New Dawn: Road to Economic Recovery
The company continued to grow as the country recovered from the effects of the Great Depression. William Irwin was convinced that Europe was an untapped market and was in better shape than the US during the depression era. Cummins and Irwin toured all around Italy, France and Switzerland first starting in 1932 but making trips well into the late 1930s. The word spread and orders were placed back in Indiana for the European market. Like the US, Europe mainly was interested in diesel engines for semi-trucks. 1932 was really the tipping point for Cummins truck engines. That same year they landed a contract with large-truck maker Kenworth for the option of having a diesel engine built into the truck. The truck engine was a 4 cylinder, 100 hp, HA4 model. Subsequent events would also showcase the long distance capabilities of semi-truck engines.
All of this publicity was helping to push the company into the public conscience. The financial backers were equally impressed with the company’s growth. In 1934, William Irwin’s great nephew, J. Irwin Miller would become the general manager of the company and continue to run it for over 40 years. Under J. Irwin Miller’s leadership the company would turn its first profit in 1937 and in 1940 was the first engine manufacturer to offer a 100,000 mile warranty. The hardship of the earlier years would finally be erased as the United States entered World War II. Cummins produced mass quantities of engines for the US Government for every year of the war. Every engine produced was installed in trucks and sent to both the European and Pacific Theaters. The company obtained many military and civil contracts, expanded its facilities, increased it labor force tremendously and offered a full range of new engines. All major trucking companies used Cummins engines because of their reliability, torque ratio, horsepower and the excellent fuel mileage.
Cummins Military Trucks in WWII - Cummins Engine History Timeline
After World War II Clessie Cummins decided not to go back to racing or promoting his engines in automobiles. Clessie had gone into semi-retirment leaving his brother, Donald Cummins, in a position to operate the company with General Manager J. Irwin Miller. The last big project Clessie worked on with Cummins was the ramp up of contracts required for the Korean War from 1950-1953. The 1950s and beyond would become a boom time for Cummins as the National Interstate Highway System was built all across the country. Newly paved roads opened up all kinds of new opportunities for over-the-road shipping. All of that transport meant more trucks equipped with Cummins Diesel engines.
The Golden Era of Clessie Cummins
Clessie Cummins in Workshop Shortly Before Death - 1960s
In 1955, at age 67, Clessie Cummins officially retired from the company that bears his name. He stepped down as Chairman of the Board and later formed Cummins Enterprises Inc. to tinker with designs of his own and modify patents he held. It is speculated that Clessie was forced to step down and that he never interfered with his “old” company ever again. Later he moved to California where he founded Allison Aircraft Engine Company.
The last great invention of Clessie Cummins would come towards the end of his life. On one of Clessie’s trips across the country he came across a steep grade near Cajon Pass in Barstow, California. Clessie was behind the wheel when the brakes failed on the truck. Clessie downshifted to slow down the vehicle only to his surprise to see a train speeding by at the bottom of the hill. Luckily for Clessie the train cleared the crossing only seconds before the truck ran over the tracks at 35 mph. It was this life changing experience that spurred an idea in Clessie.
Clessie began experimenting in the mid 1950s with way to slow down a truck in motion. Clessie Cummins Sr. and Clessie Lyle Cummins (Junior) found the answer in 1954. They developed an engine brake which consisted of a valve lifter that slightly opened the exhaust valves to release compression and prevent the fuel from igniting. The system was designed so that the driver could use a switch mounted in the cab to select the number of cylinder they wanted to release compression from.
Cummins Executives with Clessie Cummins - 1950s Cummins History Timeline
Clessie shopped the idea around to all of the major truck manufacturers but found no takers for his new technology. That was until Clessie’s nephew introduced him to the Jacobs Chuck Company who was famous for creating a three-bit rotating drill chuck. They backed the new invention and helped to sell the idea. By the late 1950s many big rigs were equipped with “Jake Brakes”. This was an emergency life saving device that is still in use today in big rigs and diesel pickups.
Clessie passed away at on August 17, 1968 at his home in California at the age of 80. It was said that he was even working on a concept engine in his basement days before his death. Clessie’s legacy is steep in history and lure. He wrote a short autobiography before his death but it is hard to find these days. His son Clessie Lyle Cummins’ biography of his dad is more well known and complete. Cummins Engine Company continued to grow long after Clessie’s death.
Cummins Engine Company Today and Beyond
Dodge Rams with Cummins Engines
In 1989 Cummins Engines signed a contract with Dodge Truck Division to supply diesel engines for its Ram line of light duty pickups. General Motors had diesel engines in pickups since 1978 and Ford since 1983. Dodge had already tried Perkins and Mitsubishi engines in its pickups but were never massed produced. This contract with Dodge proved to be one of the most lucrative contracts for Cummins. The deal with Dodge was, in many ways, fulfilling Clessie’s dream of supplying his engines to a major automotive manufacture; something he was never able to do in life. In 2006 the 1.5 millionth diesel engine for the Dodge Ram came off the line in Columbus, Indiana.
Modern Day Cummins Plant - 2015 Cummins Engine History
Cummins is now the largest over-the-road truck engine manufacturer in the world with 37.5% market share of the heavy duty diesel industry. Cummins is truly a global company. The first foreign manufacturing plant opened in Shotts, Scotland in 1956. Today Cummins has over 5,000 facilities in 197 countries. In fact, in 2015 more than half of the 19 billion in sales accounted for have come from outside of the United States.
Today Cummins is more than just an engine manufacturer but a multifaceted corporation concerned with engines, power generation, parts and components, used and remanufactured diesel engines and distribution. The company continues to innovate with newer more clean technologies to meet consumer demand as well as EPA regulations. In fact Cummins has come out with the first 90% NOx reduction engine ahead of the 2023 – 2031 upcoming EPA Tier regulations.
Cummins Market Share Graph - 2015 Cummins History Timeline
Cummins Engines Company is truly a story of innovation and a never get up spirit. Through trials and tribulations along the way the company has survived on the same principals as Clessie installed in the company so many years ago: honesty, integrity and a relentless passion to keep innovating. It will be interesting to see how Cummins continues to dominate in the years to come.

Cummins Inc. is an American multinational corporation that designs, manufactures, and distributes engines, filtration, and power generation products. Cummins also services engines and related equipment, including fuel systems, controls, air handling, filtration, emission control, electrical power generation systems, and trucks.
Headquartered in Columbus, Indiana, Cummins sells in approximately 190 countries and territories through a network of more than 600 company-owned and independent distributors and approximately 7,200 dealers. Cummins reported net income of $2.19 billion on sales of $23.77 billion in 2018.
The Cummins Engine Company was founded in Columbus, Indiana on February 3, 1919 by J Irwin Miller, William G. Irwin, and Clessie Cummins, a local mechanic. It focused on developing the diesel engine invented 20 years earlier, but in spite of several well publicized endurance trials, it was not until 1933 that their Model H, used in small railroad switchers, proved successful. The Cummins N Series engines became the industry leader in the post-World War II road building boom in the United States, with more than half the heavy duty truck market using a Cummins engine from 1952 to 1959. In the 1960s, the company opened an assembly plant in Shotts, Scotland (closed in 1996). By 2013, Cummins had operations in 197 countries and territories.
Cummins Engine Business
Cummins Engine Business Unit consists of Aftermarket support, Mid-Range, Heavy-Duty, and High-Power Engines. Cummins manufactures and markets a complete line of diesel and natural gas-powered engines for on-highway and off-highway use. Its markets include heavy-and medium-duty truck, bus, recreational vehicle (RV), light-duty automotive and a number of industrial uses including, construction, mining, marine, oil and gas, railroad and military equipment.
For the general public, the most visible Cummins product may be the 5.9-liter in-line six-cylinder engine used in the Dodge Ram light duty pickups starting in 1988.5. In 2007.5, a 6.7-liter version of the Cummins straight six engine became optional on the RAM pickup. In 2008, Cummins was a named defendant in a class action suit related to 1998-2001 model year Chrysler Dodge Ram trucks, model 2500 or 3500, originally equipped with a Cummins ISB 5.9 liter diesel engine built using a pattern 53 Block. The case has been settled, but some qualified Chrysler owners may receive $500 for repairs to the block, which was alleged to crack and create a coolant leak.
In April 2013, Cummins utilized technology developed by Westport Innovations to begin shipping large natural gas fueled engines to truck manufacturers in the United States as trucking companies began converting portions of their fleets to natural gas and the natural gas distribution network in the United States began to expand.
Cummins has a technical centre in Darlington, England, where it develops products for the European, Middle Eastern, and Asian markets.

Cummins Turbo Technologies
The Holset Engineering Co. was a British company that produced turbochargers, primarily for diesel and heavy duty applications.
In 1973 the company was purchased by Cummins after briefly being owned by the Hanson Trust. Holset now operates facilities in China, India, Brazil, the Netherlands, the United Kingdom, and the United States.
In 2006, the division officially changed its name to Cummins Turbo Technologies to be identified more closely with its parent company. The turbocharger products still use the Holset brand name.
Cummins Power Systems
In 1986 Cummins began acquisition of Onan and completed it in 1992. Since then, Onan has evolved[buzzword] into Cummins Power Generation (now Cummins Power Systems), a wholly invested division of Cummins. The Onan name continues to be used for modern versions of their traditional engine-driven generators for RV, marine, commercial mobility, home standby, and portable use.
Cummins Inc. (NYSE: CMI) announced that it will be unifying[buzzword] its brand strategy[buzzword] across its Power Systems business segment, which provides high-speed engines from 760 – 4400 hp and power generation equipment from 2–3,500 kW, including standby and prime power gen sets, alternators, switchgear and other components. Currently the portfolio features the Cummins, Cummins Power Generation and Cummins Onan brands. With immediate effect, the branding will be consolidated under the Cummins brand. The Cummins Power Generation and Cummins Onan brands will be retired and the Onan name synonymous[buzzword] with mobile gensets, will be repositioned[buzzword] as a generator product line under the newly unified Cummins brand in the RV market.
Cummins Inc. will also be permanently changing all “Fun Roads” branding to Cummins RV moving forward as well and the Fun Roads brand will also be retired. As Onan will now be repositioned as a RV product line, with the new rv.cummins.com website and social media platforms serving as tools for RVers across the country to find relevant information like product specs and our sales and service locator.
“Looking to unify Cummins into one cohesive, unified brand, we decided that consolidating both products (engines and generators) into the Cummins RV family only strengthens the brand and more uniformly speaks to our manufacturers and consumers,” said Jodie Wilson. “The brand changing will not affect product or service offerings, but will help us to continue on our promise of delivering dependability across the globe.”
Rebranding took place globally on all marketing activities, as product branding changed across all manufacturing plants beginning July 2017.
Cummins Emission Solutions
Exhaust and emissions after-treatment company Nelson Industries was purchased in 1999, due to the increasing importance of exhaust after-treatment systems for meeting future emissions standards. The division officially changed its name to Cummins Emission Solutions, in order to be identified more closely with their parent company.
Cummins has some joint ventures with Chinese manufacturer, such as Dongfeng Cummins, a joint venture with Dongfeng Automobile Company, as well as Guangxi Cummins Industrial Power with LiuGong.
Other entities were Cummins Beijing, Chongqing Cummins Engine, Xi’an Cummins Engine, Wuxi Newage Alternators, Xiangfan Fleetguard, Wuxi Cummins Turbo Technologies.
Cummins began its India operations on 17 February 1962 in a joint venture with the Kirloskar Group. The ownership structure of the joint venture was divided as follows:
In 1996 Cummins Inc. bought Kirloskar shares. Now its Cummins Inc. subsidiary. As of 2013, the Cummins group had revenues of over $1.5 billion, 20 factories and 9000 employees in India.
Cummins does a significant part of its R&D in India at the Cummins Research and Technology centre that was set up in 2003. Also, Cummins is building an advanced technical centre in Pune which will house over 2000 engineers.

Clean Air Act violation
In 1998, the EPA announced fines totaling $83.4 million against Cummins and six other diesel engine manufacturers, the largest fine to date. The fines came after manufacturers evaded testing by deliberately deactivating emissions controls during highway driving, in order to give the appearance of being in full regulatory compliance during standard laboratory testing. The manufacturers also agreed to spend more than $1 billion to correct the problem. The trucks used engine ECU software to engage pollution controls during the 20-minute lab tests to verify compliance with the Clean Air Act, but then quietly disabled the emissions controls during normal highway cruising, thereby emitting up to three times the maximum allowed NOx pollution.

It was getting hot. It was a time when young girls did not yet wear ugly unisex, but preferred skirts and dresses. Somehow developed by themselves This summer my wife and I and a group of two married couples were relaxing on the lake in tents. The first evening I was very pleased, when twilight came, taking cognac on their breasts, our ladies rushed merrily and amicably to swim, throwing off.
All their clothes.
