Турбодизельный двигатель Cummins объемом 6,7л

Cummins Inc. unveiled its next generation 6.7L turbo diesel engine boasting a first-in-class 1,000 pound-feet of torque. From the introduction of Cummins 5.9L Turbo Diesel powered RAM trucks in 1989, to the latest 6.7L turbo diesel, Cummins has worked with RAM to provide drivers the toughest, most reliable engines on the road. 

The Cummins under the hood of the new 2019 RAM HD pickup is a real showstopper in the RAM Trucks booth at the North American International Auto Show in Detroit, Michigan. This next-generation 6.7L Turbo Diesel provides the power for RAM HD pickups to deliver increased payload and towing while engineered to maintain Cummins proven reliability and dependability.

Setting A New Standard in The Heavy-Duty Pickup Market

The Cummins 6.7L turbo diesel is offered in two variants; standard output 370 horsepower (850 pound-feet of torque) and high output 400 horsepower (record setting 1,000 pound-feet of torque). The high-output (HO) rating is offered exclusively in the RAM 3500 equipped with the Aisin transmission option. The standard-output (SO) at 370 horsepower and 850 pound-feet of torque when matched with the 68RFE transmission option.

“The Cummins name has been synonymous with technological innovation and reliability since 1919,” said Melina Kennedy, General Manager – Cummins Pickup segment.

“We’re proud to introduce our most powerful 6.7-liter engine ever on the year of our centennial – setting the new standard in the heavy-duty pickup market.”

Celebrating A 30 Year Partnership

“In addition to celebrating 100 years of diesel engine production, we are also celebrating 30 years of powering RAM trucks,” stated Srikanth Padmanabhan, Vice President -  Cummins Engine Business. 

"Together, RAM and Cummins have accomplished many milestones and technological advances. From the time the first prototype truck was put together in the 1980s to now, breaking the 1,000 pound-feet barrier together, exemplifies the strength of our partnership."

In the last 30 years, Cummins has produced almost 3 million turbo diesel engines installed in RAM trucks, earning the respect of truck customers everywhere. The blocks are machined and engines are assembled just outside of Cummins' global headquarters in Columbus, Indiana.

Featuring the Latest in Cummins Technology

Base engine improvements made to support the new higher output ratings of the next-generation 6.7L engine include a compacted graphite iron engine block that increases peak cylinder pressure capability, a new cast-iron cylinder head containing high-temperature capable exhaust valves actuated by all-new hydraulic lash adjusters in the block eliminating the need for valvetrain adjustment service intervals. The heart of the engine is a higher strength alloy crankshaft with a 10-bolt crank flange driving newly-designed forged connecting rods and new bearings which transfer power from the low-friction ring wrapped pistons.

A new larger Cummins-Holset variable-geometry turbocharger optimized with heavy duty bearings, and a new compressor-side housing is a key ingredient in the new ratings pumping 33 pounds per square inch (psi) of fresh air into the engine.

The new fuel-delivery system includes a new 29,000 psi (2,000 bar) fuel pump and fuel rail with Cummins Filtration “filter in filter” NanoNet® technology.
