CUMMINS Engine 【Cummins 6.7L Turbo Diesel (2019)】

For the first time, HD pickup buyers can get an impressive 1000 lb-ft of torque. This high-output (HO) rating is offered exclusively in the RAM 3500 equipped with the Aisin transmission option. The new high-output engine boasts 400 hp and 1000 lb-ft of best-in-class torque.

For RAM 2500 and 3500 (equipped with a 68RFE Auto) HP and torque have increased to 370 hp and 850 lb-ft to provide the right power for these models.

In addition to moving to a higher capability high pressure pump, several critical features were implemented to maintain the proven reliability and durability our customers have come to expect:

• A Compacted Graphite Iron (CGI) material for the block allows us to increase the cylinder pressure capability while reducing the overall weight by almost 60 lbs
• A new cast-iron cylinder head containing high-temperature capable exhaust valves actuated by all-new hydraulic lash adjusters in the block eliminates 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
