Car Porn | Cummins Test Diesel Engine In Nissan Titan | Auto-Moto

Let me start by saying I have been waiting for Nissan to come out with a diesel engine in the U.S. for years!

Cummins is developing a high-efficiency inline-four-cylinder diesel engine with money from the U.S. Department of Energy and in partnership with Nissan for demonstration in the Titan light-duty pickup truck.

Getting 28 mpg combined mileage could mean more than 30 mpg highway, by our estimate, which could help Nissan meet strong new EPA regulations that will raise fleet fuel efficiency standards for light trucks and SUVs to 30 mpg by 2016. The standard for passenger cars is set at 39 mpg by 2016


Cummins refers to the engine by the codename “LA-4” with a 2.8-liter displacement (170 cubic inches). Initial power figures on the engine dyno have the mule test engine producing 350 pounds-feet of torque at around 1,800 rpm. A chart in the presentation shows targeted power levels to be approximately 220 horsepower and 380 pounds-feet.

The engine is likely a derivative of the four-cylinder ISF architecture that Cummins builds overseas, with 2.8-liter and 3.8-liter displacements. The overseas 3.8-liter is rated at 168 horsepower and 443 pounds-feet of torque.
