Is Nissan hunting for a fuel-efficient diesel engine to stuff between the fenders of its Titan pickup truck? Well, according to Automotive News (sub. req.), that seems to be the case.

Thanks to $15 million in funding from the U.S. Department of Energy, Cummins is developing a 2.8-liter four-cylinder diesel engine aimed at boosting fuel efficiency by 40 percent compared to the current crop of V8 mills in use in light-duty trucks.

Cummins is shooting for a combined rating of 28 miles per gallon, meaning that the diesel-equipped Titan would return more than 30 mpg on the highway without sacrificing power, since Cummins is reportedly targeting 220 horsepower and 380 pound-feet of torque. The prototype engine supposedly cranks out a whopping 350 pound-feet of torque at a mere 1,800 rpm. Development of this fuel-efficient, oil-burning mill should be complete by September 2014.
