Chrysler, US partner on diesel-gas engine

by David Zatz on

While other manufacturers have been experimenting with diesel-like engines that use gasoline under extremely high compression, Chrysler has partnered with the U.S. Department of Energy to experiment with a combination of gasoline and diesel fuel in the same engine.

The test engine is a turbocharged 2.4 liter, presumably a “World Engine,” expected to have over 250 horsepower and 260 lb-ft of torque (the engine actually made more power in SRT4 trim, but with a gas mileage penalty); the target gas mileage in a minivan is over 20 mpg city, and over 30 mpg highway, roughly a 25% increase over the 4-liter V6 used in 2010. Two separate fuel tanks would be used, one for gasoline and one for diesel; the engine has two fuel injectors (with direct injection) for gasoline, and one for diesel, along with two turbochargers, one for high and one for low pressure. It incorporates engine shutoff during braking (which Chrysler started using around 2009), a stop/start system to shut the engine when at a full stop, and a technology not yet used in production cars, creating electricity from engine waste heat.

The program, which is set to continue through April 2013, is a roughly 50/50 project between the Department of Energy ($14.5 million) and a consortium of Chrysler, Delphi (the former GM parts division), Ohio State University, and the Argonne National Laboratory ($15.5 million).
