New Engine Prototype That Mixes Gasoline and Diesel Gets 55 Percent Efficient

Researchers from the University of Wisconsin-Madison have recently unveiled a concept engine that can be from 20 to 30 percent more fuel-efficient than classic models. It would also be substantially cheaper to produce, since the emissions are lower than those of conventional engines and expensive catalyst units are not needed any longer (in some cases, their price can reach that of the engine's).
