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).

Ciatti's Gasoline-Burning Diesel Engine Emits Less Soot and Nitrous Oxides
Diesel and gasoline engines have been the only way to move around since the 19th century (maybe with some small, electric exceptions for a short while). Though having low efficiency numbers (20 percent) when compared to their counterparts, gasoline engines still found their place on the market, mostly because in the first hundred years they had the advantage of being quicker, more responsive and now for not emitting soot and nitrous oxides.
