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.

BMW Develops Hydrogen Powered ICE Based on Diesel Technology
It's a known fact that diesel engines are more efficient than the gasoline ones, and that is because they work a little differently on the ignition side. Diesel engines compress the fuel to a point where it heats and explodes, a process known as self-ignition. On the other hand, diesel engines are still polluting the atmosphere.
