This engine uses no spark plugs and runs cleaner than a hybrid. It's called HCCI, homogeneous charge compression ignition. Instead of using spark to ignite fuel, it compresses the fuel air mixture until it explodes on its own, like a diesel but using gasoline. Mazda experimented with this in their SkyActiv-X engines, blending the best of gas and diesel for better efficiency, lower emissions, and smooth performance. It's ultra efficient, but incredibly hard to control. Why? Because even slight ch
