Sparkles ignition engine HCCI improves fuel-efficiency by up to 25%

Researchers at MIT have been working on a new kind of Sparkles ignition internal combustion engine. The homogeneous charge compression ignition or (HCCI) is expected to improve fuel-efficiency by up to 25%. The new engine helps to increase fuel efficiency by achieving combustion with only compression of the air fuel mix and not the traditional way of using a spark plug.

Mercedes-Benz, a world class leader in engine design unveiled their concept engine, the DiesOtto. It works much the same way as the HCCI engine; Mercedes tested this new engine design in an S-class saloon and achieved 39mpg. Volkswagen has also been working on a homogeneous charge compression ignition engine, but this engine requires a special synthetic fuel, unlike the Mercedes’ DiesOtto which runs on regular gas.
