An Engine That Uses 30% Less Fuel

From MIT's Technology Review website comes word of an engine design that uses 30% less diesel fuel. Achates Power, based in San Diego, California, has redesigned the German Jumo engine from the 1930s and the U.S. Army has given Achates, and partner AVL Powertrain Engineering, $4.9 million to build a complete multi-cylinder prototype.

Diesel engines are already very efficient, but this improvement could result in an engine that’s 50% more efficient than those run on gasoline and could cost 10% than a conventional diesel engine.
