Mazda Invents Diesel-Like Gasoline Engine with 30% Greater Fuel Efficiency

Mazda announced a significant breakthrough, a petrol engine that works more like a diesel engine and is 20% to 30% more fuel efficient than its current engines.

The new homogenous charge compression ignition engine ignites gasoline through compression, virtually eliminating the use of spark plugs except in very cold temperatures. The net result is fuel economy that should match that of a diesel engine but without the associated negatives including high emissions of nitrogen oxides or sooty particulates.

Mazda sees the development as extending the life of gasoline-powered engines even as electric vehicles gain market share.

“We think it is an imperative and fundamental job for us to pursue the ideal internal combustion engine,” said Mazda’s head of research and development, Kiyoshi Fujiwara, in a briefing with reporters. “Electrification is necessary but… the internal combustion engine should come first.”

Automakers have been trying to develop such engine technology for decades and Mazda is apparently the first to commercialize it. The Japanese automaker said it expects to offer vehicles with the new engine in 2019.
