Mazda has announced the introduction of the world’s first commercial engine to use a compression ignition, the Skyactiv-X engine. Mazda’s new engine uses a compression ignition, in which the fuel-air mixture ignites spontaneously when compressed by the piston.

The Skyactiv-X engine is expected to debut in the next-generation Mazda3

Mazda says that a proprietary combustion method called Spark Controlled Compression Ignition overcomes two issues that had impeded commercialization of compression ignition gasoline engines: maximizing the zone in which compression ignition is possible and achieving a seamless transition between compression ignition and spark ignition.

The new engine will combine the advantages of gasoline and diesel engines. It will also use a supercharger that will help it produce 10-30 percent more torque than Mazda’s current Skyacti-G engine. The new Skyactiv-X engine will also be 20-30 percent more fuel efficient.

Mazda hasn’t announced which model will get the new engine first, but it’s being reported that it will debut under the hood of the new Mazda3.
