In this video, we’ll look at what changes to the rotary engine could result in great efficiency. This includes changes to the compression ratio, fuel injection, SPCCI lean-style combustion, superchargers, and using a pressure sensor to optimize ignition timing.Engineering Explained

From Mazda’s Press Release regarding SkyActiv-X:SKYACTIV-X is the world’s first commercial gasoline engine to use compression ignition, in which the fuel-air mixture ignites spontaneously when compressed by the piston.


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…./Engineering Explained
