Spark-free SkyActiv: Mazda Seems Well Prepared for the Future, Without Electricity's Help
While it wasn’t the only car company to make use of a rotary engine, it was certainly the only one to be competitive with them when pistons and pushrods would easily have sufficed. However, those days are gone. Mazda’s SkyActiv technology is well suited for squeezing out an engine’s true potential, but it doesn’t feel particularly quirky or unique.
That could change with the company’s second generation of SkyActiv engines. Mazda is one of only two automakers planning to introduce a motor with homogenous charge compression ignition (HCCI) sometime next year. If you’re unfamiliar, that’s a direct-injection gasoline-powered motor that uses compression, not spark, to ignite fuel — something typically reserved for diesel powerplants.
