Compression ignition in a gasoline engine has been seen as the holy grail of engine technology by many engineers and for 2019 Mazda has finally made it a reality. While some may say that SPCCI (Spark Controlled Compression Ignition) isn’t true compression ignition I disagree. Mazda’s engineers took a pragmatic approach to the issues surrounding compression ignition and instead of fighting the spark plug, they embraced it to solve the issues other companies encountered when trying to make this work. If all goes to plan this engine will be found under the hood of a Mazda you can actually buy next year.
