I like cars as much as the next person, but I’m certainly not an expert. I like seeing what the newest developments are in terms of design, features, colors, and performance. With as much talk as there is these days regarding electric vehicles, it’s interesting to see the latest technological developments in gasoline engines. At CarThrottle, I found an article about the latest in engine tech: Mazda’s New Engine Tech Video Is Fascinating And Mesmerising.
This is Mazda’s new video, showing off its Spark Controlled Compression Ignition combustion cycle, or SPCCI. It’s the super-lean burn cycle the company has been working on, combining elements of petrol and diesel combustion cycles into one. It’s different to the HCCI system because it uses a spark.
In a nutshell the cycle intentionally draws in less petrol on the intake stroke, compresses it much more fiercely than a normal gasoline engine does and then adds a dash of higher-concentrated fuel which is then ignited by a spark plug. That triggers further combustion at multiple points throughout the cylinder.
