SKYACTIV-X is a new proprietary internal combustion engine from Mazda that combines the high-revving character of a gasoline engine with the efficiency, torque and response of a diesel. Offering an uncompromised combination of environmental performance, power and acceleration performance, SKYACTIV-X fully enables the Jinba-ittai driving experience Mazda aims to offer customers.
SKYACTIV-X is the world’s first commercial gasoline engine to use compression ignition,2 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.

・ This new proprietary combustion engine combines the advantages of gasoline and diesel engines to achieve outstanding environmental performance, power and acceleration performance.
・ Compression ignition and a supercharger fitted to improve fuel economy together deliver unprecedented engine response and increase torque 10–30 percent*3 over the current SKYACTIV-G gasoline engine.
・ Compression ignition makes possible a super lean burn*4 that improves engine efficiency up to 20–30 percent*3 over the current SKYACTIV-G, and from 35–45 percent*3 over Mazda’s 2008 gasoline engine of the same displacement. SKYACTIV-X even equals or exceeds the latest SKYACTIV-D diesel engine in fuel efficiency.
・ With high efficiency across a wide range of rpms and engine loads, the engine allows much more latitude in the selection of gear ratios, providing both superior fuel economy and driving performance.

I’d like to hear one of the Mazda engineers discuss the “highly responsive air supply unit” in more detail. Kiyoshi Fujiwara-san said that the HRASU injects air into highly compressed cylinders but none of the automotive magazines suggest that it does anything of the sort and say it is a conventional roots supercharger. Did Fujiwara-san misspeak? Was he mis-translated? Are the auto journalists missing something important about the operation of the HRASU?

Raymund Hofmann says:

So all try to build a “Tesla mee too” while Mazda is doing the thing the market wants. This will be a fierce competitor for the still stinking (NOX) Diesel and the overweight, overpriced, environmentally harmful and inconvenient Battery EV.
If this technology is solid, it might even be viable for small trucks still polluting cities with their Diesel engines.

Is that a blower on it??

Bad sound, fix your microphone!

Brent says:

Very cool!  I just want him to tell more about it.

I love mazda

Motor.TV, can you do an edited version of this? The volume needs adjustment. I can hardly hear Dave and then the music is loud afterward. FANTASTIC video otherwise, thank you!

Mr. Mazda says:

Great video but sound needs a tweak. Thanks for sharing this on such an enthralling subject!
