Mazda’s new SKYACTIV-X engine

The Association of Scottish Motoring Writers (ASMW) has acknowledged Mazda’s forthcoming SKYACTIV-X engine with the Technology Award at their annual awards ceremony. SKYACTIV-X is the world's first commercial petrol engine to use compression ignition, in which the fuel-air mixture ignites spontaneously when compressed by the piston.

Mazda’s proprietary combustion method -Spark Controlled Compression Ignition (SPCCI) - combines the spark ignition of a petrol engine with the compression ignition of a diesel ensuring that SKYACTIV-X delivers the free-revving character of a petrol engine with the fuel economy, low CO2, torque and response of a diesel engine.

Having experienced a prototype SKYACTIV-X engine earlier this year ASMW President, John Murdoch said: “it’s very clear this revolutionary petrol engine has the potential to give customers the best bits of petrol and diesel in one package. With the promise of a class-leading combination of performance, low emissions and economy, it’s a testament to Mazda’s engineering ingenuity that a relatively small brand can bring such a unique engine to market.”
