A brochure from Slovakia shows what sort of output Mazda’s new supercharged compression ignition petrol engine – dubbed Skyactiv-X – will offer in the new Mazda3.
According to the document discovered by the folks over at Jalopnik, the new engine will be offered with 133 kW and 222 N.m. Although the brochure doesn’t specify capacity, it’s thought the new engine displaces 2,0 litres.
In Slovakia, at least, this powerplant will be available in front- and all-wheel-drive flavours, and with either a manual or automatic transmission. Fuel consumption or performance claims have yet to be made.
Skyactiv-G petrol and Skyactiv-D diesel engines will also be offered.
When confirming the new engine in 2018, Mazda said its “proprietary combustion method called Spark Controlled Compression Ignition” overcame two issues that had impeded commercialisation of compression ignition petrol engines.
The first issue was maximising the zone in which compression ignition was possible, while the second was achieving a “seamless transition” between compression ignition and spark ignition. This suggests Mazda’s new engine sees conventional spark plugs retained and used in conjunction with compression ignition.
“This new proprietary combustion engine combines the advantages of gasoline and diesel engines to achieve outstanding environmental performance, power and acceleration performance,” the automaker said.
According to Mazda, the combination of compression ignition and a supercharger would both improve fuel economy and deliver “unprecedented engine response”, with a 10 to 30 percent increase in torque over the current Skyactiv-G petrol engine, thanks to a “super lean burn”.
Mazda added the new engine would even “equal or exceed” its latest diesel mill in terms of 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,” it said.
