Mazda SKYACTIV-D 2.2 diesel engine explained
The Mazda6 from its launch has been regarded as one of the best-handling, most engaging vehicles in its segment. Now it raises the bar once again with the company’s first SKYACTIV-D 2.2 diesel engine which is mated to an automatic transmission.
The SKYACTIV-D 2.2 common-rail diesel features three new systems to raise responsiveness and reduce engine noise: High-Precision DE Boost Control enhances boost pressure control to sharpen the response to accelerator inputs; a Natural Sound Smoother uses a damper to stifle diesel knock range; and Natural Sound Frequency Control deviates engine timing to neutralise pressure waves, suppressing three critical frequency bands in which engine components typically vibrate most loudly.
This increase in engine quietness is complimented by a comprehensive improvement in sound insulation aboard this latest Mazda6, with the adoption of improved door seals, tighter tolerances between panels, and sound insulation materials added to the underbody, rear console, headliner and doors. Laminated front side windows further suppress wind noise.
Typical of any diesel, the engine isn’t averse to the upper reaches of the rev range. The 173bhp 2.2-litre unit builds momentum in a nice, progressive way, pulling easily all the way to the limiter when summoned. It is an impressive runner and very frugal with its use of premium BHPetrol diesel.
