Highly-efficient engines developed in pursuit of ideal combustion

The development of automotive mechanisms for engines has a history going back more than 120 years and has involved the work of countless engineers. For this reason we tend to find it difficult to think that any further improvement in performance is possible. But the fact remains that 70 to 80 percent of the energy contained in fuel is lost within a vehicle’s powertrain and fails to be transferred as motive power to its wheels.

Many of today’s automakers are working on engine refinement by making engines smaller and various other methods. One of Mazda’s recent developments towards an ideal engine configuration is the Homogenous Charge Compression Ignition (HCCI) engine, which offers the combined advantages of both gasoline and diesel engines. In commercializing the rotary engine and through other remarkable technical achievements, Mazda has a history of making the seemingly impossible possible. Now, we have taken on the challenge of pursuing ideal combustion.

SKYACTIV-G A new-generation highly-efficient direct-injection gasoline engine that achieves the world’s highest gasoline engine compression ratio of 14.0:1 with no abnormal combustion (knocking) See Details
SKYACTIV-D A new-generation clean diesel engine that will meet global emissions regulations without expensive NOx aftertreatments thanks to the world’s lowest diesel engine compression ratio of 14.0:1 See Details
