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.
