TOKYO — Mazda Motor Corp. is developing a gasoline engine it says will be as clean as an electric vehicle — at least when the supply chain of energy creation is calculated into it.
Mazda's powertrain chief revealed the plan during an automotive technical conference here, dubbing the future engine technology Skyactiv-3.
The nomenclature signals that Mazda is working on another generation of Skyactiv high-compression engines.
The first generation, called Skyactiv-G, debuted in 2011. The second generation, Skyactiv-X, will reach the market in the fiscal year ending March 31, 2019.
After that, the automaker will prioritize boosting the thermal efficiency of its engines, said Mitsuo Hitomi, Mazda's managing executive officer in charge of powertrain. Doing so reduces the amount of combustion energy lost to heat while increasing the amount harnessed to power the wheels.

If Mazda can increase the thermal efficiency of its third-generation Skyactiv engine by about 27 percent, to 56 percent, it can achieve emissions on a par with an EV, Hitomi said.
