A gasoline engine that runs as clean as an electric vehicle? Last year, Mazda introduced to the public their upcoming innovative engine called Skyactiv-X. The new engine is designed to work similar to a gasoline and diesel engine at the same time, reducing emissions produced by an internal combustion engine. A more detailed explanation can be found in our feature of how Mazda's Skyactiv-X engine works.
The Hiroshima-based automaker has yet to release the upcoming Skyactiv-X but has already revealed development plans of a next-generation powerplant technology called Skyactiv-3. A report from Automotive News says that the future engine will have emission levels on par with that of an electric vehicle as revealed by Mazda's powertrain chief Mitsuo Hitomi during an automotive technical conference in Tokyo.
Currently, the Skyactiv-X engine is slated to be introduced in 2019. After that, Mazda will be focusing on increasing thermal efficiency of the engines. In order for the said Skyactiv-3 to have emissions similar to that of an EV, Mazda still needs to increase the thermal efficiency of the engine to 56-percent.
Mazda compares the numbers by measuring the carbon dioxide emitted from producing the electricty that powers an EV. In an internal combustion engine, emissions are calculated from the extraction of oil and refining of gasoline. According to Mazda's calculations, it shows that some EVs are actually dirtier than currently existing fuel-efficient, gasoline vehicles.
Hitomi did not detail a timeline about the upcoming Skyactiv-3. However, don't expect it to be introduced anytime soon as Skyactiv-X has yet to be offered on any production car. He did say however, that the future engine will help prolong the life of internal combustion engines in the future of electrification.
