Mazda SKYACTIV-G 1.3 Engine Wins 2012 RJC Technology of the Year

Mazda’s newly developed KYACTIV-G 1.3 engine has been named the 2012 Automotive Researchers’ and Journalists’ Conference of Japan (RJC) Technology of the Year. The SKYACTIV-G 1.3 engine is available in the new Mazda Demio (known overseas as the Mazda2) in the Japanese market. The breakthrough Mazda SKYACTIV-G 1.3 achieves a record high compression ratio of 14.0:1 and exhibits outstanding efficiency, especially under high load at low rpm. In order to avoid knocking – an unavoidable issue with conventional high-compression engines – the SKYACTIV-G 1.3 features a number of new technologies, such as piston cavities that are specially designed to support ideal combustion, and multi-hole injectors that enable precise fuel injection control.

The Mazda Demio 13-SKYACTIV model grade combines the SKYACTIV-G 1.3 engine with Mazda’s unique idling stop system, i-stop, and a continuously variable transmission (CVT) to deliver high fuel economy of 30.0km/L (under Japan’s 10-15 mode test cycle) or 25.0km/L (JC08 mode). RJC chairman, Hiroshi Fukunaga, announced the award after the final round of balloting.
