HIROSHIMA, Japan--May 18, 2011: Mazda Motor Corporation has announced that the "SKYACTIV-G 1.3" direct-injection 1.3-liter gasoline engine will be the first of its next-generation SKYACTIV technologies to be introduced to the market. Mazda will unveil the engine at the Automotive Engineering Exposition that will be held from May 18 through 20, 2011, at the Pacifico Yokohama convention center near Tokyo, Japan.
The breakthrough SKYACTIV-G 1.3 achieves a record high compression ratio (for a regular gasoline mass production automobile engine) of 14.0:1 and exhibits high 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.
Mazda plans to introduce the SKYACTIV-G 1.3 to the Japanese market in the facelifted Mazda Demio (known overseas as the Mazda2) during the first half of 2011. It will be the first ever 1.3-liter direct-injection gasoline engine to be equipped in a compact car manufactured in Japan. Combined with Mazda's unique idling stop system, i-stop, and a continuously variable transmission (CVT), SKYACTIV-G 1.3 will achieve fuel economy of 30km/L under Japan's 10-15 mode test cycle.
Mazda has applied for over 130 patents in relation to the engine (as of the end of February, 2011).
