19/05/11 - Mazda launches SKYACTIV-G 1.3lt

HIROSHIMA, Japan—Mazda Motor Corporation has announced that the “SKYACTIV-G 1.3” direct-injection 1.3-litre petrol engine will be the first of its next-generation SKYACTIV technologies to be introduced to the market.

Mazda unveiled the engine at the Automotive Engineering Exposition being 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 petrol 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.
