Mazda Engineers win SAE Outstanding Technical Paper Award for HCCI Paper

Quote:

The technical paper analyses the effects of different fuel components on ignition performance in a high-compression gasoline HCCI engine, and develops a theoretical model that predicts auto-ignition timing for the various grades of gasoline used in different markets. The paper also shows that, when the engine is operated with a standard spark ignition, the extra heat generated as the piston approaches top-dead-center does not increase the likelihood of knocking (abnormal combustion), enabling increased power output. Mazda's breakthrough SKYACTIV-G gasoline engine, which significantly improves fuel economy and torque thanks to the world's highest compression ratio of 14.0:1, utilizes the results of this analysis.

The award goes to

Takashi Youso, Powertrain Development Div., Mazda Motor Corporation
Masahisa Yamakawa, Powertrain Development Div., Mazda Motor Corporation

and also two co-authors from outside of Mazda

Shigeyuki Tanaka, Cosmo Oil Co., Ltd.
Jin Kusaka, Waseda University

I had read something else awhile ago that mentioned HCCI in connection with the Sky G. It seems like Sky G is an intermediate step to HCCI. Using some HCCI ideas while still utilizing a spark.
