The new generation 2.0L gasoline engine utilizes extra high compression ratio compared with conventional gasoline fueled engine. Under part load condition, with the assistance of compression ignition combustion, highly diluted/lean mixture combustion were realized, resulting a large improvement in vehicle fuel economy. In this paper, the combustion technology of new generation gasoline engine with spark controlled compression ignition is described in detail.
