An Experimental Investigation on a New Squish Jet-Turbulence Combustion Chamber for SI Engine

Compared with bathtub combustion chamber which is widely used in SI engines especially in China, this paper introduces an experimental investigation on the performances of SI test engine with a new squish jet-turbulence combustion chamber. The new chamber can combine inlet swirl and squish effectively. Results show that the engine with the new chamber gives better comprehensive performances. The combustion process shortens, and the lean burn limit extends.
