| Abstract: | An engine cycle simulation is conducted using CFD code BOOST cgupled with chemical kinetics code CHEMKIN to optimize the valve timing scheme for HCCI in a Chery 2.0L GDI engine. This is the first time in China to realize HCCI combustion in a multi-cylindex; gasoline engine. The results show that the coefficients of cycleto-cycle variation both within and between cylinders are less than 2% , and the fuel consumption and NOx emission are greatly reduced. |
