- Abstract:
- Combustion performance of DME fueled homogeneous charge compression ignition(HCCI) engine under different exhaust gas recirculation (EGR) rate and different coefficient of excess air (?) was studied numerically by using the software CHEMKIN. Influences of EGR and ? on the combustion performance of DME HCCI engine were analyzed. The result showed that at a specific ?, the pressure, temperature and the heat release rate decreased with the increase of EGR rate and the high temperature reaction was delayed. With a specific EGR rate, the pressure, temperature and the heat released rate in cylinder decreased with the increase of ? . And the low temperature reaction advanced while the high temperature reaction delayed. It could be recognized that the ignition time of HCCI engine could be controlled by changing the EGR rate or ? .
