| 摘 要： | 试验结果表明，在各种负荷工况下，ＥＱ６１００型汽油机采用ＥＧＲ后其ＮＯｘ排放都显下降，但ＨＣ、ＣＯ排放及燃油消耗率随ＥＧＲ率的变化则较为复杂，而因各工况下均存在一个最佳ＥＧＲ率。通过试验，给出了ＥＱ６１００型汽油机２０００ｒ／ｍｉｎ下最佳ＥＧＲ率随负荷变化的曲线，为其排气背压控制ＥＧＲ系统的设计提供了依据。

| Abstract: | The test results show that NOx emissions from Model EQ6100 gasoline engine are obviously reduced under various load conditions after the EGR is used. But the HC,CO emissions and fuel consumption rate are in complicate conditions with the change of EGR rates,so an optimum EGR rate is existed under every engine working conditions. By tests,an optimum EGR rate curve with the change of load of model EQ6100 gasoline engine working at 2000 rpm is obtained, and it provides a design criterion for EGR system of exhaust gas back pressure control. |
