| 摘 要： | 采用切断氧传感器的方法,研究发动机性能的变化.试验发现,由于怠速时发动机温度较低,氧传感器在发动机怠速时在空燃比反馈控制中不起作用.怠速时断开氧传感器对发动机影响不大,在负荷试验中,断开氧传感器后,发动机不受空燃比反馈控制,耗油变大,混合气比有氧传感器时变浓,排放恶化明显.

| Abstract: | This paper uses the method of cut-off oxygen sensor to make a study of the engine performance change and finds that the oxygen sensor is inoperative in the air fuel ratio feedback control,fuel consumption increases and discharge deterioration is obvious because engine temperature is lower when it is at idle speed control. |
