通过在VOLVOB230F型电控汽油喷射发动机上研究节气门位置传感器的全负荷信号对发动机性能的影响,并对节气门位置传感器故障造成的发动机性能变化的对比可分析表明:节气门位置传感器的全负荷信号丢失以后,混合气变稀,功率下降;CO和HC排放降低,NOx排放升高,同时有助于指出了节气门位置传感器在电控发动机故障诊断中的作用。
Through the VOLVOB230F electronically controlled gasoline injection engine throttle position sensor full load signal on the engine performance and throttle position sensor failure caused by changes in engine performance comparison can be analyzed: the throttle position sensor full load After the signal is lost, the mixture becomes thinner and the power decreases; the CO and HC emissions are reduced and the NOx emission is increased; meanwhile, it is helpful to point out the function of the throttle position sensor in the fault diagnosis of the electronically controlled engine.
