摘要
文章对3台市场保有量较大的不同实验车辆进行氧传感器信号缺失和空气流量信号缺失后的CO,HC和NO_x排放测试,并与正常状况下的车辆排放实验结果进行比较.研究结果表明,在现代车辆喷油脉宽的闭环控制中,单一主要传感器信号的缺失对车辆的排放影响有限.
Testing models of three different sensors and mass airflow sensors. The HC, CO popular brand name cars were tested on failures of oxygen and NOx pollutant emissions data of these testing cars are compared to the normal testing emission data. The results show that the influence of a single major sensor signal missing on car＇s emission is limited because of the closed-loop control of the modem car＇s fuel injection pulse width.
