| Abstract: | This paper presented a new design approach of the sensor in automobile electronically controlled gas-injection control system,which was used to control gas discharge rate accurately.It replaced the multi-coil potentiometer in imported products with differential inductive displacement sensor to measure the opening information of gas-injection value.Compared with imported alike products,the system adopting the new sensor has the same performance,better stability and cheaper cost. |
