节气门位置传感器在电控燃油喷射系统中的作用十分重要。它的主要功能是检测节气门开度及怠速状态,并将节气门打开的角度转换成相应的电压信号输送到发动机ECU中。ECU根据收到的信号确定发动机的运行状况(怠速、小负荷、大负荷),并与其他传感器(如水温传感器、空气流量计、曲轴转速传感器等)送达 The role of throttle position sensors in electronically controlled fuel injection systems is very important. Its main function is to detect the throttle opening and idle state, and the throttle opening angle into the corresponding voltage signal delivered to the engine ECU. The ECU determines the operating condition of the engine (idling, light load, heavy load) based on the signal received and communicates with other sensors (such as water temperature sensors, air flow meters, crankshaft speed sensors, etc.)
