How many sensors are there on the engine?

Hello, all engines now use electronic control system. The electronic control system is mainly composed of various sensors, electronic control unit (ECU) and actuators. The control system is mainly divided into five aspects, including air intake system, fuel system, ignition system, idle system and emission control system. The following is a schematic diagram: The main sensors (nine sensors) of the engine include: air flow sensor (MAF), throttle position sensor (TPS), accelerator pedal position sensor (ETPS), air temperature sensor (MAT), coolant temperature sensor (ECT), camshaft position sensor (CMP), crankshaft position sensor (CKP), oxygen sensor and knock sensor (KS). Their specific positions on the engine are shown in the following figure: The main signals for controlling the fuel injection quantity are the air flow sensor and the crankshaft position sensor. The correction signal is an oxygen sensor. Additional signals are coolant temperature sensor and air temperature sensor. The main signals of ignition signal are crankshaft and camshaft position sensors. The correction signal is a knock sensor. The additional signal is the coolant temperature sensor. Summary: Here is just a brief introduction of its components. To learn more, please study deeply! I hope the above answers can help you. If you find it useful, please like it!
