The Reality of Crankshaft Position Sensor Based on Geely Prospect

1. Sensors can be roughly divided into air intake system, oil supply system and ignition system according to their systems.

1. Sensors of intake system include air flow meter, throttle position sensor, intake absolute pressure sensor, etc. The fuel supply system consists of coolant temperature sensor, absolute pressure sensor and oxygen sensor. The ignition system consists of crankshaft position sensor and cylinder synchronous signal generator or camshaft sensor, which are also the reference signals of the whole engine. The engines will control the timing of fuel injection and ignition according to their signals.

In addition, the engine has some auxiliary sensors. For example, in order to ensure that the engine is easy to stall at idle speed, a power steering sensor is installed on the high-pressure pipeline of the steering power system, which can improve the idle speed of the engine during steering and prevent stalling. In the air conditioning system, there are also air conditioning request signals and engine control unit, whose function is to improve the idle speed when the engine is idling and prevent the engine from stalling when the engine is overloaded.

Second,

1. In the air conditioning system, there is an air conditioning temperature sensor, which is used to feed back signals to the air conditioning control unit for temperature control. There are also air outlet temperature sensors and sunshine temperature sensors affected by outdoor temperature.

2. There is also a speed sensor on the chassis, and four wheels of the automatic braking system are provided with wheel speed sensors to ensure the rotation speed of the four wheels when the vehicle brakes and prevent the vehicle from running off.

3. In the safety system, there are control sensors for seat belts and airbags in the front and rear bumpers of the vehicle.

From this point of view, there are many sensors in the vehicle. It mainly depends on the basic configuration of your vehicle. The higher the vehicle configuration, the higher the equipment, the more things and the more sensors.
