Different types of sensors have different functions in automobiles. There are many kinds of automobile sensors. Today, let's learn what types of common automobile sensors are and what the functions of these sensors are.
The pressure sensor is mainly used to sense the vacuum pressure formed by the intake flow rate, and convert it into electrical signal and send it to the microcomputer controller. After the controller calculates and processes it, it sends out the signal of fuel injection quantity and fuel injection time.
The vehicle speed sensor is used to measure the driving speed of the engine and send the signal to ECU to control the air-fuel ratio of engine idling and vehicle acceleration and deceleration.
Air flow sensor
The air flow sensor is used to measure the amount of air inhaled by the engine, which is replaced by electrical signal and provided to ECU as the reference signal of fuel injection time.
The ABS sensor is used to monitor the vehicle speed. In case of emergency braking, the speed of the wheel is fed back to the braking system. The braking system controls the wheel rotation to achieve the best braking effect;
Solar term door position sensor
The throttle position sensor is used to detect the opening of the throttle valve. It measures the angle voltage signal of the throttle opening through the linkage of the lever mechanism and the throttle valve, and transmits the signal to the ECU as the reference signal of fuel injection quantity and ignition advance angle correction.
Crankshaft position sensor
The crankshaft position sensor is used to detect the top dead center signal, crankshaft angle signal and engine speed signal, and provides the ECU as the reference signal to determine the ignition timing, fuel injection timing and working sequence.
Camshaft position sensor
The camshaft position sensor can detect camshaft position and angle, and provide ECU crankshaft angle reference position signal as the main control signal of fuel injection timing control and ignition timing control.
Water temperature sensor
The water temperature sensor is used to sense the temperature of engine cooling water, i.e. cold start and warm-up signals. At this time, the microcomputer controller outputs the control signal to increase the fuel injection quantity, so as to enrich the mixture and facilitate the cold start and rapid warm-up of the engine.
