The function of the engine speed sensor

1. The answer is, the engine speed sensor It is the condition to identify the start of the engine, because the speed sensor detects the stop point on the cylinder of the engine.

2. The engine speed sensor, also known as the crankshaft phase sensor, is one of the most important sensors in the automatic control system of the electric injection engine.

3. The engine speed sensor is an induction sensor that obtains the engine speed and the exact angle position of the crankshaft (input system). A signal wheel for the engine speed sensor is installed on the flywheel.

The role of automobile engine sensor

The air flow sensor, the function of which is to measure the air flow entering the engine and install it on the air side channel. The intake pressure sensor is installed on the intake manifold by detecting the negative pressure change of the intake manifold to sense the size of the air intake volume of the engine.

The antifreeze temperature sensor is installed on the water cover of the engine cylinder head. It is used to measure the temperature of engine antifreeze. The function of the intransitive verb temperature sensor is that the mass of the gas entering the engine is related to the intake temperature and atmospheric pressure.

Sensor refers to a device or device that can sense the specified measurement and convert it into a usable signal according to a certain law. It is usually composed of sensitive elements and conversion elements.

Throttle position sensor Function: Throttle position sensor is to monitor the opening angle of the throttle valve.The size, determine the idle speed, full load and deceleration conditions, so as to implement various fuel injection control corresponding to the opening state of the throttle valve. Failure impact: idle speed suddenly high and low, or cause the phenomenon of flying car.

What is the function of the engine sensor

1. The function of the air flow sensor is to measure the air flow into the engine and install it on the air side channel. The intake pressure sensor is installed on the intake manifold by detecting the negative pressure change of the intake manifold to sense the size of the air intake volume of the engine.

2. Engine speed and camshaft position sensors are the most critical sensors in the engine centralized adjustment system, which are used to measure engine speed and confirm the crankshaft position. The throttle position sensor is installed on the throttle body, including a linear throttle pomometer and an idle switch.

3. Meet the requirements of information transmission, processing, storage, display, recording and control. It is the first link to realize automatic detection and automatic control. A sensor is a measuring device that converts the measured into a certain physical quantity that is related to it and is easy to apply with a certain accuracy and regularity.

4. The throttle position sensor function: The throttle position sensor is to monitor the size of the throttle opening angle and determine the idling speed, full load and deceleration conditions, so as to implement various fuel injection control corresponding to the opening state of the throttle valve. Failure impact: idle speed suddenly high and low, or cause the phenomenon of flying car.

5. The function of the engine speed and crankshaft position sensor is to determine the position of the crankshaft, that is, the angle of the crankshaft and the engine speed. It usually works with the camshaft position sensor to determine the basic ignition moment.

6. There are several sensors and their functions in the engine electronic control system: (1) Air flow sensor: installed on the engine intake manifold to measure the air flow into the engine. The information feedback from the sensor is an important basis for the ECU to calculate the amount of fuel injection.
