transmission fluid pressure sensor
The function of the transmission pressure sensor is to monitor the absolute pressure in the intake manifold according to the load state of the engine, and then convert it into an electrical signal and a speed signal, transmit the signal to the car computer, and determine the amount of fuel injection according to the transmitted information.
The working principle of the transmission pressure sensor is to detect the pressure of the intake manifold behind the throttle valve. It detects the change of the manifold pressure according to the engine speed and load, and then transmits the signal to the engine control unit. The ECU receives the signal and controls The size of the fuel injection. When the engine is working, the smaller the throttle opening, the larger the vacuum degree of the intake manifold, the smaller the absolute value in the manifold, and the smaller the output signal voltage. The greater the throttle opening, the smaller the vacuum of the intake pipe, the greater the absolute pressure of the manifold, and the greater the output signal pressure. The transmission is one of the main components of the automobile transmission system. The transmission can change the transmission ratio, adapt to the unwanted driving environment, and make the engine work effectively. It is also possible to drive the engine in reverse. Use neutral to interrupt power transmission to start and idle the engine.
The transmission is a mechanism used to change the speed and torque from the engine. It can change the transmission ratio of the output shaft and the input shaft in a fixed or divided gear, also known as a gearbox. The transmission consists of a variable speed transmission mechanism and a control mechanism, and some cars also have a power output mechanism.
The sensor expert network proposes that the pressure sensor is usually composed of a pressure sensitive element and a signal processing unit. According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors and absolute pressure sensors, it can perceive all physical quantities related to magnetic information. The Hall effect was discovered by German physicist Hall in 1879 when he studied the properties of current-carrying conductors under force in a magnetic field, hence the name. The small magnet is fixed on the turntable, and the turntable is connected to the motor shaft and rotates synchronously. When the small magnet passes through the Hall sensor, the Hall sensor generates a corresponding pulse, and the interval time between two consecutive pulses can be calculated to calculate the measured speed.The content of the function of the transmission pressure sensor has been sorted out here. After reading it, do you know how the pressure sensor works? In short, I hope you can study more about the pressure sensor.
