The effect of the pressure sensor: the pressure sensor gives the engine load information content and the intake air degree information content, which can change the burden of the engine intake pipe into the corresponding electrical signal, and the engine electronic device control board calculates the basic oil pump interval, ignition advance Angle and ignition advance Angle according to this signal.

The role of pressure sensor: The pressure sensor provides engine load information, which can convert the pressure of the engine intake pipe into the corresponding electrical signal, and the engine electronic controller calculates the basic fuel injection time, fuel injection amount and ignition advance Angle according to this signal.

Pressure sensors play a big role in automobiles: The pressure sensor used in the EFI engine to detect the intake volume is called the D-type injection system (velocity density type).

The pressure sensor is used to test the absolute pressure of the intake manifold behind the electronic throttle valve, which tests the transformation of the vacuum pump in the intake manifold according to the size of the engine speed ratio and the load, and then converts the voltage signal to the engine control module according to the internal resistance change of the sensor, to control and adjust the ignition advance Angle and ignition timing Angle.
