Introduction of crankshaft sensor

Crankshaft position sensor is one of the most important sensors in engine electronic control system. It provides ignition time signal and determines crankshaft position, which is used to detect piston top dead center, crankshaft angle and engine speed. The structure of crankshaft position sensor varies with different models, which can be divided into three categories: magnetic pulse type, photoelectric type and Hall type.

The crankshaft position sensor is installed behind the pulley at the front end of the crankshaft, and the rear end of the pulley has a thin circular toothed disc with fine teeth, which is installed on the crankshaft together with the crankshaft pulley and rotates with the crankshaft. On the outer edge of the signal plate, there are 90 teeth every four circles along the circumference, and they are arranged at 120 degrees 1 flange. A sensor box installed at the edge of the signal panel generates an electrical signal.
