The engine speed sensor is an inductive sensor that captures the engine speed and the exact angular position of the crankshaft (input system). A separate signal wheel for the engine speed sensor is mounted on the flywheel.
The signal wheel is designed as a wheel with a number of segments, divided into 60 segments. Each time the signal is rotated through the sensor, an AC voltage is generated, the frequency of which varies with the speed of rotation. The frequency is the speed. In order to identify the crankshaft position, the signal wheel has a gap between the two tooth segments. The engine speed sensor is used to identify the engine speed. It identifies the engine 1 cylinder ignition top dead center together with the Hall sensor. Determine the injection time and ignition timing.
