Air flow sensor, also known as air flow meter, is one of the important sensors of EFI engine. It converts the inhaled air flow into an electric signal and sends it to the electronic control unit (ECU) as one of the basic signals for determining fuel injection. It is a sensor that measures the air fl......

Spark plugs are generally classified according to material and shape. Let me introduce you to spark plugs.

The function of the camshaft position sensor is to collect the camshaft dynamic angle signal and input it into the electronic control unit (ECU) to determine the ignition timing and fuel injection timing.

The photoelectric crankshaft and camshaft crankshaft sensor is improved by the distributor, which is mainly composed of the signal plate (namely the signal rotor), the signal generator, the distributor, the sensor housing and the wiring harness plug.

The structural characteristics of the photoelectric camshaft position sensor have been introduced last time, and this time I will introduce its working principle.

The crankshaft sensor is usually installed in the distributor and is one of the most important sensors in the control system.
