Where is the engine sensor located?

[VonGarrett]

The engine speed sensor is generally mounted on the flywheel. Below is an introduction to the classification of engine sensors: 1. Crankshaft position sensor: 1. Function: It is the most important sensor in the computer-controlled ignition system. Its role is to detect top dead center signals, engine speed signals, and crankshaft angle signals, and input them into the computer to control the ignition sequence of the cylinders and issue the optimal ignition timing commands. 2. Types: Electromagnetic induction type, Hall effect type, photoelectric effect type. 2. Camshaft position sensor: Function: Collects the position signal of the valve camshaft and inputs it into the ECU, so that the ECU can identify the top dead center of the compression stroke of cylinder 1, that is, provide the cylinder identification signal (the cylinder identification signal is the sole basis for the ECU to perform fuel injection timing and sequential control), thereby enabling sequential fuel injection control, ignition timing control, and knock control. It is also used to identify the first ignition timing at this moment.
