What is the function of automobile sensor?

The function of vehicle sensor is to convert various working conditions information, such as vehicle speed, various medium temperatures, engine working conditions, etc. Converted into electrical signals and transmitted to the computer, so that the engine is in the best working condition. The following is extended information:

1. Coolant temperature sensor: The coolant temperature sensor (also called water temperature sensor) is installed on the engine coolant outlet pipe to measure the engine temperature and convert it into an electrical signal to be transmitted to the ECU to correct the fuel injection timing, so as to obtain a mixture with a more appropriate concentration. 2. Knock sensor: The knock sensor is arranged between the second cylinder and the third cylinder. The knock sensor on the side of the cylinder can convert the vibration generated by engine knock into electrical signals and transmit them to the engine control unit ECU. ECU corrects the ignition advance angle according to the signal transmitted by the knock sensor, so that the value of the ignition advance angle is always in the best state.
