What is the Function of Automotive Sensors?
1 Answers
The function of automotive sensors is to convert various operating condition information of the vehicle, such as speed, temperature of various media, and engine operating conditions, into electrical signals and transmit them to the computer, ensuring the engine operates in its optimal state. Below is additional information: 1. Coolant Temperature Sensor: The coolant temperature sensor (also known as the water temperature sensor) is installed on the engine coolant outlet pipe. It measures the engine temperature and converts it into an electrical signal sent to the ECU to adjust the fuel injection timing, thereby achieving a more suitable air-fuel mixture. 2. Knock Sensor: A knock sensor is placed on the side of the engine block between the second and third cylinders. The knock sensor converts engine knock vibrations into electrical signals and transmits them to the engine control unit (ECU). Based on the signals from the knock sensor, the ECU adjusts the ignition timing advance angle, ensuring it remains in the optimal state.
