Names of various sensors on Magotan.

Automotive sensors used to be only used in engines, but now they have been extended to chassis, body, lighting and electrical systems. More than 100 sensors are used in these systems. Among various sensors, the most common one is:1,which is used for electronically controlled fuel injection engines. The intake pressure sensor reflects the change of absolute pressure in the intake manifold and provides a reference signal for ECU (Engine Electronic Control Unit) to calculate the fuel injection duration. Air flow sensor: measures the amount of air inhaled by the engine and provides it to ECU as a reference signal for fuel injection time; Throttle position sensor: measures the throttle opening and provides it to ECU as a reference signal for fuel cut-off, air-fuel ratio control and ignition advance angle correction; Crankshaft angle sensor: detects the rotating speed of crankshaft and engine, and provides it to ECU as reference signal to determine ignition timing and working sequence; Oxygen sensor: detects the oxygen concentration in the exhaust gas and provides it to ECU as a reference signal to control the air-fuel ratio near the optimal value (theoretical value); Air temperature sensor: detects the intake air temperature and provides it to ECU as the basis for calculating air density; Water temperature sensor: detects the temperature of coolant and provides engine temperature information to ECU; Deflagration sensor: installed on the cylinder block, it detects the deflagration of the engine and provides it to ECU to adjust the ignition advance angle according to the signal. 2. Sensors used in chassis control These sensors are mainly used in transmission, steering gear, suspension and ABS. Transmission: there are speed sensors, temperature sensors, shaft speed sensors, pressure sensors, etc. The steering device includes angle sensor, torque sensor and hydraulic sensor; Suspension: speed sensor, acceleration sensor, body height sensor, roll angle sensor, rotation angle sensor, etc.
