Extended data:

Common functions of sensors:

1, which reflects the change of the absolute pressure of the intake manifold, is a reference signal for ECU (Engine Electronic Control Unit) to calculate the fuel injection duration.

2. Measure the amount of air inhaled by the engine and provide it to ECU as a reference signal for fuel injection time.

3. Measure the throttle opening and provide it to ECU as a reference signal for fuel cut-off, air-fuel ratio control and ignition advance angle correction.

4. Detect the rotating speed of crankshaft and engine, and provide it to ECU as a reference signal to determine the ignition timing and working sequence.

5. Detect the oxygen concentration in the exhaust gas and provide it as a reference signal to ECU to control the air-fuel ratio near the optimal value (theoretical value).

6. Detect the intake air temperature and provide it to ECU as the basis for calculating the air density.

7. Detect the temperature of coolant and provide engine temperature information to ECU.

8. It is installed on the cylinder block to detect the engine deflagration and provide it to ECU to adjust the ignition advance angle according to the signal.
