How many sensors does Wuling Light EFI engine have? What directly affects fuel consumption?

The main sensors of Guang Zhi engine are: crankshaft position sensor, camshaft position sensor, front and rear oxygen sensor, intake pressure sensor, air temperature sensor, water temperature sensor, knock sensor and throttle position sensor.

According to my technical experience, oxygen sensor and intake pressure sensor directly affect fuel consumption.

1. The oxygen sensor monitors the exhaust emission and whether the air-fuel ratio is rich or lean. Sensor data directly participate in computer calculation to correct fuel injection quantity.

2. The intake pressure sensor directly determines the fuel injection quantity. If there is more air intake and less air intake, the fuel injection quantity cannot be started by unplugging the plug. Of course, the final fuel injection quantity is calculated by computer with reference to the data of other sensors (mainly oxygen sensors).

Others, such as water temperature sensor (which affects fuel injection when the cold car starts) and knock sensor (when the engine vibrates), have a slight but not too great influence.

The function of the throttle position sensor is to calculate the throttle opening data and feed it back to the computer, but it does not really participate in the fuel injection calculation.
