The EFI diesel engine has an intake sensor and a throttle sensor. Which sensors determine its fuel supply? I have seen some people say that it is determined by speed, which is very acceptable.

The vehicle speed, intake temperature and throttle position sensors are comprehensively controlled by ECU. See the following sensor functions.

1. Crankshaft sensor accurately calculates crankshaft position, which is used to calculate injection time, injection quantity and rotation speed.

2. It is used for temporary operation when the camshaft sensor judges the fault of the cylinder and crankshaft sensor.

3. The air temperature sensor measures the intake temperature, corrects the fuel injection quantity and timing, monitors the intake pressure with the overheat protection booster pressure sensor, and calculates the intake volume together with the intake temperature, which is combined with the intake temperature.

4. The cooling water temperature sensor measures the cooling water temperature for cold start and target idle speed calculation. At the same time, it is also used to correct the injection advance angle and overheat protection.

5. The * * * rail pressure sensor measures the fuel pressure in the * * * rail pipe to ensure the stability of oil pressure control.

6. The throttle position sensor sends the driver's intention to the controller ECU.

7. The vehicle speed sensor provides the ECU with the vehicle speed signal for vehicle drive control, which is provided by the vehicle.

8. The atmospheric pressure sensor is used to correct the fuel injection control parameters at different altitudes and is integrated in the ECU.
