The ECU in the diesel engine is a central control unit. The ECU controls the diesel oil pump (pump oil), the common rail pipe (storage and balanced diesel pressure), and the injector (atomizes the diesel and mixes it with the air in the combustion chamber. The stroke can be Burning fuel gas), they are injected into the combustion chamber according to a certain pressure, time, and firing rate to achieve precise fuel injection effects, and through accurate calculations, the fuel energy consumption can be lower, the fuel utilization rate is higher, and the emissions are more environmentally friendly. , this advanced control unit replaces the traditional mechanical fuel injection pump fuel supply method.
The ECU of the electronically controlled diesel engine mainly calculates the fuel injection amount based on signals from the throttle position sensor, intake air temperature sensor, and intake air pressure sensor.
The sensors and functions used in electronically controlled diesel engines are as follows:
1. The crankshaft sensor accurately calculates the crankshaft position and is used to calculate the fuel injection time, fuel injection amount and speed.
2. The camshaft sensor is used to lame home (temporary operation) when the cylinder and crankshaft sensors fail.
3. The intake air temperature sensor measures the intake air temperature, corrects the injection amount and injection timing, and provides overheating protection. The boost pressure sensor monitors the intake air pressure, calculates the intake air amount together with the intake air temperature, and is integrated with the intake air temperature. .
4. The cooling water temperature sensor measures the cooling water temperature and is used for cold starting, target idle speed calculation, etc., and is also used to correct the injection advance angle, overheating protection, etc.
5. The common rail pressure sensor measures the fuel pressure in the common rail pipe to ensure stable oil pressure control.
6. The accelerator position sensor sends the driver's intention to the controller ECU.
7. The vehicle speed sensor provides the vehicle speed signal to the ECU for vehicle drive control, which is provided by the entire vehicle.
8. The atmospheric pressure sensor is used to correct injection control parameters at different altitudes and is integrated in the ECU.
