What are the car engine sensors, where are they located?

1. The crankshaft car engine sensor accurately calculates the position of the crankshaft, which is used for fuel injection timing, fuel injection quantity and speed calculation.

2. When the camshaft car engine sensor judges the cylinder and the crankshaft car engine sensor fails, it is used to go home lame (temporary operation).
3. The intake air temperature car engine sensor measures the intake air temperature, corrects the fuel injection quantity and timing, and protects against overheating.
4. The boost pressure car engine sensor monitors the intake air pressure, calculates the intake air volume together with the intake air temperature, and integrates it with the intake air temperature.
5. The cooling water temperature car engine sensor measures the cooling water temperature, which is used for cold start, target idle speed calculation, etc. It is also used to correct the fuel injection advance angle and overheat protection.
6. The common rail pressure car engine sensor measures the fuel pressure in the common rail pipe to ensure stable oil pressure control.
7. The accelerator position car engine sensor sends the driver's intention to the controller ECU.
8. The vehicle speed car engine sensor provides the vehicle speed signal to the ECU for vehicle drive control, which is provided by the vehicle.
9. The atmospheric pressure car engine sensor is used to correct the fuel injection control parameters at different altitudes and is integrated in the ECU.
There are also car engine sensors for cylinder pressure, car engine sensors for knocking, and some car engine sensors for monitoring post-processing CH and NO emissions in the future. In addition, the bench test needs to measure parameters under instantaneous conditions. The company just bought one a few days ago. 10 W a few, very expensive.
