ENGINE 648.961 in MODEL 211
The task of overheating protection is to prevent engine damage caused by thermal overloading.
If the coolant temperature and/or the charge air temperature is too high, the injection quantity is reduced by the CDI control unit according to a performance map.
The following information is processed in the CDI control unit for this purpose:
- Charge air temperature
- Charge air pressure
- Coolant temperature
- Engine speed
- Vehicle speed
If the signal from the coolant temperature sensor is missing, the oil temperature signal from the oil sensor is used (for emergency mode).
