GF07.61-P-4027V Overheating/Pinging Protection, Function







The task of the overheating/pinging protection is to prevent engine damage as a result of excessive thermal overload and overheating damage of the catalytic converters.

The heat output by the cooling system into the environment is mainly dependent on the fan speed, vehicle speed, outside temperature and coolant temperature.

The heat and engine output generated from it in the cooling system by combustion must be restricted so that the maximum permissible coolant temperature is not exceeded.

Here, the throttle valve is no longer fully opened. The air mass drops accordingly and less fuel is injected.
