METHOD AND DEVICE FOR PROTECTING DUAL MASS FLYWHEEL OF VEHICLE

A method for protecting a dual mass flywheel (DMF) of a vehicle includes comparing, by a controller, an RPM of a vehicle engine with a threshold value, which is set to avoid a resonance point of the DMF. If the RPM of the engine is less than the threshold value, fuel injection into the engine is shu...

Beschreibung
Zusammenfassung:	A method for protecting a dual mass flywheel (DMF) of a vehicle includes comparing, by a controller, an RPM of a vehicle engine with a threshold value, which is set to avoid a resonance point of the DMF. If the RPM of the engine is less than the threshold value, fuel injection into the engine is shut off to stop the engine by the controller. Whether a fuel injection condition to start the engine is met is determined after the fuel injection is shut off by the controller. If the fuel injection condition is met, the fuel injection into the engine is resumed to start the engine by the controller.
