Zusammenfassung:A locking mechanism ( 6 ) is provided to block the internal combustion engine ( 1 ) at prepositioned cranking angle after shutting down. Preferably, the crankshaft of the engine is positioned at a crankshaft angle that is favorable for cranking. Prepositioning of the crankshaft angle results in a lower first compression torque and therefore increases kinetic energy stored in the crankshaft lumped inertia. The required maximum torque of the cranking aid ( 2 a , 2 b , 2 c) can therefore be reduced.
