Abstract
The invention relates to a method and an arrangement for controlling a drive unit (1) including an internal combustion engine (5). The method and arrangement function to provide a switchoff of the engine (5) with less vibration. In the internal combustion engine (5), the air or a mixture of air and fuel is compressed in a combustion chamber (10) while utilizing a compressing device (15) and especially a piston. A supply of fuel is reduced with a switchoff of the engine (5). When switching off the engine (5), a relief of load of the compressing device (15) is initiated in addition to the reduction of the metering of fuel.
