ABSTRACT:
The invention is directed to a method and an arrangement for controlling an internal combustion engine (20) which achieve an optimal efficiency in different operating states. An opening time of an inlet valve (5) of a cylinder (1) of the engine (20) is variably adjusted. Depending upon an operating variable, especially the engine speed, two operating states of the engine (20) are distinguished. In a first operating state, during an intake operation, an opening of the inlet valve (5) is delayed. In a second operating state, a closing of the inlet valve is delayed and carried out during a compression operation.
