Abstract
In order to be able to implement low loads at high rotational speeds in an internal combustion engine with electromagnetically activated intake valves, one intake valve of a cylinder is operated in the free flying phase, i.e. not held in the open position, and the other intake valve of the cylinder is correspondingly opened for a longer time. Alternatively, the first valve can also be held closed.
