Abstract
A desired gradual stopping position of a piston in at least one cylinder of an internal combustion engine can be attained very accurately and simply by closing the gas exhaust valves of one or more cylinders of an internal combustion engine for one or more time segments after the ignition has been turned off, the beginning and the end of each valve closing segment being controlled so that the crankshaft comes to a stop in the desired stopping position.
