Abstract

The invention relates to control of a multi-cylinder internal combustion engine, with individually controllable inlet valves, whereby each cylinder of the multi-cylinder internal combustion engine has at least one dedicated inlet valve and the inlet valves, of at least two cylinders, are controlled in such a way that the at least two cylinders produce differing power outputs.
