Method for operating an internal combustion engine

摘要

The present invention relates to a method for operating a multi-cylinder internal combustion engine having gas exchange valves which are variably adjustable with respect to the valve opening characteristics either directly electromag-netically or by means of an electrohydraulic valve actuation system which includes several electromagnetic valves. For adaptation of all gas exchange valves to a desired valve opening characteristics, the electromagnetic valves are operated cylinder-selectively in the operation of the internal combustion engine by means of variable actuating voltages and/or actuating currents.
