Controlling internal combustion engine fuel injection valve involves controlling valve for closing movement during further injection so valve needle adopts stroke position different from null position

摘要

The method involves following a first injection with at least one second injection. The injection valve is controlled for a closing movement during the further injection so that the valve needle adopts a stroke position (H3) different from the null position (0). The valve needle is returned to the null position, in which a valve closure body is in contact with a valve seat surface, after the end of a further injection.
