Method for venting control pressure line between hydraulically actuated coupling element of internal combustion engine, involves electrical activation of hydraulic valve whereby pressure surge is produced in control pressure line

摘要

Method involves electrical activation of hydraulic valve (3) during a first operating mode of internal combustion engine in such a way that its working connection (A) and pressure connection (P) are temporarily connected to one another within one or more short-time intervals with unchanged control state of coupling element (13) for producing a pressure surge in control pressure line (6).
