A process for the load-dependent control of the gas exchange valves on a piston internal combustion engine

摘要

A process for the load-dependent control of the gas exchange valves on a piston internal combustion engine, in which the gas exchange valves in each case for the actuation with an electromagnetic actuator, the restoring springs directed against one another by means of a supported armature is provided, which in each case by means of an electrical in the closed position and closing by an electrical opener magnet is maintained in the open position, wherein the movement of the armature from the one position into the other position in each case by means of the current is switched on, in each case, the holding magnet is introduced, characterised in that in the case of partial load in each case at least for the gas induction valve of a cylinder, a reduced opening stroke is effected in that, shortly after the switching-off of the holding current at the closing magnets for the introduction of the opening movement of the closing magnet are, in order to initiate premature closing movement current is supplied with closed again, before the armature the by the force of the cooperating restoring springs has reached a defined rest position and that, in this case, the closing current after recognition of the movement of the armature and / or upon recognition of a certain armature position and / or..
