Verfahren zum laststeuernden Betrieb elektromagnetisch betätigter Einlaßventile einer Brennkraftmaschine

摘要

The invention relates to a method for the load-controlled operation of electromagnetically actuated inlet valves of an internal combustion engine. The aim of the invention is to obtain low loads for high rotational speeds in an internal combustion engine with electromagnetically actuated inlet valves. To this end, one inlet valve of a cylinder is operated in the free-flight phase, i.e. not kept in the open position, and the other inlet valve of the cylinder is kept open longer accordingly. Alternatively, the first valve can also be kept closed.
