Abstract (en)
[origin: WO2012072878A1] The present invention relates to an arrangement and a method of operating a gas exchange valve of an internal combustion engine. The present invention discusses the operating of a gas exchange valve (102) of an internal combustion engine by means of a pressure medium actuator (10) with help of control means (80, 82, 84; 90, 92, 94) in relation to one or more engine characteristics by, when opening the gas exchange valve (102), selecting one or more opening pressure chambers (40, 42, 44) to be connected to a pressure medium supply (70) for adjusting a force opening the gas exchange valve (102), and when closing the gas exchange valve (102), connecting the opening pressure chambers (40, 42, 44) to a pressure outlet (60).The present invention also relates also to a novel cylinder head and a new method of upgrading an internal combustion engine.
