Abstract (en)
[origin: EP1457645A1] The valve opens a certain crankshaft angle (E01). A build-up described by a crankshaft angle difference (EOF) adds onto a global maximum. In this position, the valve is kept pressed out at a degree of crankshaft angle (EHub1). After this, the valve is partly closed again, i.e. the valve stroke drops to a local 'extremum' (EHub2) reached at a specific point (ES1).
