Method for influencing the mixture formation and charging movement in a cylinder of a piston internal combustion engine with externally applied ignition

摘要

A method of influencing the mixture formation and charge movement in the cylinders of a piston internal combustion engine, having at least one gas intake valve and at least one gas outlet valve per cylinder. Each of the valves is provided with a fully variable, preferably electrimagnetic, valve drive and is controllable via an electronic control device that is configured such that within predetermined speed ranges and/or for predetermined load conditions, at least some of the gas intake valves and/or the gas outlet valves can be moved, respectively in dependence on the piston stroke, with a stroke course that is variable, relative to the opening and closing moments and/or the opening time, the opening width and/or the opening duration and/or the movement speed.
