    摘要: A method for operating an internal combustion engine with variable gas exchange control times and with variable control times for the inlet and outlet valves includes, in various operating modes, direct exhaust-gas recirculation by the retarded closing of the outlet valve, exhaust-gas retention by the insertion of a compression and expansion phase with closed gas exchange valves, exhaust-gas filling of the combustion space by the opening of the outlet valve in the gas intake phase, with the inlet valve closed, and/or an apportionment of the combustion action, if appropriate combined with an exhaust emission control measure, to a plurality of working strokes of a working cycle. The various operating modes may be set individually for each combustion space and each working cycle. The method may by used, for example, for gasoline and diesel engines of motor vehicles.
