Abstract (en)
[origin: WO2015086121A1] The invention relates to a method for operating an internal combustion piston engine, preferably a spark-ignition engine. In said method, at least one intake valve (1, 2) per combustion chamber is closed prematurely or with a delay, and exhaust gas can be recirculated. A higher exhaust gas recirculation rate can be set when at least two intake valves (1, 2) are provided for each combustion chamber, said intake valves (1, 2) being opened with different maximum lifts (HmaxI, HmaxII) at least during exhaust gas recirculation.
