PISTON ENGINE AND ASSOCIATED OPERATING METHOD

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 recircula...

Beschreibung
Zusammenfassung:	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. 本发明涉及种用于运行具有内部燃烧过程的活塞式发动机、优选奥托发动机的方法，其中，对于每个燃烧室，至少个进气阀(1，2)提前地或滞后地关闭，其中，可执行废气再循环。如果对于每个燃烧室设置有至少两个进气阀(1，2)，所述进气阀至少在所述废气再循环中以不同的最大行程(Hmax，Hmax)打开，则可实现提高的废气再循环率。
