Multiple cylinder internal combustion engine

本发明涉及一种至少具有一个气缸列的多缸内燃机，每个气缸列有一个气缸盖外壳(24)，其中布置有进气和排气阀门(26，28)，它们经过控制机构(38，40)根据曲轴(12)的旋转位置而向气缸输给燃气并将燃烧废气经排气设备(36)而排出。设有机构(44′)，用来实现至少两个布置在一个气缸列里的气缸的各不相同的排气阀门冲程度化，这种情况就减少了这种排气阀门(28)的开启重叠相位，其中两个气缸中的一个气缸的进气阀(26)和排气阀(28)本身就处于开启重叠相位。因此尤其是对于具有90°弯曲的曲轴的一个V8发动机来说，就实现了用新鲜气体一致地充满气缸。 A multi-cylinder internal combustion engine with at least one cylinder row is equipped with a cylinder head housing containing intake and exhaust valves that feed combustion air to the cylinders and release combustion exhaust gases through an exhaust system via control devices in dependence of the position of the crankshaft. Devices for generating differing exhaust valve lift progressions of at least two cylinders arranged in one cylinder row are incorporated to reduce overlapping opening phases of these exhaust valves. The intake valve and the exhaust valve of one of the two cylinders are themselves in an overlapping opening phase. Thereby, a uniform filling rate of the cylinders with new gas is achieved, particularly on a V-8 engine with a 90°-bent crankshaft.
