Einrichtung zur Steuerung des Restgasgehaltes von Zylindern einer Verbrennungskraftmaschine

摘要

The invention relates to a device for controlling the residual gas content of individual cylinders of an internal combustion engine having a mechanically fully variable valve train and throttle-free load control, and particularly a mechanically rigid valve train on the exhaust side, wherein an exhaust camshaft (1) has an asymmetrical arrangement of cams (2), wherein the cams (2) of individual special cylinders on the exhaust camshaft (1) have different cam structures (3) in order to adjust the residual gas content and are provided rotatably such that an exhaust spread (5) is reduced for cylinders having too high a residual gas content, or that an exhaust opening time of the individual cylinders can be adjusted such that the same quantity of residual gas is obtained in all cylinders.
