In a method for operating a diesel engine having a cylinder, a piston which is guided in a longitudinally displaceable manner oscillating between an upper dead center position and a lower dead center position in the cylinder, and an injector having an injector valve for the injection of a fuel quantity into the cylinder, in a compression cycle delimited by the movement of the piston from the lower dead center position to the upper dead center position, combustion air is compressed. In a working cycle delimited by the movement of the piston from the upper dead center position to the lower dead center position, the injection of the fuel quantity occurs. In all operating states the injection begins after the upper dead center position, the injector valve being abruptly opened.

A device for recycling exhaust gases from an internal combustion engine via an exhaust gas line in its intake area is equipped with an exhaust gas valve that is positioned within a valve chamber and closes off or opens up the connection to a combustion chamber of an internal combustion engine. A valve actuating mechanism is located within the valve chamber. The valve chamber is equipped with at least one cooling channel.
