Abstract
A method for operating a reciprocating internal combustion engine in an engine braking mode includes, in a working cycle of the engine braking mode, a first outlet valve of a first cylinder is closed for a first time, then opened for a first time, and subsequently closed for a second time, and then opened for a second time, in order to thereby discharge gas that has been compressed in the first cylinder from the first cylinder by a cylinder piston. The outlet valve is held open after the first opening and prior to the second closing long enough for the cylinder to be filled with gas that flows out of a second cylinder via at least one outlet channel, where when the engine braking mode is activated, at least one camshaft for activating at least one gas exchange valve of the reciprocating internal combustion engine is adjusted.
