Abstract
The invention relates to a multicylinder internal combustion engine with an engine braking system including intake and exhaust valves and at least one additional brake valve for each cylinder, the exhaust valves opening into an exhaust system. Further a preferably tubular pressure reservoir with a pressure regulating valve is provided, into which braking channels departing from the brake valves are leading, so that a gas exchange between the individual cylinders is possible upon actuation of the brake valves.
