Abstract:
1. An internal combustion engine, including a number of cylinders ( 2 ), an intake tract ( 4 ) connected to the cylinders ( 2 ) for supplying combustion air thereto, a common gas pressure container ( 14 ) in communication with the cylinders, each via an adjustable brake valve ( 15 ) for controlling compressed gas flow out of the cylinders ( 2 ) and into the gas pressure container ( 14 ), an exhaust strand ( 6 ) for discharging exhaust gas from the engine and an outflow line ( 16 ) extending from the common gas pressure container to the exhaust strand ( 6 ), an outflow valve ( 17 ) disposed in the outflow line ( 16 ) for controlling the release of compressed gas from the common pressure container ( 14 ) to the exhaust strand ( 6 ), and a recirculation line ( 18 ) extending from the common pressure container ( 14 ) to the intake tract ( 4 ) of the internal combustion engine and including an adjustable check valve ( 19 ) for controlling the gas recirculation flow from the common pressure container ( 14 ) to the intake tract ( 4 ), and a control unit ( 21 ) for controlling the adjustable brake valves ( 15 ), the outflow valve ( 17 ) and the adjustable check valve ( 19 ) for controlling the pressure in the pressure container ( 14 ) and, as a result, the engine braking power and also internal and external exhaust gas recirculation via the recirculation line ( 18 ).
