FIELD: engine engineering.
SUBSTANCE: device comprises throttle device built in the exhaust gas line and actuated so that counter-pressure is generated upstream of the throttle device in the collected exhaust gas that acts in cooperation with the special braking device built in the engine. The braking device is in cooperation only with one of two outlet valves of the cylinder. The other outlet valve is controlled generally. The braking device has distributing piston built in the valve cross-piece that presses in the direction of the outlet valve by means of control compression chamber provided with pressurized oil and through the additional control compression spring. The control compression chamber is connected with the device for continuous supply of pressurized oil and, depending on the movement or control of valve cross-piece by means of relief valve, blocks or releases pressure.
EFFECT: enhanced efficiency.
