FIELD: engine building.
SUBSTANCE: gas-diesel engine recirculation system includes bypass pipeline (1) with controlled locking element (2). Input of adjustable shutoff element (2) is communicated with internal combustion engine exhaust pipeline (3), and outlet is connected with internal combustion engine inlet pipeline (4). System is equipped with bypass valve (5), cooler-mixer (6), water supply system consisting of nozzle (7), cooling system of exhaust gases (8). Exhaust gas cooling system (8) is independent or included in engine cooling system, also comprises water supply pump (9), water tank (10), engine fuel supply control unit or water injection control unit depending on speed and load operating modes engine.
EFFECT: technical result consists in detonation-free operation of engine and, consequently, improvement of fuel efficiency.
