TWO-FUEL INTERNAL COMBUSTION ENGINE WITH GAS-TURBINE SUPERCHARGING Russian patent published in 1995 - IPC

FIELD: engine engineering. SUBSTANCE: air distributing unit is mounted above the gas adapter- mixer. The distributing unit is constructed as a separated air cap having branch pipes. An automatic check valve is received horizontally in one of the branch pipes along its axis. The seat of the valve separates the internal space of the cap from the internal space of the intermediate branch pipe. The engine is provided with a turbo-compressor which comprises gas turbine, which is set in operation by exhaust gases, and compressor for supplying compressed air into the engine. The gas receiving branch pipe of the gas turbine is connected to the outlet manifold of the engine. The gas turbine has also the outlet branch pipe for discharging exhaust gases. The air receiving branch pipe of the compressor is connected with an air filter through the suction pipe line, intermediate branch pipe, and main air pipe line. The air delivery branch pipe of the compressor is connected with the air branch pipe of the air distributing unit through the delivery pipe line. The outlet manifold is provided with a by-passing pipe line having the by-pass throttle member. EFFECT: enhanced efficiency. 1 dwg
