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

FIELD: engine engineering. SUBSTANCE: air dispensing device 19 is interposed between air filter 18 and gas adapter-mixer 6 of carburetor 15. The dispensing device is made up as hollow spacer and provided with automatic check valve 20 arranged at the axis of the inner space of the spacer. Seat 21 of the check valve separates the inner space of the spacer into two interconnected spaces 22 and 23. Dispensing device 19 is provided with air branch pipes 24 and 23 with a turbo-compressor. The engine has turbo-compressor 26 provided with gas turbine 27 activated by means of exhaust gases and compressor 28 for supplying compressed air to engine 29. The gas receiving branch pipe of gas turbine 27 is connected with the outlet manifold 30 of engine 29. Turbine 29 is also provided with outlet branch pipe 31 for discharging exhaust gases to the atmosphere. The gas receiving branch pipe of compressor 28 is in communication with air branch pipe 24 through sucking pipe line 32. The air delivery branch pipe of compressor 28 is in communication with air branch pipe 25 of air dispensing device 19 through delivery pipe line 33. Outlet manifold 30 is provided with by-pass 34 having by-passing control member 35. EFFECT: enhanced efficiency. 1 dwg
