TWO-FUEL GAS-GASOLINE INTERNAL COMBUSTION ENGINE Russian patent published in 1997 - IPC

FIELD: engine engineering. SUBSTANCE: between air filter 18 and gas adapter-mixer 6 of carburetor 15 is air distributing device 19 made up as a hollow spacer with check valve 20 having seat 21 arranged along the axis of the hollow spacer. The valve separates the inner space of the spacer into two interconnected spaces 22 and 23. Distributing device 19 is provided with air branch pipes 24 and 25 used for communication of inner spaces 22 and 23 with turbine compressor. In addition air distributing device 19 is provided with an air-actuated control system made up as cylinder 26 and piston 26 mounted inside it and coupled with the plate of automatic valve 20 through rod 28. The engine is provided with turbine compressor 29 having gas turbine 30 actuated with exhaust gases and compressor 31 for supplying compressed air to the engine. The gas receiving branch pipe of gas turbine 30 is connected with outlet manifold 33 of the engine. Branch pipe 34 serves for discharging exhaust gases to the atmosphere. The gas receiving branch pipe of compressor 31 is connected with air branch pipe 24 through sucking pipe line 35, and the air delivery branch pipe of compressor 31 is connected with air branch pipe 25 of air distributing device 19 through delivery pipe line 36. Outlet manifold 33 is provided with by-pass 37 with bu- passing member 38. The above-piston space of the air- operated cylinder 26 is in communication with sucking branch pipe of compressor 31 through pipe line 39 with adjusting screw 40. Heating air pipe line 36 is coupled from one side with above-diaphragm space of the first stage through balancing pipe 41, and from the other side with above-diaphragm space of the second stage of gas regulator 5 through balancing pipe 42. EFFECT: enhanced efficiency. 1 dwg
