METHOD OF OPERATION OF INTERNAL COMBUSTION ENGINE AND INTERNAL COMBUSTION ENGINE Russian patent published in 1995 - IPC

FIELD: engine engineering. SUBSTANCE: cyclic supply of additional air is changed depending on torque and speed of rotation of the crankshaft. The cyclic supply is changed after evaporation before mixing with additional air. When the engine is in operation the cyclic supply of additional air is decreased with increasing speed of rotation of the crankshaft up to achieving maximum torque, and with further increasing of speed of rotation the additional air supply is increased. When the engine is in operation the value of cyclic supply of fuel is decreased with decreasing torque of the engine. The pressure drop between fuel-air mixture and fresh air at the instance of the beginning of mixture delivering is maintained constant for all operational conditions. Branch pipe 12 for supplying air to mixer 11 is provided with controlled throttle 21. Device 16 for changing cyclic supply of fuel is constructed as controlled valving member 22 and mounted inside pipe line 19 which connect evaporator 10 with mixer 11. Spring loaded stop valve 25 is mounted inside passageway 20 which connects outlet port 15 of compressor 13 with combustion chamber 8. EFFECT: enhanced efficiency. 5 cl, 4 dwg
