GASEOUS FUEL SUPPLY SYSTEM FOR MULTICYLINDER INTERNAL COMBUSTION ENGINE Russian patent published in 1994 - IPC

FIELD: gaseous fuel supply system for multicylinder internal combustion engines of transport facilities. SUBSTANCE: system has carburettor with diffuser, air filter and throttle plate fitted on the intake manifold. Connected to carburettor is gas flow rate reducer-regulator provided with small, large and additional diaphragms which form high-pressure chamber, low-pressure (control pressure) chamber, balancing pressure chamber and correcting pressure chamber. Inlet of high-pressure chamber is connected via valve with the bottle and its outlet is connected via jets with intake branch pipes of each cylinder. Low-pressure (control pressure) chamber is brought in communication with diffuser neck. Balancing pressure chamber is brought in communication with carburettor chamber after air filter and correcting pressure chamber is brought in comunication with after-throttle valve chamber of carburettor. Diameters of small and correcting diaphragms are equal to each other. EFFECT: enhanced efficiency. 1 dwg
