METHOD OF SUPPLY OF INTERNAL COMBUSTION ENGINE Russian patent published in 1997 - IPC

FIELD: mechanical engineering; supply systems of internal combustion engines. SUBSTANCE: gaseous fuel in liquid phase is taken form gaseous fuel supply source and is delivered into engine supply system. Gaseous fuel is subjected to cleaning in multistage filter and than is heated in evaporator to converter it into new consistent state, is reduced and delivered under pressure into intake manifold thus providing effect of supercharging and complete combustion of double fuel mixture. At idling, gas is supplied into idle system of carburetor without liquid fuel which considerably reduces toxicity of exhaust gases at idling. Sharp reduction of toxicity of exhaust gases and considerable (up to 50%) economy of liquid fuel is provided owing to enrichment of liquid fuel-air mixture and delivering the mixture into intake manifold through atomizer in minimum amounts sufficient for starting and operating the engine. EFFECT: reduced toxicity of exhaust gases, cut down consumption of fuel. 4 cl, 4 dwg
