DEVICE TO SUPPLY GASEOUS FUEL INTO INTERNAL COMBUSTION ENGINE Russian patent published in 2003 - IPC

FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: proposed device contains carburetor with air flow rate diffuser, carburetor throttle valve, reducer-evaporator with high and low pressure spaces and chamber with control diaphragm. Constant pressure regulator and additional chamber are provided. Additional chamber is divided by spring-loaded diaphragm into overdiaphragm space connected by channel with low pressure over-diaphragm space of reducer and under-diaphragm space with valve connected through control jet with lowpressure over-diaphragm space and control diaphragm under-diaphragm space. Nozzle provides continuous delivery gaseous fuel. Invention makes it possible to obtain maximum load at fully opened throttle valves and provide continuous delivery of gaseous fuel engine intake manifold. EFFECT: reduced power losses at transition to maximum loads. 1 dwg
