SUPPLY SYSTEM OF INTERNAL COMBUSTION GAS ENGINE Russian patent published in 2004 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention relates to internal combustion engines operating on liquefied petroleum gas. Proposed supply system contains reducer-evaporator consisting of first and second stage spaces, channel to place spaces in communication, and outlet gas channel with meter. First and second stage communicating channel of reducer-evaporator with second stage valve is made at level not higher than lower edge of first stage space, and outlet gas channel is arranged at level not higher than lower edge of second stage space of reduced-evaporator, according to its orientation when mounting on vehicle. Outlet gas channel of reducer-evaporator has variable section widening to outlet, and meter is made in critical section of outlet gas channel. Gas condensate is removed by flow of gas passing into engine. Thanks to it possibility is provided of dispensing with drain branch pipes with plugs without affecting starting and service characteristics of vehicle and dispensing with necessity of manual removal of condensate in operation of LPG vehicles. EFFECT: improved design of gas outlet channel os reducer- evaporator, efficiency of engine supply system as to stability, economy and no adverse effect on environment. 2 cl, 1 dwg
