GASEOUS FUEL SUPPLY SYSTEM

摘要

mechanical engineering; engine. SUBSTANCE: proposed gaseous fuel supply system has gas bottle, gas pipeline with main-line gas valve, and gas-flow governor. The latter has four spaces first of which communicates with line gas valve, second one separated from first space by governor valve is placed in communication with injector. Valve of governor is coupled with rod of two diaphragms dividing governor housing into third and fourth spaces communicating with atmosphere and intake manifold of engine. Bypass Channel with adjustable throttle is made in governor housing. Throttle consists of housing with one axial channel and with at least one radial channel. It has also adjusting screw installed in axial channel which communicates with first space of governor. Radial channel communicates with second space pf governor. If natural compressed gas is used to supply engine, system can be additionally furnished with high-pressure regulator and filter arranged between main-line gas valve and gas-flow governor. If liquefied oil gas is used, system can be furnished additionally with tubular gas evaporator. EFFECT: improved efficiency of system at idling. 3 cl, 4 dwg
