ABSTRACT:
A fuel supply system for providing liquified petroleum gas ("LPG") fuel in a liquid state to intake manifold of internal combustion engine, including a fuel supply assembly and a fuel injecting mechanism. Fuel supply assembly includes a fuel rail assembly containing both supply and return channels. Fuel injecting mechanism is in fluid communication with supply and return channels of fuel rail assembly. Injected LPG is maintained liquid through refrigeration both along fuel rail assembly and within fuel injecting mechanism. Return fuel in both fuel rail assembly and fuel injecting mechanism is used to effectively cool supply fuel to a liquid state prior to injection into intake manifold of engine.
