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.
Claims10
A fuel supply system for providing liquified petroleum gas fuel to an internal combustion engine, the engine having an intake manifold, said fuel supply system comprising:
- a fuel supply assembly including a fuel rail assembly having a first fuel supply channel and a first fuel return channel, the fuel rail assembly having first means for cooling fuel flowing through the first supply channel;
- and
- means for injecting fuel, the injecting means having a second fuel supply channel and a second fuel return channel, the second fuel supply and return channels being in operable fluid communication with the first fuel supply and return channels, respectively, the fuel injecting means having second means for cooling fuel prior to injection into the intake manifold.
