Abstract
A fuel rail for supplying liquified petroleum gas ('LPG') to an internal combustion engine. Fuel supply channel and fuel return channel are aligned generally parallel to one another within fuel rail. LPG flowing through return channel cools LPG flowing through supply channel by vaporization of return fuel. Vaporization is caused by lower pressure in return channel relative to supply channel. Cooling of supply fuel aids in maintaining LPG injected into the engine in a fully liquid state. This results in increased power output, lower toxic emissions, and a reduction in knocking.
