Abstract
A fuel injector for injecting liquified petroleum gas ("LPG") fuel into an internal combustion engine in a fully liquid state. Fuel injector includes a housing assembly having fuel supply and return channels. At least a portion of the return channel is adjacent to the supply channel, with the fuel in the return channel flowing countercurrent to fuel in the supply channel. Supply fuel in the supply channel is cooled by vaporization of return fuel in the return channel. This cooling aids in maintaining LPG in a fully liquid state during injection, resulting in improved engine performance.
