ABSTRACT:
A vaporized fuel injection system for a combustion engine that includes a fuel vaporization chamber and a two-way valve. The fuel vaporization chamber has a chamber input and a chamber output, and is connected with a fuel source via the chamber input. The fuel vaporization chamber is for vaporizing fuel input to the chamber input and outputting vaporized fuel to the chamber output. The two-way valve has first and second valve inputs and an valve output. The first valve input is connected to the chamber output, and the second valve input is connected to the fuel source. The two-way valve is switchable to allow fuel to flow from only one of the first or second valve inputs to the valve output.
