Title:
VAPORIZED FUEL INJECTION SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO2004092569
Kind Code:
A3
Abstract:
A vaporized fuel injection system for a combustion engine 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 a 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.
