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.
Claims38
A vaporized fuel injection system for a combustion engine, said system comprising:
- a fuel vaporization chamber having a first input and a first output, and connected with a fuel source via said first input, said fuel vaporization chamber vaporizing fuel input to said first input and outputting vaporized fuel to said first output;
- and
- a two-way valve having first and second valve inputs and an valve output, said first valve input connected to said first output of said fuel vaporization chamber and said second valve input connected to said fuel source, said two-way valve being switchable to allow fuel to flow from only one of the first or second valve inputs to said valve output.
A method for heating up fuel to high-temperature, high-pressure gaseous state for injection into a combustion engine, the combustion engine including a combustion chamber, a fuel source and a vaporization chamber, said method comprising steps of:
- heating said vaporization chamber;
- when a temperature of said vaporization chamber reaches a predetermined temperature value, allowing fuel to flow into said vaporization chamber from said fuel source;
- and
- when a pressure of said vaporization chamber reaches a predetermined pressure value, allowing fuel to flow from said vaporization chamber to said combustion chamber.
A vaporized fuel injection system comprising:
- a fuel vaporization chamber means for storing fuel to be heated;
- a first flow-controlling means for controlling fuel flowing into said chamber;
- a second flow-controlling means for controlling heated-up gaseous fuel flowing out of said chamber;
- and
- a heating means for heating up fuel in said chamber;
- wherein fuel in said fuel vaporization chamber means is heated up to a gaseous state and is fed to a combustion engine combustion chamber under control of said first and second flow-controlling means;
- wherein said first flow-controlling means controls fuel to flow into said fuel vaporization chamber means when a current temperature of said fuel vaporization chamber means meets or exceeds a predetermined temperature;
- and
- wherein said second flow-controlling means controls heated-up gaseous fuel flowing out of said fuel vaporization chamber means when current pressure of said fuel vaporization chamber means meets or exceeds a predetermined pressure.
