Abstract

A gas powered internal combustion engine in which the gas is provided from pressurized liquid gas in an LPG container and in which the LPG container is rigidly mounted adjacent to the internal combustion engine at a preselected angle to be in conductive heat transfer relationship to the internal combustion engine and in vibration receiving relationship to the internal combustion engine whereby the liquified gas in the LPG container is heated and the effective surface area thereof is increased.

Claims (51)

1. A gas powered internal combustion engine drive arrangement comprising, in combination:

an internal combustion engine for rotating an output shaft for said internal combustion engine in an operating condition thereof;

said output shaft of said internal combustion engine connected to drive a gardening tool;

a mounting bracket rigidly connected to said internal combustion engine for receiving heat and vibration from said internal combustion engine;

a liquified gas storage bottle arrangement having liquified gas therein and gas phase of said liquified gas therein rigidly and removably mounted on said mounting bracket for receiving said heat and vibration therefrom for agitating and heating said liquified gas stored in said liquified gas storage bottle to increase the generation of gas phase therefrom, and said liquified gas storage bottle having an outlet connection.

2. The arrangement defined in claim 1 and further comprising:

a connector connected to said output connection of said liquified gas storage bottle for receiving said gas phase therefrom;

an outlet conduit having a first end connected to said connector for receiving said gas phase from said connector, and a second end;

a pressure regulator mounted on said internal combustion engine for delivering gas phase to said internal combustion engine, and said second end of said outlet conduit connected to said pressure regulator for delivering gas phase to said pressure regulator;

said outlet conduit comprising a flexible hose;

whereby said internal combustion engine receives said gas phase for operation thereof from said pressure regulator and said internal combustion engine generates said heat and said vibration for the condition of said internal combustion engine operating.

3. The arrangement defined in claim 2 wherein:

said liquified gas storage bottle arrangement is mounted at a preselected angle to the horizontal sufficient to increase the surface area of said liquified gas therein.

4. The arrangement defined in claim 3 wherein:

said preselected angle is in the range of 14° and 16°.

5. The arrangement defined in claim 2 and further comprising:

said internal combustion engine has a carburetor;

said pressure regulator is connected to said carburetor.

6. The arrangement defined in claim 1 and further comprising:

a connector connected to said output connection of said liquified gas storage bottle for receiving said gas phase therefrom;

an outlet conduit having a first end connected to said connector and a second end;

a pressure regulator for delivering gas phase to said internal combustion engine, and said second end of said outlet conduit connected to said pressure regulator;

a delivery conduit connected to said pressure regulator and to said internal combustion engine for delivering said gas phase to said internal combustion engine;

said pressure regulator line mounted on said outlet conduit and said second conduit and free of other connection to said internal combustion engine; and,

at least one of said outlet conduit and said second conduit is a flexible hose,

whereby said internal combustion engine receives said gas phase for operation thereof from said pressure regulator and said internal combustion engine generates said heat and said vibration for the condition of said internal combustion engine operating.

7. The arrangement defined in claim 6 wherein:

said outlet conduit is a flexible hose and said delivery conduit is a rigid conduit.

8. The arrangement defined in claim 6 wherein:

said outlet conduit is a rigid conduit and said delivery conduit is a flexible hose.

9. The arrangement defined in claim 6 wherein:

said outlet conduit is a flexible hose and said delivery conduit is a flexible hose.

10. The arrangement defined in claim 6 wherein:

said liquified gas storage bottle arrangement is mounted at a preselected angle to the horizontal sufficient to increase the surface area of said liquified gas therein.

11. The arrangement defined in claim 10 wherein:

said preselected angle is in the range of 14° and 16°.

12. The arrangement defined in claim 6 and further comprising:

said internal combustion engine has a carburetor;

said delivery conduit is connected between said carburetor and said pressure regulator.

13. The arrangement defined in claim 1 and further comprising:

a connector connected to said output connection of said liquified gas storage bottle for receiving gas phase therefrom;

a pressure regulator mounted on said connector for receiving said gas phase therefrom;

a delivery conduit having a first end connected to said pressure regulator and a second end connected to said internal combustion engine;

said delivery conduit comprising a flexible hose.

14. The arrangement defined in claim 13 wherein:

said liquified gas storage bottle arrangement is mounted at a preselected angle to the horizontal sufficient to increase the surface area of said liquified gas therein.

15. The arrangement defined in claim 11 wherein:

said preselected angle is in the range of 14° and 16°.

16. The arrangement defined in claim 13 and further comprising:

said internal combustion engine has a carburetor;

said delivery conduit is connected between said carburetor and said pressure regulator.
