## 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

### Claim 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, and said internal combustion engine generating heat and vibration for the condition of said internal combustion engine in the operating condition thereof;
said output shaft of said internal combustion engine connected to drive a preselected powered device;
a mounting bracket rigidly connected to said internal combustion engine for receiving heat and vibration from said internal combustion engine, and said mounting bracket having walls defining a first predetermined geometric configuration;
