Abstract
Abstract A power driven wheeled vehicle with a power source consisting of an internal combustion engine, a compressor section, a heat reservoir and driven motor located at the wheels. The said internal combustion engine drives the said compressor section which uses the said engine's exhaust and cooling air as the input source. The said compressor supplies the said reservoir which supplies the said drive motors through a control valve driving the wheels of the said vehicle.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
98 words
A vehicle comprising a frame, axles on said frame connected to wheels, air motors connected to each said axle, said frame defining and forming an essentially air tight enclosure, an air reservoir in said enclosure, an engine and an air compressor in said enclosure, said air compressor being connected to drive air into said reservoir, said engine having an exhaust directed into said compressor, and means to admit air into said enclosure between said reservoir and said frame for directing air to said engine and to said air compressor, and means connecting said reservoir to said air motors.
Claim 2
Dependent Claim
98 words
A vehicle comprising a frame, axles on said frame connected to wheels, air motors connected to each said axle, said frame defining and forming an essentially air tight enclosure, an air reservoir in said enclosure, an engine and an air compressor in said enclosure, said air compressor being connected to drive air into said reservoir, said engine having an exhaust directed into said compressor, and means to admit air into said enclosure between said reservoir and said frame for directing air to said engine and to said air compressor, and means connecting said reservoir to said air motors.
Claim 3
Dependent Claim
33 words
The vehicle recited in claim 1 wherein said vehicle has a ram baffle at the front end for receiving air and directing said air to said means to admit air into said enclosure.
Claim 4
Dependent Claim
25 words
The vehicle recited in claim 1 wherein an inlet is provided to said compressor at the end of said enclosure remote from said ram baffle.
Claim 5
Dependent Claim
57 words
The vehicle recited in claim 3 wherein each said axle has a brake thereon and said brake has cooling means and said cooling means is disposed in the flow path of air from said ram baffle to said inlet to said compressor whereby each of said brakes is cooled and the heated air directed into said compressor.
Claim 6
Independent Claim
169 words
The method of converting heat energy from the combustion of hydrocarbon fuels in a conversion system including an internal combustion engine and a fluid compressor to mechanical work comprising the steps of: a. heating combustion air introduced into the internal combustion engine by passing said air initially over heat producing elements in said system including said I.C. engine and compressor, b. combining a portion of said heated air with fuel and effecting combustion of said combined mixture in said I.C. engine, c. exhausting the products of combustion from the I.C. engine into the intake of the fluid compressor, d. simultaneously introducing a further portion of said heated air into said compressor, e. utilizing the mechanical output of said I.C. engine to drive said fluid compressor to compress said heated air and said products of combustion, f. exhausting the output from said compressor into a holding reservoir and g. exhausting the compressed contents from said reservoir into mechanical conversion means to convert the available latent energy into useful mechanical work.
