Abstract
Abstract This disclosure relates to an adaptation of a conventional internal combustion engine wherein the customary energy losses in the form of heat are greatly reduced by the conversion of the heat into a power source for other cylinders of the engine. The engine includes plural cylinders of which certain cylinders are conventional internal combustion cylinders and there being a heated gas cylinder and a gas pumping cylinder whereby a gas may be heated by means of the heat loss generally occuring with respect to the internal combustion cylinder and this heated gas may be utilized to produce work in the heated gas cylinder, after which the gas is pumped back into the system by the pumping cylinder. The gas is preferably a combustible gas whereby gas which escapes past the pistons of the heated gas cylinder and the pumping cylinder into the customary crank case of the engine may be delivered into the internal combustion cylinder for burning therein.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
186 words
A combined internal combustion and heat engine comprising engine components including cylinder block means defining a plurality of cylinders and a heat exchange jacket surrounding said cylinders, said cylinders including at least one internal combustion cylinder, at least one heated gas cylinder and at least one gas pumping cylinder, an energy supply system for delivering a combustible mixture to said internal combustion cylinder, exhaust means for receiving hot exhaust gases from said internal combustion cylinder, first conduit means for directing heated gases from said heat exchanger jacket to said heated gas cylinder, second conduit means for directing gases from said heated gas cylinder to said pumping cylinder, and third conduit means for directing gases under pressure from said pumping cylinder back into said heat exchange jacket for reheating and recirculation, each of said cylinders including a piston, and coupling means connected to said pistons for simultaneous reciprocation of all of said pistons in constant timed phased relation, and said second conduit means including a gas cooler for making more dense expanded gases passing from said heated gas cylinder prior to passage thereof into said pumping cylinder.
Claim 2
Dependent Claim
186 words
A combined internal combustion and heat engine comprising engine components including cylinder block means defining a plurality of cylinders and a heat exchange jacket surrounding said cylinders, said cylinders including at least one internal combustion cylinder, at least one heated gas cylinder and at least one gas pumping cylinder, an energy supply system for delivering a combustible mixture to said internal combustion cylinder, exhaust means for receiving hot exhaust gases from said internal combustion cylinder, first conduit means for directing heated gases from said heat exchanger jacket to said heated gas cylinder, second conduit means for directing gases from said heated gas cylinder to said pumping cylinder, and third conduit means for directing gases under pressure from said pumping cylinder back into said heat exchange jacket for reheating and recirculation, each of said cylinders including a piston, and coupling means connected to said pistons for simultaneous reciprocation of all of said pistons in constant timed phased relation, and said second conduit means including a gas cooler for making more dense expanded gases passing from said heated gas cylinder prior to passage thereof into said pumping cylinder.
