Abstract
Abstract A fuel conversion system is provided in which a petroleum fraction is circulated past the outside of the cylinders of an internal combustion engine in contact with a cracking catalyst to thereby crack the fuel as a result of the combined action of the catalyst and the heat imparted to the fuel through the cylinder walls, simultaneously providing oxygen and hydrogen to the fuel, circulating the resulting fuel to the interior of the cylinders where it is burned to drive the cylinders' piston.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
80 words
In a method of producing mechanical work by burning a fuel in an internal combustion engine by introducing the fuel into the cylinders and igniting the fuel therein, the improvement which comprises circulating a petroleum fraction capable of being cracked into gasoline past the outside of said cylinders in contact with a cracking catalyst to thereby crack the fraction, providing oxygen and hydrogen to the cracked fraction, and thereafter circulating the resulting cracked fraction to the interior of the cylinders.
Claim 2
Dependent Claim
80 words
In a method of producing mechanical work by burning a fuel in an internal combustion engine by introducing the fuel into the cylinders and igniting the fuel therein, the improvement which comprises circulating a petroleum fraction capable of being cracked into gasoline past the outside of said cylinders in contact with a cracking catalyst to thereby crack the fraction, providing oxygen and hydrogen to the cracked fraction, and thereafter circulating the resulting cracked fraction to the interior of the cylinders.
Claim 3
Dependent Claim
14 words
The process of claim 1 wherein the petroleum fraction is kerosene or gas oil.
Claim 4
Dependent Claim
14 words
The process of claim 1 wherein the hydrogen and oxygen are provided by electrolysis.
Claim 5
Dependent Claim
24 words
The process of claim 1 wherein the cracked fuel is conveyed to a carburetor and from the carburetor to the interior of the cylinders.
Claim 6
Dependent Claim
14 words
The process of claim 1 wherein the cracking catalyst is copper, nickel or cadmium.
Claim 7
Dependent Claim
70 words
In an internal combustion engine comprising a fuel tank, a carburetor, cylinders, and a cooling circuit comprising a radiator communicating with an enclosed space surrounding the exterior surfaces of the cylinders, the improvement which comprises placing said fuel tank in communication with the space surrounding the exterior surfaces of said cylinders, connecting said carburetor with said space, and providing isolating valves in the communication between the radiator and said space.
Claim 8
Dependent Claim
70 words
In an internal combustion engine comprising a fuel tank, a carburetor, cylinders, and a cooling circuit comprising a radiator communicating with an enclosed space surrounding the exterior surfaces of the cylinders, the improvement which comprises placing said fuel tank in communication with the space surrounding the exterior surfaces of said cylinders, connecting said carburetor with said space, and providing isolating valves in the communication between the radiator and said space.
Claim 9
Dependent Claim
16 words
The internal combustion engine of claim 6 further comprising a closed electrolysis unit within said space.
Claim 10
Dependent Claim
56 words
The internal combustion engine of claim 6 wherein said space commumicates with said carburetor through a valve, a second fuel tank communicating with the carburetor through the same valve, said valve being adapted to allow communication to the carburetor to only one of said space and said second fuel tank at any given period of time.
Claim 11
Dependent Claim
91 words
In a method of producing mechanical work by burning a fuel in an internal combustion engine by introducing the fuel into the cylinders and igniting the fuel therein, the improvement which comprises circulating a petroleum fraction capable of being cracked into gasoline past the outside of said cylinders in contact with a cracking catalyst to thereby crack the fraction and thereafter circulating the resulting cracked fraction to the interiors of the cylinders, wherein excess heat is removed from the cracked fuel by circulating a portion of said fuel to a radiator.
Claim 12
Dependent Claim
91 words
In a method of producing mechanical work by burning a fuel in an internal combustion engine by introducing the fuel into the cylinders and igniting the fuel therein, the improvement which comprises circulating a petroleum fraction capable of being cracked into gasoline past the outside of said cylinders in contact with a cracking catalyst to thereby crack the fraction and thereafter circulating the resulting cracked fraction to the interiors of the cylinders, wherein excess heat is removed from the cracked fuel by circulating a portion of said fuel to a radiator.
