Abstract
Abstract An air and fuel system for carburetor and fuel injection engines that regulates the temperature of air and fuel that is mixed in the carburetor or fuel injector prior to introduction to the cylinders of the engine. A heater and associated filter located at the air intake side of the carburetor are activated by circulating heated fluid (coolant) contained within the engine cooling system. The coolant passes through the heater and an isolated chamber or conductor and the fuel line passes inside the coolant line within the heater surroundings so that air and fuel can be temperature regulated. Valves in the fuel line allow for proper mixture of air and fuel. A filter is sized to fit inside or outside the heater, and the heater and filter are encompassed by a cover to hold the components together. Oxygen is introduced to the system to reduce air pollution, and oxygen and fuel vapors are combined prior to entering the combustion chamber to create a high explosive fuel that burns efficiently and thereby reduces air pollution.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
195 words
An air and fuel heating and regulating system for use with a fluid cooled internal combustion engine having a fuel feeding device, a filter, a fuel supply, a fuel pump, a fuel dispensing device, a cooling system and one or more fuel lines, and one or more combustion chambers, the system comprising: a preheater positioned adjacent the fuel feeding device and the filter and having a housing within which is formed a coolant line connected within the cooling system; fuel flow control means connected with the fuel pump, fuel line, and fuel feeding device, the fuel lines extending into and through the preheater housing coolant line and on to the fuel feeding device; fuel line valve means regulating the quantity of fuel introduced into the fuel lines extending into and through the preheater housing; coolant temperature control means connected with the cooling system regulating the flow of coolant through the preheater coolant line to control the temperature of the preheater; and pure oxygen supply means directing pure oxygen flow through the fuel flow and into the fuel dispensing device to mix with the fuel prior to the introduction to the one or more combustion chambers.
Claim 2
Dependent Claim
195 words
An air and fuel heating and regulating system for use with a fluid cooled internal combustion engine having a fuel feeding device, a filter, a fuel supply, a fuel pump, a fuel dispensing device, a cooling system and one or more fuel lines, and one or more combustion chambers, the system comprising: a preheater positioned adjacent the fuel feeding device and the filter and having a housing within which is formed a coolant line connected within the cooling system; fuel flow control means connected with the fuel pump, fuel line, and fuel feeding device, the fuel lines extending into and through the preheater housing coolant line and on to the fuel feeding device; fuel line valve means regulating the quantity of fuel introduced into the fuel lines extending into and through the preheater housing; coolant temperature control means connected with the cooling system regulating the flow of coolant through the preheater coolant line to control the temperature of the preheater; and pure oxygen supply means directing pure oxygen flow through the fuel flow and into the fuel dispensing device to mix with the fuel prior to the introduction to the one or more combustion chambers.
