Modification to an internal combustion engine to reduce both fuel consumption and air pollutants

Claim 2

In combination with a standard internal combustion engine a means for reducing the expulsion of air pollutants while maintaining fuel economy and safe usage of a supplemental oxygen supply which comprises a pressurized oxygen supply; a means for reducing the oxygen pressure; means for conducting such oxygen to a safety valve; means for opening and closing said safety valve independently in response to both the engine ignition system and a parameter responsive to both engine activation and shut down; means for further conducting said oxygen to a regulator means; said regulator means which supplies a variable volume of oxygen dependent on the needs of the engine; means of conducting said oxygen to the throat of a modified carburetor; said modified carburetor equipped with a means for restricting flow of atmospheric gases into said carburetor; said modified carburetor equipped with a means for restricting fuel flow within same said modified carburetor.

Claim 3

The invention of claim 1 wherein said safety valve is opened or closed independently in response to both the engine ignition and one or more engine parameters selected from oil pressure; manifold vacuum; crankshaft, camshaft or distributor shaft rotation; pulleys, belts or gears associated with crankshaft, camshaft or distributor shaft rotation; or electrical stimulus associated with distributor operation.

Claim 4

The invention of claim 2 wherein said safety valve opens or closes independently in response to both the engine ignition and the engine oil pressure.

Claim 5

The invention of claim 1 wherein said regulator means which supplies a variable supply of oxygen is open or closed in response to changes in the accelerator pedal position, carburetor butterfly valve rotation, manifold vacuum pressure or distributor rotation.

Claim 6

The invention of claim 1 wherein said means for restricting fuel flow within said modified carburetor is by reduction in the size of the fuel ports, reduction in the size of the fuel jets, shortening of the stroke of the carburetor accelerator pump linkage or a combination of two or more of the reduction in the size of fuel ports, reduction in the size of the fuel jets and a shortening of the stroke of the carburetor accelerator pump.

Claim 7

The invention of claim 1 wherein said safety valve is opened or closed independently in response to both the engine ignition and one or more engine parameters selected from oil pressure; manifold vacuum; crankshaft, camshaft or distributor shaft rotation; pulleys, belts or gears associated with crankshaft, camshaft or distributor shaft rotation; or electrical stimulus associated with distributor operation; and said regulator means which supplies a variable supply of oxygen is open or closed in response to changes in either the accelerator pedal position, carburetor butterfly valve rotation, manifold vacuum pressure or distributor rotation; and said means for restricting fuel flow within said modified carburetor is by reduction in the size of the fuel ports, reduction in the size of the fuel jets, shortening of the stroke of the carburetor accelerator pump linkage or a combination of two or more of the reduction in the size of the fuel ports, reduction in the size of the fuel jets and a shortening of the stroke of the carburetor accelerator pump.

Claim 8

The invention of claim 1 wherein said safety valve opens or closes independently in response to both the engine ignition and the engine oil pressure; and said regulator means is connected to the automobile accelerator pedal and opens and closes as said accelerator pedal is depressed and released respectfully; and said modified carburetor is equipped with reduced fuel ports and fuel jets and said means for restricting the flow of atmospheric gases into said carburetor is a plug in the intake port of an air cleaner attached to said carburetor.

Claim 9

In combination with a standard internal combustion engine a means for reducing the expulsion of air pollutants while maintaining fuel economy and safe usage of a supplemental oxygen supply which comprises a pressurized oxygen supply; a means for reducing the oxygen pressure; means for conducting such oxygen to a safety valve; means for opening and closing said safety valve independently in response to both the engine ignition system and a parameter responsive to both engine activation and shut down; means for further conducting said oxygen to a regulator means; said regulator means which supplies a variable volume of oxygen dependent on the needs of the engine; means of conducting said oxygen to the throat of a modified carburetor; said modified carburetor equipped with a means for restricting flow of atmospheric gases into said carburetor; said modified carburetor equipped with a means for restricting fuel flow within same said modified carburetor; and a means for the introduction of additional oxygen during engine acceleration.

Claim 10

In combination with a standard internal combustion engine a means for reducing the expulsion of air pollutants while maintaining fuel economy and safe usage of a supplemental oxygen supply which comprises a pressurized oxygen supply; a means for reducing the oxygen pressure; means for conducting such oxygen to a safety valve; means for opening and closing said safety valve independently in response to both the engine ignition system and a parameter responsive to both engine activation and shut down; means for further conducting said oxygen to a regulator means; said regulator means which supplies a variable volume of oxygen dependent on the needs of the engine; means of conducting said oxygen to the throat of a modified carburetor; said modified carburetor equipped with a means for restricting flow of atmospheric gases into said carburetor; said modified carburetor equipped with a means for restricting fuel flow within same said modified carburetor; and a means for the introduction of additional oxygen during engine acceleration.

Claim 11

The invention of claim 8 wherein said means for the introduction of additional oxygen comprises; a means for conducting oxygen in series with the primary oxygen conducting means between the safety valve means and the modified carburetor; and said means for conducting oxygen in series is fitted with a flow control valve which is opened or closed by a regulatory means; and said regulatory means is activated or deactivated in response to engine acceleration or deceleration.

Claim 12

The invention of claim 8 wherein said means for the introduction of additional oxygen consists of; a bellows which is attached to the conducting means between the control means and the modified carburetor and is compressed in conjunction to engine acceleration forcing additional oxygen into the conducting means attached to the modified carburetor.

Claim 13

The invention of claim 8 wherein said means for the introduction of additional oxygen consists of; a reservoir connected in series with the means for conducting oxygen between the control valve means and the modified carburetor; said reservoir is fitted with a valve at both its inlet and outlet; said valve of reservoir outlet is opened in response to engine acceleration and closed in response to normalization of engine speed; said valve at reservoir inlet is opened in response to closing of reservoir outlet valve; said valve at reservoir inlet is closed in response to engine deceleration.
