Abstract: A system for increasing the power and efficiency of engines by increasing the oxygen content in the intake manifold supply using a zeolite filtration system. This system converts the air to a higher oxygen content as it flows to the intake manifold in an engine. The practical idea of this is to increase the power of the engine without increasing displacement, while almost completely diminish NOx emissions as well as reducing fuel consumption. In this invention there are three main components: the zeolite filtration oxygen enrichment system, a system for desorbing nitrogen within the filter when the engine is off or idle, and a wastegate for controlling oxygen enrichment or no oxygen enrichment.

Abstract: During starting of an engine that has a circulation path through which argon, used as working gas, is circulated back to a combustion chamber and that uses hydrogen as fuel during operation, oxygen is supplied in such a manner that the oxygen supply ratio is higher than that used during normal operation. Thus, the entirety of hydrogen supplied into the combustion chamber reacts with oxygen and is burned. When the engine is being started, because gas is not turbulent enough, hydrogen and oxygen are likely to be mixed poorly. Therefore, when oxygen is supplied in such a manner that the ratio of oxygen supply amount to the hydrogen supply amount is higher than the theoretical ratio, even if oxygen and hydrogen are not mixed so well, the chance that hydrogen contacts oxygen is increased. As a result, combustion takes place in a more appropriate manner, which improves the engine startability.

Abstract: An internal-combustion engine receives no air from outside atmosphere and it discharges no gas into outside atmosphere. The engine receives fuel, oxygen and recycled combustion gas and its exhaust consists mostly of carbon dioxide and water vapor. Most of the gas exhausted from the engine is recycled back into the engine intake, and the remaining gas is cooled and condensed into liquid carbon dioxide and water. Discharge of greenhouse gas into environment and emission of other harmful air pollutants are eliminated.

Abstract: An internal-combustion engine receives no air from outside atmosphere. Instead, combustion gas expelled from the engine is cooled and recycled back into the engine. That gas contains no nitrogen and consists mostly of carbon dioxide and water vapor. Oxygen and fuel are added to the recycled gas, and the resulting mixture is used to perform an internal-combustion cycle. A small amount of the expelled combustion gas is discharged into outside environment, and the rest is recycled. Since no nitrogen is present, no nitrogen oxides are produced. The amount of other harmful exhaust emissions, including particulate matter, is greatly reduced too, since most of them are recycled back into the engine. The engine is inherently supercharged with combustion-gas pressure and, since the combustion gas is heavier than air, the engine can be substantially smaller than a conventional engine of equal power. Direct injection of oxygen leads to further reduction in engine size. A smaller engine has much better fuel economy.

Abstract: An ignition system for use with an engine is disclosed. The ignition system may have an igniter connected to selectively ignite a fuel mixture within the engine, an injector located to inject a non-combustible gas into the engine, and a controller in communication with the igniter and the injector. The controller may be configured to energize the igniter during a first mode of engine operation to ignite the fuel mixture, and cease energizing the igniter during a second mode of engine operation. The controller may also be configured to actuate the injector during the second mode of engine operation to promote auto-ignition of the fuel mixture.

Abstract: Oxygen can make any fuel more flammable, more powerful and burn more efficiently. When oxygen is mixed with the normal air that enters the air intake of an internal combustion engine, the engine runs faster and creates more power using the same amount of fuel. Because more fuel is burned, there are less exhaust fumes and the engine runs cleaner. Due to the high cost of oxygen, the Internal Combustion Oxygen Injection Process would not be practical or feasible cost wise. The answer to the Internal Combustion Oxygen Injection Process is using an oxygen concentrator which concentrates oxygen from the air around us. There is a control value on the oxygen concentrator that regulates the liters per minute of oxygen that it produces. This makes it possible to regulate the amount of oxygen needed for every type of internal combustion engine.

The acceleration fuel pump has a plunger which inserts sealably into a cylindrical cavity carried by the body of the carburetor. During acceleration of the engine, the plunger inserts further into the cavity against the resilient force of a spring and toward a resilient check valve member causing the member to deform into a fuel feed state. A fuel passage which extends between the bottom of a fuel chamber of the carburetor and the fuel-and-air mixing passage of the carburetor is intersected by the cavity and the resilient check valve member.

SDO may also be generated through reactions of a chemical fuel additive or a laser-excited chemical additive. A system for improving the performance of an internal combustion engine according to the invention includes a source or energy operative to generate singlet delta oxygen (SDO) from molecular oxygen, and apparatus for mixing the SDO with fuel prior to, or during, combustion. In the preferred embodiment, the SDO is delivered with air through an air-intake port, and a laser is used in a multi-pass absorption cell.

Abstract: An internal combustion engine having a combustion heater is capable of enhancing an engine starting characteristic by improving warm-up of the engine and ensuring a sufficient oxygen content in intake air of the engine. An ECU executes, at the engine starting time, an augmentation control of augmenting the oxygen content in the engine intake air by an air blow fan. Under this augmentation control, the engine intake air is supplemented with the oxygen, and, with this supplement, the engine intake air becomes the intake air with oxygen content that is effective enough for starting the engine.

Abstract: An emission control system for reducing total particulates and NO.sub.X emissions from the exhaust of a diesel engine includes an air supply system that supplies oxygen enriched air to an air intake of the engine. The air supply system may include a selectively permeable air separating membrane device for producing the oxygen enriched air. In order to effectively utilize the increase in the concentration level of oxygen in the intake air, the amount of fuel being supplied to the diesel engine also is increased at a minimum in proportion to the increased concentration level of oxygen in the intake air. The increase in the amount of such fuel being supplied to the diesel engine can be adjusted by an electronic fuel injection system used on such diesel engines. In addition, the electronic fuel injection system is used to retard the injection timing of the engine.
