Filed:

Apr 9, 2004

Appl. No.:

10/822448

Inventors:

Michael Moses Schechter - Farmington Hills MI, US

International Classification:

B60K 6/12

US Classification:

180165

Abstract:

A vehicle engine has a system of valves that permits various engine cylinders to operate in different modes of operation. During braking, some of the engine cylinders receive atmospheric air, compress it, and transfer it to an intermediate air-container. Other cylinders receive compressed air from the intermediate air-container, further compress it, and transfer it to a high-pressure air-reservoir for storage. During acceleration, some of the engine cylinders receive compressed air from the high-pressure air-reservoir, expand it to a lower level of pressure, and transfer it to the intermediate air-container. Other cylinders receive air from the intermediate air-container, further expand it, and use it for combustion in an internal-combustion cycle. During short stops, the engine is shut down, for the duration of the stop, and, then, it is restarted with compressed air. During cruise, the engine operates as a conventional internal-combustion engine.

International Classification:

F01L 1/34

US Classification:

123 9015, 123 9016, 123 9012, 123 68, 60698, 180165

Abstract:

An air-hybrid engine operates in two operational modes. It employs uniquely designed camshafts with cam lobe activators, and camshaft phase shifters to operate and control the engine valves. It uses a different cam lobe for operating an engine valve during each of the two operational modes, and it uses camshaft phase shifters to vary the valve event timing and duration. The system exploits non-linearity that exists in relationship between the piston motion and the camshaft rotation. Varying the phase relationship between the camshaft and the engine crankshaft in a pre-determined specific way varies the duration of the engine valve opening in the required way, thus varying the volumes of air received into and discharged from the engine.

International Classification:

F02B 19/00

US Classification:

180165, 123255, 123258

Abstract:

High vehicle fuel efficiency is achieved by reducing fuel consumption during driving both in the city and on the highway. During driving in the city, the system accumulates the energy derived from vehicle motion during braking, and uses it to assist in vehicle propulsion at a later time. The energy can be stored either in a compressed-air reservoir or in an electric battery. During cruising on the highway, the engine operates in a two-stage gas-expansion cycle. The engine has primary and secondary cylinders. Only primary cylinders operate in internal-combustion mode. After expansion in primary cylinders, combustion gas is subjected to a second stage of expansion in secondary cylinders. This substantially improves the engine efficiency. Whenever heavy engine load is needed, all cylinders operate in internal-combustion mode.

Inventors:

Michael Moses Schechter - Farmington Hills MI, US

International Classification:

F02M 25/07

US Classification:

123567, 12356812

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.

US Classification:

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. Cooling that gas condenses its water vapor, and liquid water is separated from the gas. That water is used for injection into the recycled gas at a later time. A small amount of the expelled combustion gas is discharged into outside environment, and the rest is recycled. Water too is recycled back into the engine, and whatever is lost to outside environment is replaced by reclaiming water produced in combustion. No additional supply of water is needed. Since no nitrogen is present, no nitrogen oxides are produced.

Abstract:

A gas-turbine 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 process. 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 controllable combustion-gas pressure and, in some cases, can operate without a compressor. Since the combustion gas is heavier than air, the engine can be substantially smaller than a conventional engine of equal power. Complete elimination of nitrogen oxide emissions and a significant reduction in particulate matter can substantially increase appeal of gas-turbine engines based on the above concept.

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.
