Abstract: An energy production and pressurized exhaust gas storage system including two combustion chambers aligned in opposition to each other, each of the two combustion chambers having a reciprocating power piston. A compression chamber is situated between the two combustion chambers and it includes a reciprocating compression piston. A shaft connects all of the pistons together. A solvent tank is connected to the two combustion chambers to receive the exhaust gas carbon dioxide. The solvent is preferably water maintained at about 32 degrees Fahrenheit and with a pressure above the water surface of about 100 pounds per square inch. Upon combustion, a pressurized carbon dioxide storage chamber receives compressed carbon dioxide from the compression chamber. Check valves are used to enable inflow of carbon dioxide to the compression chamber from the solvent tank and outflow of pressurized carbon dioxide in the compression chamber to storage.

Abstract: An engine system comprises a fuel processor that is supplied with air and a fuel stream to produce a hydrogen-containing gas stream. The fuel processor comprises a housing, and at least a portion of the housing is located within an exhaust stream conduit from the engine. During operation of the engine, heat transfer between the fuel processor and the engine exhaust stream occurs. An exhaust after-treatment assembly is located downstream of the fuel processor and is connected to selectively receive hydrogen-containing gas stream from the fuel processor.

Abstract: In an internal combustion engine having several combustion chambers formed in in-line cylinders wherein an air/fuel mixture can be combusted and which include a common cylinder head, with discharge passages formed within the cylinder head and extending to a common confluence zone in communication with a discharge manifold, the common confluence zone is delimited on a first side (A) by at least one cylinder head wall and a separate shell element on a second side mounted to the outside of the cylinder head, the shell element being curved funnel-like for conducting the exhaust gas away from the engine.

Abstract: A steam generation system comprises: an oxygenated water treatment (OWT) sub-system configured to generate water having oxidizing chemistry; a steam generation sub-system configured to convert the water having oxidizing chemistry into steam having oxidizing chemistry; an attemperator or other injection device or devices configured to add an oxygen scavenger to the steam having oxidizing chemistry to generate steam having less oxidizing or reducing chemistry; and a condenser configured to condense the steam having less oxidizing or reducing chemistry into condensed water.

Abstract: An environment-conservative fuel economizer includes a hollow tubular member and at least one ring member. The tubular member has an internal surface forming a reduced neck section. The ring member is mounted to an end of the tubular member. The ring member forms a plurality of cut-off slits, which defines a plurality of deformable leaves. The neck section of the tubular member forms a flow-accelerating passage, which increases speed of air flow passing therethrough to induce secondary combustion. The leaves are allowed to selectively expand/contract to effect complete combustion and reduce pollution. The fuel economizer is installed between an automobile air filter and engine air-intake tube to use the suction force induce by air intake of cylinder to draw in air so that the mixture density of air and atomized fuel is intensified to effect complete combustion of fuel and enhance instantaneously engine torque and reduce fuel consumption.

Abstract: The exhaust gas purification device has a first chamber having an exhaust pipe inlet, an ambient air inlet, and an exhaust gas outlet. A Venturi is arranged within the chamber, having an inlet end communicating with an ambient air inlet, a throat, and an outlet end communicating with an exhaust gas outlet. The Venturi has an exhaust gas inlet between its inlet end and its outlet end, receiving exhaust gas from within the chamber, directed generally towards the outlet end of the Venturi, so that ambient air and exhaust air are mixed in passing through the Venturi to its exhaust gas outlet. A perforated pipe within the first chamber receives the exhaust gas, and the exhaust gas escapes there from via the perforations, into the chamber and thence to the Venturi. A second chamber, having a catalytic substrate assembly mounted therein, receives the mixed ambient air and exhaust air from the exhaust gas outlet of the Venturi, and has an exhaust pipe outlet.

Abstract: The invention concerns an exhaust gas cooler employed with a tailpipe of a vehicle exhaust system and a method of cooling exhaust gasses before being emitted from the exhaust system into the atmosphere. The exhaust gas cooler may include a cooler housing having a substantially cylindrical shape with an open forward edge, an open rearward edge, and an internal diameter that is larger than the external diameter of the tailpipe, and a cooler support attached to and supporting the cooler housing such that the rearward edge of the tailpipe is located within the cooler housing between the forward and rearward edges of the cooler housing.

Abstract: Rhodium utilization in LNT/SCR-based exhaust aftertreatment systems for medium and heavy duty trucks is reduced by operating inline fuel reformers in a certain manner. The fuel processors are operated at steam reforming temperatures to produce a reformate-containing exhaust having a hydrogen to CO ratio of at least about 3:2 or at least about 3% hydrogen, This generally involves operating the fuel reformers at temperatures from about 500 to about 625° C. and with an overall fuel to air ratio from about 1.10 to about 1.40. In this manner, regeneration can be efficiently carried out while limiting the catalyst loading of the fuel processors to no more than about 1.0 grams rhodium per liter maximum displacement of the diesel engine and the catalyst loading of the LNTs to no more than about 0.50 grams rhodium per liter maximum displacement of the diesel engine.

Abstract: Inlet air (15) humidified in an air bubbling (or other) humidifier (35) that receives water from a tank (36) is sent to a hydrogen generator (27) along with vaporized (23) diesel fuel (22) to produce hydrogen and carbon monoxide (28) for either (a) mixing with the mainstream of exhaust (18) fed to a catalytic converter (30) or (b) regenerating a pair of NOx adsorption traps (38, 39), thereby reducing oxides of nitrogen (NOx), to provide system exhaust (32) which may have less than 0.40 grams/bhp/hr of NOx and 0.28 grams/bhp/hr of non-methane hydrocarbons. In other embodiments, unhumidified air mixed with fuel feeds a homogeneous non-catalytic partial oxidizer (27) to provide the required hydrogen and carbon monoxide.

Abstract: An improved water cooled exhaust valve structure is disclosed for a rotary valve engine. The exhaust gases from an engine combustion chamber enter a side port in a rotary exhaust valve and flow axially through the valve to an exhaust outlet. Cooling water is sprayed axially into the exhaust valve and is directed in the gas flow direction from a location upstream of the side port. A novel deflector prevents the cooling water from entering the side port.
