20090301070 | VAPORIZATION DEVICE FOR A MOTOR VEHICLE EXHAUST SYSTEM, EXHAUST SYSTEM FOR A MOTOR VEHICLE AND METHOD FOR PRODUCING A VAPORIZATION DEVICE - A vaporization device for a motor vehicle exhaust system vaporizes an oxidizable liquid and introduces a vapor produced from the oxidizable liquid into an exhaust gas flow of the motor vehicle exhaust system. The vaporization device includes a heating element that is arranged in a housing, and which has the form of a glowing filament. The housing has an inlet for the liquid, at least one vaporization chamber, and an outlet for the vapor. The glowing filament is embedded in a glow tube surrounding the glowing filament. The glowing filament and the glow tube constitute a prefabricated unit which is fastened on a side of the housing by the glow tube being mounted directly to the housing. Furthermore, an exhaust system having a vaporization device, and a method of producing a vaporization device are described. | 12-10-2009 |

20100205946 | ENGINE EXHAUST HEAT RECOVERY DEVICE, AND ENERGY SUPPLY APPARATUS USING THE SAME - [Problems] Provided is a configuration in which a member is not interposed between exhaust gas and a partition wall of an engine coolant passage, and the exhaust gas is caused to directly collide with the partition wall of the engine coolant passage, thus raising the gas flow velocity in a heat exchange part, which enables further improving the exhaust heat recovery rate. | 08-19-2010 |
20100229540 | Combination Liquid-Cooled Exhaust Manifold Assembly And Catalytic Converter Assembly For A Marine Engine - An exhaust system for a marine engine comprising liquid cooled manifold and catalytic converter assemblies. Each assembly uses a separate cooling system to cool either the exhaust manifold or a shell inside which resides the catalytic converter. The housing or shell containing the catalytic converter uses water to cool an exterior surface of a water jacket to an acceptable temperature conforming to federal regulations. The liquid-cooled manifold assembly may use either water or glycol to cool a jacket surrounding tubes extending from the engine block to the catalytic converter assembly. | 09-16-2010 |
20120144810 | EXHAUST GAS POST PROCESSING SYSTEM - An exhaust gas post processing system may include an exhaust pipe in which an exhaust gas from an engine passes, a catalyst that may be disposed at the exhaust pipe so as to decrease a harmful material of the exhaust gas, and a water jacket that may be formed around an exhaust pipe that may be disposed at an upstream side of the catalyst of the exhaust pipe, wherein a coolant may be selectively supplied into the water jacket such that the water jacket cools down the exhaust gas passing the exhaust pipe and thus the catalyst does not be over heated. | 06-14-2012 |
20140298779 | WALL FLOW TYPE EXHAUST GAS PURIFICATION FILTER - A wall flow type exhaust gas purification filter includes a honeycomb structure body and plugging portions. Four inlet opening cells having a substantially hexagonal shape in cross section surround one outlet opening cell having a substantially square shape in cross section, where one side of an inlet opening cell and one side of the outlet opening cell have a substantially same length and are substantially parallel and adjacent to each other. Distance a between the partition wall defining a first side of the outlet opening cell and the partition wall defining an opposed second side is in a range of exceeding 0.8 mm and less than 2.4 mm, and distance b between the partition wall defining a third side of the inlet opening cell and the partition wall defining an opposed fourth side has a ratio to the distance a in a range exceeding 0.4 and less than 1.1. | 10-09-2014 |
20140298780 | DEVICE FOR EXHAUST-GAS AFTERTREATMENT HAVING A DOSING UNIT FOR AN EXHAUST-GAS AFTERTREATMENT AGENT AND MOTOR VEHICLE HAVING THE DEVICE - A device for the aftertreatment of an exhaust gas of an internal combustion engine flowing through an exhaust line includes at least one dosing unit disposed in an opening of an exhaust pipe of the exhaust line and configured to add an exhaust-gas aftertreatment agent into the exhaust line. The dosing unit is enclosed by a cooling jacket, through which the dosing unit is fastened in the opening of the exhaust pipe. The cooling jacket is at least partially enclosed by a space or chamber delimited at least by the cooling jacket, the exhaust pipe, and a cover plate. The cover plate is connected to the exhaust pipe and spaced apart from the cooling jacket or the dosing unit by a gap. A motor vehicle having the device is also provided. | 10-09-2014 |
20150013314 | CONTROLLING EXHAUST TEMPERATURES - An exhaust manifold cooling jacket has internal passages for the circulation of liquid coolant and encloses an exhaust manifold such that a gap is created between the exhaust manifold and cooling jacket. Flowing coolant through the jacket regulates outer jacket temperature while enabling high intra-manifold exhaust gas temperatures for thorough intra-manifold combustion and improved emissions. A liquid-cooled exhaust system includes a turbocharger disposed between manifold and elbow, with liquid coolant flowing from manifold to elbow through the turbocharger. Another liquid-cooled exhaust manifold contains an internal exhaust combustion catalyst wrapped in an insulating blanket. In some marine applications, seawater or fresh water coolant is discharged into the exhaust gas stream at an attached exhaust elbow. | 01-15-2015 |
20150059322 | LIQUID COOLED REDUCTANT DELIVERY UNIT FOR AUTOMOTIVE SELECTIVE CATALYTIC REDUCTION SYSTEMS - A reductant delivery unit having active cooling which is constructed to have sufficient structural robustness, and to improve corrosion resistance of the assembly, where an attack on the base injector is conceivable with the use of incorrect coolant media. The reductant delivery unit has an upper shield, a lower shield connected to the upper shield, and an inner sleeve. The reductant delivery unit also includes a lower sleeve connected to the inner sleeve and the lower shield. A liquid cooling cavity is formed by the connection between the inner sleeve and the lower shield, the lower sleeve and the lower shield, and the lower sleeve and the inner sleeve. Coolant flows into the liquid cooling cavity to provide a cooling function to an injector partially located within the inner sleeve, and a corrugated portion of the lower sleeve transfers heat away from at least a portion of the injector. | 03-05-2015 |
