20110113758 | EXHAUST LINE WITH REAGENT INJECTOR - An exhaust line includes: a duct ( | 05-19-2011 |
20120216513 | EXHAUST LINE WITH INJECTION SYSTEM - An exhaust line has upstream and downstream blocks for processing exhaust gases. An injection section is arranged between an upstream face defined by the upstream block and a downstream face defined by the downstream block and includes a circulation channel for the exhaust gas flow extending from the upstream face to the downstream face. The channel includes a central line having a determined length between the upstream and downstream faces. The injection section includes a reagent injector capable of injecting a reagent into the injection section. The injection section has a first cup inside the circulation channel in the flow path such that the average path of exhaust gas jets is higher by at least 20% in relation to the predetermined length. A second cup is arranged inside the circulation channel between the upstream face and the first cup. The reagent is done between the first cup and the second cup. | 08-30-2012 |
20130118722 | Spiral Exchanger and Method for Manufacturing Such an Exchanger - A spiral exchanger has a winding axis and comprises an outer sheet and an inner sheet secured to one another in a fastening plane before winding and delimiting a space for a fluid between them. The outer sheet and the inner sheet are wound on themselves and each comprises a plurality of flexible areas and a plurality of rigid areas, the flexible areas being more flexible than the rigid areas during folding. The flexible areas and the rigid areas are extended along the winding axis, and at least one flexible area of the outer sheet and at least one flexible area of the inner sheet that delimit the space between them form a pair of flexible areas that are aligned in a same radial direction. | 05-16-2013 |
20130213606 | HEAT RECUPERATION DEVICE FOR AN EXHAUST LINE - The heat recuperation device for an exhaust line comprises

20130327021 | DEVICE FOR GENERATING AMMONIA - An ammonia generating device is delimited by an outer casing that includes a main reservoir and a secondary reservoir. The main reservoir is capable of reloading with ammonia the body in the secondary reservoir. A heater is capable of heating the bodies in each reservoir. A connector connects the main reservoir to the secondary reservoir. The heater comprises first and second heating devices respectively installed inside the main reservoir and the secondary reservoir and operating independently. The main reservoir is thermally decoupled from the secondary reservoir to generate a temperature gradient between both reservoirs. | 12-12-2013 |
20130327022 | DEVICE FOR GENERATING AMMONIA - An ammonia generating device for treating exhaust gases of internal combustion engines, notably of automobile vehicles, includes a reservoir having a body capable of releasing ammonia by desorption and a heating device positioned inside the reservoir to heat the body in the reservoir. The heating device comprises a heat generating element that has an elongated form. The heating device further includes at least one heat transfer feature laid out along an axial direction of the heat generating element and extending in a direction radial to the heat generating element. | 12-12-2013 |
20140044603 | DEVICE FOR GENERATING AMMONIA - An exhaust line of a motor vehicle includes an upstream monolith and a downstream monolith for treating exhaust gases passing along the exhaust line. The upstream and downstream monoliths are positioned in series. | 02-13-2014 |
20150322841 | Exhaust Line Comprising a Heat Exchanger, Corresponding Manufacturing Process and ... - An exhaust line includes a spiral heat exchanger having a first passage for a first fluid and a second passage for a second fluid. The second passage is arranged in a manner such that the second fluid circulates from an inlet firstly in at least one first circumferential segment disposed in a proximity of a first axial end and then into a plurality of second circumferential segments shifted towards a second axial end relative to the first circumferential segment. The second fluid advances axially in a counter current flow against the first fluid towards the first axial end while passing from one second circumferential segment to the next. | 11-12-2015 |
20150323260 | Spiral Heat Exchanger and Corresponding Manufacturing Method - The heat exchanger comprises a lower metal sheet, —an upper metal sheet, and a fin sheet delimiting the fins. The lower metal sheet, the upper metal sheet and the fin sheet form a three-layer structure wound in a spiral, whereby the lower metal sheet and the upper metal sheet delimit a first passage for the circulation of a first fluid. The heat exchanger has a set of spacers arranged in the first passage, whereby these spacers are rods separate from the lower and upper metal sheets. | 11-12-2015 |
