20110023796 | Adaptive EGR Cooling System - A first loop contains engine coolant passageways ( | 02-03-2011 |
20110023840 | Exhaust Gas Cooler - A method of cooling exhaust gas (F) from an engine in an EGR cooler ( | 02-03-2011 |
20110030371 | SYSTEM USING SUPPLEMENTAL COMPRESSOR FOR EGR - A system for driving an EGR stream for an engine includes an exhaust gas turbine, a main compressor and a supplemental EGR compressor. The turbine drives the main compressor to pressurize intake air and drives the supplemental EGR compressor to pressurize an EGR exhaust gas stream to be introduced into the intake air system. A supplemental EGR compressor takes suction of exhaust gas downstream from the turbine. A three-way valve proportions exhaust gas between the engine exhaust gas discharge conduit and the suction of the supplemental EGR compressor. The turbine drives a shaft and the main compressor and the supplemental EGR compressor are driven by having corresponding compressor wheels fixed onto the common shaft. | 02-10-2011 |
20110083648 | FLEX Dual Stage EGR Cooling - A circuit for cooling exhaust gas being recirculated through an EGR system ( | 04-14-2011 |
20110108013 | EXHAUST GAS RECIRCULATION VALVE WITH BYPASS CAPABILITY AND METHOD - Unique to this invention is the design of an Exhaust Gas Recirculation (EGR) valve with bypass capabilities. EGR valves combined with a bypass valve are expensive to design and manufacture due to their complexity and unique differences. Furthermore, the reliability of multiple components is much lower than that of the single component. During various engine operating conditions it is necessary to divert the flow of exhaust gas around the EGR cooler through the intake manifold or through the EGR cooler to lower the temperature of the exhaust gas to reduce noxious emissions. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. | 05-12-2011 |
20140208743 | TURBOCHARGER OPERATION TO INCREASE BRAKE EFFECTIVENESS - In response to activation of a compression release brake when a motor vehicle having a turbocharged internal combustion engine is operating at some elevation above sea level and a turbocharger compressor is operating in a region of an operating map which is creating boost air in an engine intake manifold which would cause the compression release brake to decelerate the vehicle more slowly at that elevation than it would at sea level for the same operating conditions of the vehicle and engine other than altitude, the compression release brake decelerates the vehicle less slowly by causing an exhaust gas recirculation system to reduce at least one of a) mass of exhaust diverted to an intake system of the engine and b) cooling of the diverted exhaust. | 07-31-2014 |
20140216398 | TURBOCHARGER OPERATION TO INCREASE BRAKE EFFECTIVENESS - In response to activation of a compression release brake when a motor vehicle having a turbocharged internal combustion engine is operating at some elevation above sea level and a turbocharger compressor is operating in a region of an operating map which is creating boost air in an engine intake manifold which would cause the compression release brake to decelerate the vehicle more slowly at that elevation than it would at sea level for the same operating conditions of the vehicle and engine other than altitude, the compression release brake decelerates the vehicle less slowly by operating a valve mechanism to reduce flow through a charge air cooler and increase flow through a charge air cooler by-pass. | 08-07-2014 |
20140352938 | EGR COOLER HEADER DESIGN - A heat exchanger having a modified header design for absorbing high thermal loads, is described. The heat exchanger includes a housing having an interior space, a core within the interior space of the housing, the core comprising a plurality of flow passages, and a header positioned at an end of the housing and in communication with the core, wherein the header includes a thermal absorbing formation. The thermal absorbing formation may take the form of a continuous raised rib around an inner circumference of the header. The raised rib absorbs excess heat and reduces thermal strain on the heat exchanger. | 12-04-2014 |
