Patent number: 7654078Abstract: A particle collector includes a housing within an internal chamber having inlet and outlet ports. The housing can comprise two joined-together housing members. A collector element is disposed in the internal chamber and includes a particulate passage extending axially therethrough. A gas passageway is disposed within the chamber between a housing inside diameter and a collector element outside diameter, and is sized to produce a minimal pressure drop through the particle collector. The collector element is connected to the housing. A collection port is connected with the collector element and extends from the particulate passage to a location outside of the internal chamber for removing collected particulate matter from within the housing when the particle collector is placed into operation within an exhaust gas flow stream.Type: GrantFiled: May 8, 2006Date of Patent: February 2, 2010Assignee: Honeywell International, Inc.Inventors: Damien Marsal, Phillipe Renaud, Jerome Mlika

Patent number: 7568340Abstract: The present invention provides an exhaust gas recirculation mixer for use with a long route (i.e., low pressure) EGR system adapted for use in a turbocharged internal combustion engine. The mixer comprises an outer wall and an inner wall defining a cavity therebetween, a chamber defined within the inner wall, an exhaust gas inlet on the outer wall, and apertures of varying dimensions disposed within the inner wall so that exhaust gas enters the mixer in a controlled flow through the exhaust gas inlet, through the cavity, and through the apertures into the chamber for mixture with ambient air.Type: GrantFiled: May 24, 2006Date of Patent: August 4, 2009Assignee: Honeywell International, Inc.Inventors: Damien Marsal, Junfei Yin, Nicolas Deschatrettes, Joan-Pierrs Toniolo, Ocean Han
