Patent number: 8955641Abstract: An exhaust system includes first and second exhaust components with an inter-pipe that fluidly connects an outlet of the first exhaust component to an inlet of the second exhaust component. A passive valve is mounted within the inter-pipe. The second exhaust component defines an internal cavity that is at least partially packed with a high frequency absorption material and cooperates with the passive valve to effectively attenuate low and high frequency noise.Type: GrantFiled: March 28, 2013Date of Patent: February 17, 2015Assignee: Faurecia Emissions Control Technologies, USA, LLCInventors: Kwin Abram, Ivan Arbuckle, Kamilla Iskenderova, James Egan, Dennis Shaw

Patent number: 8453672Abstract: A passive valve assembly for an exhaust system is mounted within an exhaust tube. The exhaust tube has a bore that defines an exhaust flow path having a cross-sectional area. One end of the exhaust tube is to be connected to a first exhaust component and a second end of the exhaust tube is to be connected to a second exhaust component such that the exhaust tube forms a sole exhaust path between the first and the second exhaust components. The passive valve assembly includes a vane that is mounted within the bore, and which is moveable between an open position and a closed position. A resilient member biases the vane toward the closed position. When the vane is in the closed position, the vane covers 80% to 97% of the cross-sectional area.Type: GrantFiled: December 4, 2007Date of Patent: June 4, 2013Assignee: Emcon Technologies LLCInventors: Kwin Abram, Joseph Callahan, Robin Willats, Ivan Arbuckle

Patent number: 8365522Abstract: A dual exhaust system includes a first exhaust component defining a first exhaust path and a second exhaust component defining a second exhaust path that is different from the first exhaust path. A first valve is associated with the first exhaust path and a second valve is associated with the second exhaust path. The first valve and second valve operate independently of each other to vary exhaust flow and provide sufficient noise control for varying applications.Type: GrantFiled: August 17, 2009Date of Patent: February 5, 2013Assignee: Emcon Technologies LLCInventors: Kwin Abram, Ivan Arbuckle, Joseph E.

Publication number: 20110308560Abstract: A vehicle exhaust system includes an exhaust pipe that provides heated exhaust gases to a thermoelectric unit as an input. A temperature control mechanism ensures that exhaust gas is directed into the thermoelectric unit only if the exhaust gas is within a specified temperature range. The thermoelectric unit transforms the exhaust gas heat into electrical power.Type: ApplicationFiled: February 12, 2010Publication date: December 22, 2011Inventors: Ivan Arbuckle, Kwin Abram, Joseph E.

Patent number: 7575096Abstract: A muffler assembly includes first and second muffler components that are each formed as a single piece. The first muffler component includes a first outlet pipe portion, a first bypass pipe mount portion, and a first resonator shell portion. The second muffler component includes a second output pipe portion, a second bypass pipe mount portion, and a second resonator shell portion. The first and second muffler components are positioned in an overlapping relationship such that respective portions are aligned with each other to form an outlet pipe, a bypass pipe mount, and a resonator shell. A noise attenuation valve assembly is also installed within the first and second muffler components. The bypass pipe mount is positioned at a non-perpendicular orientation relative to the outlet pipe such that a bypass pipe having a straight end mount can be received within the bypass pipe mount to bypass the noise attenuation valve assembly.Type: GrantFiled: September 21, 2005Date of Patent: August 18, 2009Assignee: EMCON Technologies LLCInventors: Ivan Arbuckle, Robin Willats, Joseph E.

Publication number: 20090084998Abstract: A control mechanism for a noise attenuation valve in a vehicle exhaust system is configured to significantly reduce operational noises. The noise attenuation valve includes a flapper valve (18) that is supported on a shaft (16) for rotation within an inlet tube (14). The shaft is coupled to an actuator (27) with a linkage assembly (30). The linkage assembly (30) includes a lever (42) that contacts noise attenuation pads (48) at maximum travel limits defined by a backing plate (46) to reduce operational noise. In one example configuration, the actuator provides a bottomless solenoid configuration and utilizes a pulse width modulation control module to further reduce operational noises.Type: ApplicationFiled: September 8, 2005Publication date: April 2, 2009Inventors: Joseph Callahan, Ivan Arbuckle, Kwin Abram
