Patent number: 10415600Abstract: A turbocharger and a method are disclosed. The turbocharger includes a casing having an inlet end and an outlet end. A flow passage within the casing may have a substantially continuous inner surface and may be configured to pass inlet air from the inlet end to the outlet end. A compressor wheel may be located in the casing and may have at least one main blade and may be configured to rotate within the casing to compress the inlet air. A flow disrupting feature on the casing may be configured to disrupt the continuity of the inner surface and may be located at a leading edge of the at least one main blade. The flow disrupting feature may be closed to upstream communication with the flow passage except via the flow passage.Type: GrantFiled: August 12, 2016Date of Patent: September 17, 2019Assignee: Ford Global Technologies, LLCInventors: Ahsanul Karim, Brian W. Lizotte, Keith D. Miazgowicz, Abdelkrim Zouani

Patent number: 10337529Abstract: Methods and systems are provided for a compressor of a turbocharger of an engine. In one example, a compressor may include a flow passage and a resonance chamber surrounding the flow passage, with the flow passage fluidly coupled with the resonance chamber by a recirculation passage, a bleed passage, and a plurality of apertures positioned between the recirculation passage and the bleed passage. Flowing fluid from the resonance chamber, through the apertures, and into the flow passage may reduce a noise level of the compressor.Type: GrantFiled: November 4, 2016Date of Patent: July 2, 2019Assignee: Ford Global Technologies, LLCInventors: Ahsanul Karim, Chris David Tiernan, Keith D. Miazgowicz, Timothy J. Knott, Anthony Morelli

Patent number: 10138803Abstract: Methods and systems are provided for a wastegate of a turbocharger including a valve plate, valve actuation mechanism, and a bifurcated wastegate passage. In one example design, the wastegate may include a valve plate having an interior with a multiplane curved surface and a first mating feature centered along the curved surface, the curved surface forming a raised edge and a side opening on opposite sides of the valve plate; and a passage bifurcated by a central wall, an end of the central wall including a second mating feature adapted to have face-sharing contact with the first mating feature. The first mating feature may be either a rib or recessed slot formed on the valve plate, and the second mating feature may be one end of the central wall.Type: GrantFiled: June 15, 2017Date of Patent: November 27, 2018Assignee: Ford Global Technologies, LLCInventors: Keith D.

Patent number: 10125671Abstract: Methods and systems are provided for a wastegate of a turbocharger including a valve plate, valve actuation mechanism, and a wastegate passage. In one example design, the wastegate may include a valve plate having flow formations such as a multiplane curved surface on an interior of the valve plate and a side opening; a passage including a constricted section positioned upstream of the valve plate, the valve plate positioned at an end of the passage. In this way, the flow formations on the wastegate valve may act in conjunction with the constricted section in the passage to guide exhaust flow to an exhaust catalyst.Type: GrantFiled: November 9, 2016Date of Patent: November 13, 2018Assignee: Ford Global Technologies, LLCInventors: Gilbran D. Alvarez, Keith D. Miazgowicz
