Patent number: 10480616Abstract: An engine assembly has a damper rotationally coupled to a crankshaft. The damper has first and second spokes connecting a hub to an inertial weight, with the inertial weight circumferentially surrounding and spaced apart from the hub. Each of the spokes has an airfoil section. The first spoke is oriented with a positive angle of attack and the second spoke is oriented with one of a negative angle of attack and a zero angle of attack. A crankshaft damper is provided by a member having first and second spokes extending radially outwardly from a huh to an outer rim supporting an inertial weight. A chord associated with the first spoke is oriented at a first angle of attack relative to a rotational plane of the member. A chord associated with the second spoke is oriented at a second angle of attack relative to the rotational plane.Type: GrantFiled: October 25, 2017Date of Patent: November 19, 2019Assignee: Ford Global Technologies, LLCInventors: Ahsanul Karim, Abdelkrim Zouani, Michael Stanley

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
