Patent number: 10113611Abstract: A torsional vibration damper mounted at a crankshaft of an engine is provided. The torsional vibration damper comprises a hub having a first mounting surface and a second mounting surface opposite to the first mounting surface, an inertia ring and an elastomer element disposed between the hub and the inertia ring. The hub includes a first mounting hole configured to receive the crankshaft, and at least one slot spaced apart from the first mounting hole. The slot is configured such that a center-of-gravity of the torsional vibration damper is offset from a central axis of the crankshaft.Type: GrantFiled: August 30, 2017Date of Patent: October 30, 2018Assignee: Ford Global Technologies, LLCInventors: Bruce Li, Bin Yin, Dallis Sun, Baocheng Sun, Jagadish Sorab

Patent number: 7077776Abstract: A heat exchanger integrated into the transmission oil pan transfers heat from post-catalyst exhaust gases to the transmission oil. Inlet and outlet ducts route exhaust gas between the heat exchanger and an exhaust pipe located downstream of the catalyst. The exhaust pipe accommodates a control valve that diverts exhaust gas flow to the heat exchanger during the warm-up phase, or to the tailpipe during steady state operation. A control function is provided to monitor transmission oil temperature and engine operating conditions and to control actuation of the valve. The main input parameter to the control function is the transmission oil temperature.Type: GrantFiled: March 15, 2004Date of Patent: July 18, 2006Assignee: Ford Global Technologies, LLCInventors: Jagadish Sorab, Tom Tibbles, Michael Schroder, John Glidewell

Patent number: 6976456Abstract: An adjustable connecting rod system includes a reliable, rapidly responsive mechanism for varying effective connecting rod length to vary the compression ratio of the engine. The mechanism may employ the momentum of connecting rod components during operation of the engine to provide actuation force to vary connecting rod length. Connecting rod length is preferably controlled by manipulation of fluid-actuated locking members. In a preferred embodiment, hydraulic pressure is applied through the use of engine oil or other hydraulic fluids. The connecting rod preferably employs one or more movable compression members such as roller members or other mechanical components that may be shifted from one position to another with relatively little friction in order to vary the effective length of the connecting rod. The movable compression members may engage surfaces of both the crankpin bearing retainer and the connecting rod body, loaded in compression to transmit forces therebetween.Type: GrantFiled: June 26, 2003Date of Patent: December 20, 2005Assignee: Ford Global Technologies, LLCInventors: Yitzhak Isaac Henig, Jeffrey Eliot Chottiner, Jagadish Sorab, Pravin Sashidharan, Satheesh Makkapati

Publication number: 20050202921Abstract: A super-finished rear axle gear set for a vehicle is provided for improving rear axle efficiency. The rear axle gear set includes a ring gear and a pinion gear. The super-finish is applied to at least the ring gear teeth and pinion gear teeth. The super-finish causes the teeth to be smoother, thus decreasing the coefficient of friction between the teeth when the pinion gear teeth drive the ring gear.Type: ApplicationFiled: March 9, 2004Publication date: September 15, 2005Applicant: FORD GLOBAL TECHNOLOGIES, LLCInventors: Arup Gangopadhyay, Jagadish Sorab, Michael Schroder, Sam Asaro
