Patent number: 10487722Abstract: A turbocharger compressor and method are provided including a first coolant passage in thermal contact with an inlet configured to direct the charge gas toward an impeller; and second, third, and fourth coolant passages respectively in thermal contact with impeller, volute, and diffuser regions. All of the coolant passages are fluidically coupled with a heat exchanger. One or more of the coolant passages are configured such that coolant flows in an upstream direction relative to a general flow direction of charge gas through the compressor.Type: GrantFiled: December 1, 2017Date of Patent: November 26, 2019Assignee: Ford Global Technologies, LLCInventors: Liangjun Hu, David Curtis Ives, Eric Warren Curtis, Jianwen James Yi

Patent number: 10378421Abstract: A vehicle cooling system includes an internal combustion engine, a transmission having a cooler, a coolant pump, a first coolant loop, a second coolant loop, and a flow regulator. The first coolant loop fluidly connects the coolant pump to the engine and returns to the coolant pump. The second coolant loop fluidly connects the coolant pump to the transmission cooler and returns to the coolant pump, bypassing the engine. The flow regulator is configured to selectively restrict coolant flow through the second coolant loop.Type: GrantFiled: September 19, 2014Date of Patent: August 13, 2019Assignee: Ford Global Technologies, LLCInventors: James Thomas Gooden, Michael Joseph Giunta, David Curtis Ives

Patent number: 8671908Abstract: A four-valve per cylinder engine has two intake valves, two exhaust valves and a centrally located fuel injector. Between each adjacent pair of valves is a valve bridge with a point of minimum separation between adjacent valves. In the present disclosure, the glow plug port is defined in the cylinder top at a location outboard of the minimum separation between adjacent and at a depth which is tangent to an edge of a fuel jet emanating the injector. By placing the glow plug farther outboard than found in the prior art, the glow plug contacts the fuel as it comes out of the injector and as it rebounds off a feature of the piston bowl.Type: GrantFiled: July 31, 2009Date of Patent: March 18, 2014Assignee: Ford Global Technologies, LLCInventors: David Curtis Ives, Brien Lloyd Fulton, Eric Matthew Kurtz, Bradley David Opperman, Joshua Putman Styron, Patrick Brian Morgan, Martin Johannes Atzwanger

Patent number: 8596064Abstract: A method for operating a turbocharged engine is disclosed. In one example, an engine operation is adjusted in response to a turbocharger expansion ratio. Degradation of the engine may be reduced under some engine operating conditions by adjusting engine operation in response to the turbocharger expansion ratio.Type: GrantFiled: October 29, 2010Date of Patent: December 3, 2013Assignee: Ford Global Technologies, LLCInventors: Brien Lloyd Fulton, Gopal Krishna Chamarthi, Dean Pennala, David Curtis Ives, David Robert Nader, Paul Martin Niessen, Jason Ronald Smith

Patent number: 8047184Abstract: A system and method for controlling an engine control an EGR cooler bypass valve to divert at least a portion of EGR flow around an EGR cooler when operating under cooler fouling/plugging conditions, such as during idle, off-idle, exhaust system warm up and DPF regeneration or other post injection operation with EGR gas temperature below a corresponding threshold or with EGR low-temperature coolant temperature below a corresponding threshold. The system and method reduce exhaust gases passing through the EGR cooler that contain a high concentration of unburned or partially unburned fuel when the temperature in the EGR system is lower than the fuel condensation temperature.Type: GrantFiled: July 31, 2009Date of Patent: November 1, 2011Assignee: Ford Global Technologies, LLCInventors: Daniel Joseph Styles, Kevin Chen, David Curtis Ives, Frank M Korpics, Norman Hiam Opolsky, Timothy Webb

Patent number: 7971577Abstract: A method to dislodge an adherent residue in an EGR cooler, the EGR cooler installed in an engine. The method comprises switchably flowing the exhaust gas through the exhaust-gas recirculation cooler according to a normal-calibration control mode when a temperature of the coolant is above a threshold temperature, and switchably flowing the exhaust gas through the exhaust-gas recirculation cooler according to an EGR-cooler restoring control mode (with a greater time-averaged flow of the exhaust gas) when the temperature of the coolant is below the threshold temperature.Type: GrantFiled: September 5, 2008Date of Patent: July 5, 2011Assignee: Ford Global Technologies, LLCInventors: Daniel Joseph Styles, David Curtis Ives

Publication number: 20110023800Abstract: A vee-engine has left and right cylinder banks have valve configurations that are mirror images of each other. The exhaust valves and associated exhaust ports are situated more toward the rear of the engine than the intake valves in any particular cylinder. With all the exhaust valves nearer the rear of the engine, the overall exhaust manifold runner length between the ports and the turbocharger is reduced relative to an engine with offset cylinder banks where exhaust valves in one bank are located nearer the front of the engine than exhaust valves of the other bank.Type: ApplicationFiled: July 31, 2009Publication date: February 3, 2011Applicant: FORD GLOBAL TECHNOLOGIES, LLCInventors: David Curtis Ives, Bradley David Opperman, Patrick Brian Morgan

Publication number: 20100058748Abstract: A method to dislodge an adherent residue in an EGR cooler, the EGR cooler installed in an engine. The method comprises flowing an exhaust gas through an adherent-residue bearing surface of the EGR cooler when a temperature of the adherent-residue bearing surface is below a dewpoint temperature of the exhaust gas, enabling water vapor from the exhaust gas to condense on the adherent-residue bearing surface, heating the adherent-residue bearing surface to above the dewpoint temperature of the exhaust gas, and enabling condensed water on the adherent-residue bearing surface to evaporate. Other embodiments provide a method to recirculate an exhaust gas from an exhaust port of an engine to an intake of the engine via an EGR cooler, and a related EGR system.Type: ApplicationFiled: September 5, 2008Publication date: March 11, 2010Applicant: FORD GLOBAL TECHNOLOGIES, LLCInventors: Daniel Joseph Styles, David Curtis Ives
