Patent number: 9903788Abstract: An apparatus includes an electroactive polymer member and a first electric terminal and a second electric terminal. The electroactive polymer member has a free portion configured to change position relative to a fixed portion in response to an external stimulus corresponding to at least one of a flow parameter or a fluid parameter. The first electric terminal and the second electric terminal are coupled to the electroactive polymer member. The first electric terminal and the second electric terminal provide an electrical signal in response to the change.Type: GrantFiled: April 28, 2011Date of Patent: February 27, 2018Assignee: BOARD OF TRUSTEES OF MICHIGAN STATE UNIVERSITYInventors: Guoming G Zhu, Xiaobo Tan, David Ling-Shun Hung

Methods Of Controlling An Internal Combustion Engine Including Multiple Fuels And Multiple Injectors
Publication number: 20110010074Abstract: A method for controlling the start of combustion and peak burn rate of an internal combustion engine system on a cycle-to-cycle basis including multiple direct fuel injectors, multiple indirect fuel injectors, and multiple liquid fuels. The actual start of combustion and actual peak burn rate are calculated using in-cylinder pressure or ionization. A predetermined start of combustion and a predetermined peak burn rate are selected. The start of combustion and peak burn rate control algorithm includes controlling a fuel ratio, an injection ratio, and a residual gas recirculation ratio. A predetermined fuel ratio, a predetermined injection ratio, and a predetermined residual gas recirculation are calculated by combining feed forward ratios and closed loop control ratios corresponding to the three ratios. The predetermined ratios are employed so that the system achieves the predetermined start of combustion and predetermined peak burn rate.Type: ApplicationFiled: July 9, 2009Publication date: January 13, 2011Applicant: VISTEON GLOBAL TECHNOLOGIES, INC.Inventors: David Ling-Shun Hung, Guoming George Zhu -
Patent number: 7712451Abstract: A fuel injection system for an internal combustion engine is disclosed, the fuel injection system including a plurality of injectors, wherein each of the injectors is adapted to inject at least one of an alternative fuel and a fossil fuel over a full range of operating conditions of the engine.Type: GrantFiled: May 7, 2008Date of Patent: May 11, 2010Assignee: Visteon Global Technologies, Inc.Inventors: David Ling-Shun Hung, George Guoming Zhu

Publication number: 20090200403Abstract: A fuel injector having a nozzle with depressions for increasing fluid turbulence and preventing deposit build up within the injector to increase performance, longevity and fuel economy.Type: ApplicationFiled: February 8, 2008Publication date: August 13, 2009Inventors: David Ling-Shun Hung, Vivek A. Jairazbhoy, David L. Porter
-
Publication number: 20090090794Abstract: A low pressure fuel injector capable of atomizing fuel at relatively low pressure is configured to have reduced hydraulic resistance. Reduction in the hydraulic resistance minimizes the pressure drop within the fuel injector and thereby improves atomization of the fuel for improved fuel economy and performance, and decreased emissions.Type: ApplicationFiled: October 4, 2007Publication date: April 9, 2009Applicant: Visteon Global Technologies, Inc.Inventors: David Ling-Shun Hung, Vivek A. Jairazbhoy, David L. Porter
