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: 7840458Abstract: A method and apparatus for collecting information about an event in which a user accesses the Internet through the system of a first Internet Service Provider with whom the user does not have an account. The apparatus includes a first server that creates a record of the user's Internet usage and sends the record to a second server. The second server collects records from a plurality of Internet Service Providers and forwards the records to a third server on a regular basis. The third server processes the data in the plurality of records and generates a report showing how much money the first Internet Service Provider is owed for allowing the user to access the Internet through the system of the first Internet Service Provider.Type: GrantFiled: September 24, 2007Date of Patent: November 23, 2010Assignee: iPass Inc.Inventors: Lynn Y. Liu, Xiaomei Guan, Michael E. Hayden, David Ling
