Publication number: 20110219750Abstract: The present invention relates to an exhaust gas purifying apparatus for an internal combustion engine. An object of the invention is to reduce the amount of particulate matter that flows out from a catalytic converter that continuously burns particulate matter contained in an exhaust gas. The exhaust gas purifying apparatus for an internal combustion engine of the present invention includes a catalytic converter that continuously burns particulate matter contained in an exhaust gas; particle amount acquisition means that acquires an inflow amount of particulate matter to the catalytic converter; and particle amount increase means that, when an acquired inflow amount of particulate matter is less than a predetermined threshold value ?, changes a value of a control parameter of the internal combustion engine in a direction such that the inflow amount of particulate matter to the catalytic converter increases.Type: ApplicationFiled: February 26, 2009Publication date: September 15, 2011Applicant: Toyota Jidosha Kabushiki KaishaInventors: Kenji Sakurai, Shigeki Miyashita

Publication number: 20110219752Abstract: A regeneration system includes a particulate matter (PM) filter. The PM filter has an upstream end that receives an exhaust gas from an engine. An air pump circuit directs ambient air to a first exhaust conduit upstream from the PM filter. A control module determines a current soot loading level of the PM filter. The control module also at least one of operates the engine in a rich mode and activates an air pump of the air pump circuit when the current soot loading level is greater than a predetermined soot loading level.Type: ApplicationFiled: March 12, 2010Publication date: September 15, 2011Applicant: GM GLOBAL TECNOLOGY OPERATIONS, INC.Inventors: Eugene V. Gonze, Halim G. Santoso, Michael J. Paratore, JR.
