Publication number: 20070256406Abstract: A system and method for engine control and diagnostics are described. The engine system may include an engine having a catalyst in the exhaust system, the exhaust system further having an exhaust gas oxygen sensor upstream of the catalyst and downstream of the catalyst. In one example, the method may include during a first operating mode in which catalyst diagnostics are not carried out, adjusting air-fuel ratio based on both the upstream and downstream exhaust gas oxygen sensors, where air-fuel ratio adjustment responsiveness to the downstream sensor is reduced as the catalyst performance degrades; and during a second operating mode that includes catalyst diagnostics, adjusting air-fuel ratio based on at least the downstream exhaust gas oxygen sensor, where said air-fuel ratio adjustment responsiveness to the downstream sensor is temporarily increased from said reduction generated during the first operating mode.Type: ApplicationFiled: May 1, 2007Publication date: November 8, 2007Applicant: FORD GLOBAL TECHNOLOGIES, LLCInventors: Imad Hassan Makki, James Michael Kerns, Michael James Uhrich, Michael Igor Kluzner

Patent number: 6804951Abstract: A method for determining the effectiveness of a catalyst to remove emissions from the exhaust of an internal combustion engine. The method includes measuring an upstream time history of a signal produced by an exhaust gas oxygen sensor upstream of the converter and a time history of an exhaust gas oxygen sensor disposed downstream of the converter. The time histories vary between a lean air-fuel ratio signal level and a rich air-fuel ratio signal level. A time delay is determined between the upstream time history and the downstream time history during transitions in such time histories from the lean air-fuel ratio signal level to the rich air-fuel ratio signal level. The determined time delay is compared with a reference time delay to determine the efficiency of the converter. The converter is determined to be ineffective if the converter as been determined to be potentially ineffective and the time delay is determined to be less than the reference time delay.Type: GrantFiled: November 6, 2002Date of Patent: October 19, 2004Assignee: Ford Global Technologies, LLCInventors: David Robert Nader, Michael Igor Kluzner, Robert Eloy Gonzales, Robert Joseph Jerger, Ziad Zaghati
