Publication number: 20160245204Abstract: Methods and systems are provided for estimating an exhaust air/fuel ratio based on outputs from an exhaust oxygen sensor. In one example, a method may include adjusting engine operation based on an air-fuel ratio estimated based on an output of the exhaust oxygen sensor and a learned correction factor. For example, the oxygen sensor may operate in a variable voltage mode in which a reference voltage of the oxygen sensor may be adjusted between a lower first voltage and a higher second voltage, and the learned correction factor is based on the second voltage.Type: ApplicationFiled: February 19, 2015Publication date: August 25, 2016Inventors: Daniel A.

Publication number: 20090241925Abstract: Air/fuel imbalance monitoring systems and methods for monitoring air/fuel ratio imbalance of an internal combustion engine having a plurality of engine cylinders are provided herein. An example of the method may include routing exhaust gas from a first group of cylinders to an exhaust gas oxygen sensor, and during selected operating conditions, indicating that air/fuel of at least one cylinder in the first group is imbalanced based on a response of the exhaust gas oxygen sensor at frequencies at or above firing frequency of the cylinders in the first group. An example of the system may include an exhaust gas oxygen sensor positioned in such a way that exhaust gas from the group of engine cylinders are routed to the exhaust gas oxygen sensor, and a controller configured to during selected operating conditions, indicate that air/fuel of at least one cylinder in the group is imbalanced based on a response of the exhaust gas oxygen sensor at frequencies at or above firing frequency of the cylinders in the group.Type: ApplicationFiled: March 25, 2008Publication date: October 1, 2009Applicant: FORD GLOBAL TECHNOLOGIES, LLCInventors: Ken John Behr, Has R.
