| titleOfInvention | Method and system for exhaust gas recirculation estimation via an exhaust gas oxygen sensor |
| abstract | Methods and systems are provided for estimating an amount of Exhaust Gas Recirculation (EGR) from an exhaust passage into an intake passage of an engine system by operating an exhaust gas oxygen sensor in a Variable Voltage (VV) mode. In one example, a method includes adjusting engine operation based on an EGR amount estimated based on an output of an exhaust gas oxygen sensor and a learned correction factor based on a second voltage during operation of the exhaust gas oxygen sensor in a VV mode where a reference voltage of the exhaust gas oxygen sensor is adjusted from a lower first voltage to a higher second voltage. In this way, the exhaust gas oxygen sensor may be used to correct for changes due to changing fuel composition and ambient humidity, and also to estimate the amount of EGR recirculated in the system, thereby enhancing engine fueling and EGR control. |
