  • Methods and systems for individual cylinder air-fuel ratio control in a combustion engine
    Patent number: 10215115
    Abstract: Methods and systems are provided for controlling individual cylinder air-fuel ratio (AFR) in a combustion engine. In one example, a method may include measuring a high-frequency exhaust gas composition, parsing the measured high-frequency exhaust gas composition to determine a first cylinder-specific component of the high-frequency exhaust gas composition, estimating an air-fuel ratio (AFR) based on the first cylinder-specific component of the measured high-frequency exhaust gas composition, and correcting the estimated AFR by subtracting intercylinder exhaust gas interactions from the estimated AFR.
