FIELD: fuel combustion devices.
SUBSTANCE: disclosed are methods and systems for identifying and reducing imbalance of air-fuel ratio of cylinder. In one example, the method can comprise identifying an unbalance-based cylinder based on readings of two oxygen content sensors, located upstream and downstream of the catalytic neutraliser in the outlet channel, and reducing imbalance based on the error value determined from the readings.
EFFECT: technical result is detection and suppression of imbalance between cylinders.
