FIELD: machine building.
SUBSTANCE: invention discloses various systems and methods for controlling premature ignition in a pressurized engine of a recently manufactured vehicle. One method comprises, at the pre-stage stage of the vehicle, controlling the supercharged engine during pre-calibration calibration with the first higher enrichment of the mixture in response to the premature ignition event. Preliminary calibration is deactivated at post-delivery stage, and supercharged engine operates with second, lower enrichment of mixture in response to premature ignition event.
EFFECT: prevention of deterioration of operational characteristics of vehicle after delivery to dealer centre.
