Verdichtersaugen-Steuerungsverfahren

摘要

In a method and a system for controlling a combustion engine powering a motor vehicle having a turbo charger and an EGR system the control system is adapted to detecting a strong negative fuel rate exceeding a pre-determined threshold value (301), and controlling the EGR valve to a more open position (303) for letting charge gas exit through the EGR path thereby reducing the risk for surging in the compressor of the turbo charger.
