Method for controlling internal combustion engine equipped with cylinder disconnection device, involves identifying faulty cylinder from analysis of torque variation provided by engine to control isolation of faulty cylinder

摘要

The method involves diagnosing failure of a piloting system, and identifying a faulty cylinder from the analysis of torque variation provided by an internal combustion engine to control the isolation of the faulty cylinder, where the torque variation is estimated from the measurement of variation of angular velocity of a crankshaft of the internal combustion engine. The faulty cylinder is isolated while maintaining the disconnection of the faulty cylinder. An independent claim is also included for an internal combustion engine.
