Abstract
A method for controlling an internal combustion engine for regenerating an exhaust gas purifying mechanism arranged on an exhaust line of the engine during a phase of regeneration of the purifying mechanism. The method analyzes an exhaust gas composition solely downstream of the purifying mechanism and develops, based on the analysis, a control signal for the engine to modify an exhaust gas composition upstream of the purifying mechanism.
