Abstract
The invention relates to a method for interrupting the regeneration of a particulate filter in the exhaust gas system of a diesel engine to protect the filter against destructive overheating. In this case, an electronic control unit calculates a desired mass air mass flow rate (MAF ) based on engine speed (n), fuel supply (F ) to the engine, and air/fuel ratio (A/F ). A mass air flow rate regulator controls the position of an exhaust gas recirculation (EGR) valve as a function of the difference between the desired mass air mass flow rate (MAF ) and the measured mass air flow rate (MAF ). An intake manifold absolute pressure controller adjusts the position of an intake throttle valve as a function of the difference between the measured intake manifold absolute pressure (MAP ) and the modified intake manifold absolute pressure (MAP ). MAP is determined by a coordination module, based on the mass air flow rate error and other parameters.
