Control apparatus and method for interrupting regeneration of a particle filter of a Diesel engine

摘要

The regeneration interruption method uses detection of the mass air flow (MAFmes) and the intake pressure (MAPmes), with regulation of an exhaust gas feedback valve (3) for obtaining a required mass air flow (MAFdes) calculated from the engine revs (n), the fuel feed (Fq) and the air/fuel ratio (A/Fdes) and regulation of an intake throttle valve (2) for obtaining a required intake pressure (MAP mod). The latter is provided by summation of a base air intake pressure (MAPdes) with a pressure correction dependent on the difference between the actual and required mass air flows. An Independent claim for a regulation device for interrupting the regeneration of a particle filter in the exhaust gas system of a diesel engine is also included.
