Abstract:
A method for determining the state of loading of a particle filter in an exhaust system of a turbocharged internal combustion engine is provided. To determine the state of loading, a position of a control mechanism of the turbine of the exhaust turbocharger is detected and compared with the position during operation of the internal combustion engine with the same operating parameters with the particle filter unladen. An air mass meter is provided in order to be able to distinguish a change in the pressure situation at the turbine of the exhaust turbocharger due to a rise in the exhaust gas backpressure owing to increasing loading of the particle filter from a change in the pressure situation owing to leakage of the air supply system. An internal combustion engine having a control unit which is configured to carry out such a method is also provided.

Claim (Index 12):
An internal combustion engine, comprising:\n an air supply system; an exhaust system; combustion chambers; an exhaust turbocharger having a compressor disposed in said air supply system and having a turbine disposed in said exhaust system, said turbine driving said compressor in order to compress fresh air fed to said combustion chambers; a particle filter disposed in said exhaust system downstream of said turbine of said exhaust turbocharger; a control device for determining one of a position of a control mechanism of said turbine and a rotational speed of a speed sensor of said turbine, said control device being disposed at said turbine; and a control unit configured to execute a machine-readable program code such that said control unit is configured to compare one of a determined position of said control device and a determined rotational speed of said turbine with one of a position of said control device and a rotational speed of said turbine in a same operating state and with said particle filter unladen, and such that said control unit is configured to calculate a state of loading of said particle filter from one of the determined position of said control device and the determined rotational speed of said turbine.
