Method and device for monitoring a particulate filter


A method for monitoring a particulate filter in the exhaust duct of an internal combustion engine operated with gasoline, as a device for implementing the method are described. A first exhaust-gas temperature is determined upstream of the particulate filter and a second exhaust-gas temperature is determined downstream from the particulate filter, and a presence and/or a correct functioning of the particulate filter is inferred from a difference between the first and the second exhaust-gas temperature or from a differing time characteristic curve of the first and the second exhaust-gas temperature..

Exhaust purification device for internal combustion engine


Micropore zones zmi are defined at upstream sides of partition walls 72 of a particulate filter and macropore zones zma are defined at downstream sides of partition walls. The pore size of the partition walls at the micropore zones is set so that the particulate matter and the ash can be trapped by the partition walls at the micropore zones, while the pore size of the partition walls at the macropore zones is set so that the ash can pass through the partition walls at the macropore zones.

Fan system for an engine housing structure of an internal combustion engine


A pan system suitable for an engine housing structure of an internal combustion engine has two inner and outer pans with bottoms and upright walls which are placed inside one another and are trough-shaped in cross section. The inner pan accommodates lubricating oil of the internal combustion engine and the outer pan with the bottom and the upright walls runs at least in certain areas at a distance from the bottom and the walls of the inner pan so as to result in a channel-like intermediate space which contains cooling liquid of the internal combustion engine for affecting the temperature of the inner pan.
