ABSTRACT:
There is disclosed a diesel particulate filter for collecting and burning particulates and exhaust gases of a diesel engine and a controlled device therefor. The diesel particulate filter includes a wire net of electric resistance metal fastened to a main filter to burn the particulates collected by the main filter in the exhaust gases of the diesel engine. There is included a bypass pipe which constitutes a sub-filter and which is disposed within a filter case. The bypass pipe is provided with an open-close valve in the vicinity of an inlet thereof. A cylindrical main filter made by laminating long fibers of ceramics is disposed between the bypass pipe and the filter case. The wire net of electric resistance metal for heating the main filter is fastened on one surface of the main filter for receiving the exhaust. A reinforcing net-like plate of a heat resistant metal is fastened on the other surface of the main filter for releasing the exhaust.
