DIESEL PARTICULATE FILTER

摘要

PURPOSE:To efficiently reproduce a filter by uniformly heating the whole filter in regeneration of the filter. CONSTITUTION:Ceramic fibers are fed to a carding machine or a paper making machine to form a ceramic fiber deposit 1. The ceramic fiber deposit 1 is pinched from both sides by metal nets 3 serving as heaters for burning collected particulates to constitute a filter element 4. The filter element 4 is to form a particulate filter. A material having the ratio of 1.1 or above between the resistance value near 600 deg.C and the resistance value at the ordinary temperature is used for the material of the heater.
