<p>PURPOSE:To provide higher filter recovery efficiency for an exhaust gas particulate removing device for a diesel engine by arranging two filters in parallel. CONSTITUTION:A filter 3 has a filter cell 3a formed with a portion facing to another filter 4 longer than a portion parting from another filter 4. In this way, particulates which are trapped into the facing portion is increased, so that another filter 4 can be efficiently preheated by the quantity of heat generated when the filter 3 is recovered and the filter 4 can have higher recovery efficiency.</p> |
