摘要:
A diesel particulate filter (“DPF”) including vertically and horizontally stacked cells in which all of vertical and horizontal sides are surrounded by walls formed of a porous material, and sealing end faces of the cells alternately vertically and horizontally are provided with first and second electrodes. In a particulate matter (“PM”) sensor in which a PM deposit quantity of the DPF is detected by a capacitance of a capacitor formed by the first and second electrodes, among open cells, the first electrodes are inserted into the open cells arranged in a line in a diagonal direction, and the second electrodes are inserted into the open cells arranged in a line in the diagonal direction and including the open cells secondarily adjacent to each of the open cells into which the first electrodes are inserted.
