Document Type and Number:
WIPO Patent Application WO/2011/001825
Kind Code:
A1
Abstract:
A PM sensor is provided which is simple in structure but capable of precisely detecting an amount of PM accumulated in a DPF. In a diesel particulate filter (DPF) (3) having multi-aperture filter body (2) partitioned by many division walls, two electrodes (4a, 4b) form a capacitor with one or more division walls therebetween, and at least one (4b) of the two electrodes (4a, 4b) is formed by a wire rod, and the amount of PM collected in the DPF (3) is detected from the electrostatic capacity of the capacitor.
