Title
(EN) PM SENSOR
(FR) DÉTECTEUR DE PARTICULES
(JA) PMセンサ
Abstract
(EN)
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 the two electrodes (4a, 4b) are concentrically arranged, and the amount of PM collected in the DPF (3) is detected from the electrostatic capacity of the capacitor.
(FR)
L'invention concerne un détecteur de particules de configuration simple mais capable de détecter avec précision une quantité de particules accumulées dans un FPD. Dans un filtre à particules diesel (FPD) (3) ayant un corps de filtre à ouvertures multiples (2) séparées par de nombreuses cloisons, deux électrodes (4a, 4b) forment un condensateur avec une ou plusieurs cloisons situées entre elles, et les deux électrodes (4a, 4b) sont disposées de manière concentrique. La quantité de particules collectées dans le FPD (3) est détectée d'après la capacité électrostatique du condensateur.
(JA)
 簡素な構成で正確にDPFに溜まったPMの量を検出することができるPMセンサを提供する。 多数の隔壁で仕切られた多孔状のフィルタ本体2を有するディーゼルパティキュレートフィルタ(DPF)3に、1個以上の隔壁を挟んでコンデンサを形成する2つの電極4a,4bを同心状に重ねて設置し、そのコンデンサの静電容量からDPF3に捕集されているPMの量が検出されるようにした。
