Abstract

본 발명은 통체(21)와, 상기 통체(21)내에 수납되어 적어도 프론트부 및 리어부가 통체(21)에 고착된 다공판으로 이루어지고, 이 다공판에 촉매금속을 담지한 내연기관의 배기정화장치(12)에 있어서, 다공판은 Cr:16-18%, C:0.12% 이하, Mn:1%이하, Si: 0.75% 이하의 페라이트계 스테인레스 강판으로 이루어지고, 또한 통체(21)는 다공판의 선팽창계수보다도 큰선팽창계수를 가지는 스테인레스 강판으로 이루어지는 것을 특징으로 하는 내연기관의 배기정화장치이다.The present invention consists of a cylinder 21 and a porous plate housed in the cylinder 21 and fixed to at least the front and rear portions of the cylinder 21, and purifying exhaust gas of the internal combustion engine on which the catalytic metal is supported. In the apparatus 12, the porous plate is made of a ferritic stainless steel sheet having Cr: 16-18%, C: 0.12% or less, Mn: 1% or less, Si: 0.75% or less, and the cylinder 21 An exhaust gas purifying apparatus for an internal combustion engine, comprising a stainless steel sheet having a coefficient of linear expansion larger than that of the stencil.

이와 같이 구성된 본 발명의 배기정화장치는 다공판보다도 상대적으로 저온이 되는 통체를 고온이 되는 다공판의 재료보다도 선팽창계수가 큰 재료로 구성하였으므로, 다공판과 통체와의 열팽창량이 대체로 같아진다.The exhaust purification apparatus of the present invention configured as described above has a cylinder having a relatively lower temperature than that of the porous plate made of a material having a linear expansion coefficient larger than that of the porous plate having a high temperature, so that the amount of thermal expansion between the porous plate and the cylinder is substantially the same.

이 때문에, 다공판과 통체 사이의 고정부분에 작용하는 열응력이 작아도 되므로, 배기정화장치의 내구성이 향상된다.For this reason, since the thermal stress acting on the fixed part between a porous plate and a cylinder may be small, durability of an exhaust purification apparatus improves.
