この発明は、内燃機関の排気ガス浄化等に用い
る触媒体の保持装置の改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a catalyst holding device used for purifying exhaust gas of an internal combustion engine.
自動車等の内燃機関では、排気系に触媒体を装

低下する。 In internal combustion engines such as automobiles, a catalyst body is installed in the exhaust system to purify exhaust gas. The catalytic body is generally made of ceramic with a large number of small holes in a honeycomb shape and a catalytic agent adhered to it, and is susceptible to vibration. Then, wrap a cushion material such as steel wool around the catalyst body and insert it into the holding cylinder.
Protects the catalyst from vibration. However, some of the exhaust gas passes through the cushion material,
Since some substances do not pass through the catalyst, the purification efficiency decreases.
この発明は、かかる点に鑑み改善したもので、
以下図面に示す本発明の実施例について説明す

Embodiments of the present invention shown in the drawings will be described below.

うしたものを、保持筒７内に挿入する。 FIGS. 1 and 2 show an embodiment of the present invention, in which a cushion material 3 is provided in which steel wool 1 made of heat-resistant steel and silica wool 2 made of glass fiber treated with silica are laminated to form a plate. . The cushion material is cut to a size to be wrapped around the outer periphery of the honeycomb-shaped catalyst body 4. At that time, the side edge 5 side is cut diagonally. When this cushion material 3 is wrapped around the outer periphery of the catalyst body 4 and the side edges 5 are abutted, the abutting surfaces become oblique. Then, a cushion piece 6 formed into an annular shape is applied to both ends of the outer periphery of the catalyst body 4. These items are inserted into the holding cylinder 7.

る。 3 and 4 show another embodiment of the present invention, in which a cushion material 3 made of laminated steel wool 1 and glass wool 2 is provided, and a large cushion material 3 is wound around the outer periphery of a catalyst body 4. Cut it right. At this time, both ends of the cushion material 3 are cut diagonally so that when the cushion material 3 is wound, the cut parts overlap. Annular cushion pieces 6 are placed on both ends of the outer periphery of the catalyst body 4 and inserted into a holding cylinder 7.
作用について説明する。 The effect will be explained.

して、浄化効率がよくできる。 When the exhaust gas flows inside the holding cylinder 7, it passes through the honeycomb-shaped catalyst body 4, comes into contact with the catalyst agent, and is purified. The cushion material 3 is made by laminating steel wool 1 and siliglas wool 2, and the siliglas wool 2 has a high density and allows less exhaust gas to pass through. Furthermore, when the cushion material 3 is wrapped around the catalyst body 4, the side edges 5 are either abutted diagonally or cut diagonally and overlapped, so there is less gap at the butt part, and the exhaust gas leakage can be reduced. Furthermore, Siliglas wool has high heat retention properties. In this way, purification efficiency can be improved.

つので、この面でも浄化効率が向上する。 As explained above, the present invention provides a cushion material in which steel wool and siliglas wool are laminated, and either ends of the cushion material are cut diagonally and butted together, or cut diagonally and overlapped to form a catalyst body. Because it is wrapped and inserted into the holding cylinder, the density of the siliglas wool is high, and the gap between the overlapped parts can be reduced by butting or cutting, which reduces the possibility of exhaust gas leaking through. It is possible to improve the purification efficiency. In addition, siliglas wool has high heat retention properties and maintains the catalyst body at a high temperature, so the purification efficiency is improved in this aspect as well.
