It has a structure in which a core body is housed in a cylindrical outer cylinder, and a catalyst material for exhaust purification is coated on the surface of the core body. As this core body, there is little resistance to the flow of exhaust gas,
Additionally, various structures have been developed to increase the area of contact with the exhaust gas. As such a core body, there is a so-called honeycomb core body, which is formed by winding a corrugated portion made of metal foil such as stainless steel into a corrugated shape and a flat plate portion overlapping each other. This kind of device uses a thin metal foil, so it has the characteristic that there is little resistance during the flow of exhaust gas.
ところで、従来の排気浄化装置は、車体の床下に取付け
られ、排気管の途中に接続されていた。By the way, conventional exhaust gas purification devices are installed under the floor of a vehicle body and connected to the middle of an exhaust pipe.
このため、排気の温度が低下し、排気の浄化効率が低下

排気口に接続し、この排気浄化ｆｉｌを排気マニホルド
として兼用することが好ましい。In order to eliminate such problems, it is preferable to provide this exhaust gas purification device as close to the exhaust port of the engine as possible so that high-temperature exhaust gas can flow therethrough. For this purpose, it is preferable to connect such an exhaust purification device directly to the exhaust port of the engine, and to use this exhaust purification filter also as an exhaust manifold.
しかし、このようにこの排気浄化装置をエンジンの近傍

However, in order to manufacture such a curved pipe-shaped exhaust gas purification device, it is naturally necessary to make the core body into a curved shape. However, if this core body is made into a bent shape, its manufacture becomes extremely troublesome.
また、上記のようなハニカムコア体は、その構造上屈曲
