Things. Background art
従来より、 自動車ゃォートバイなどのような車両閩係においても排気ガスの浄 化促進が図られているが、 近年は環境問題への意識の高まりにより、 大気汚染の 元凶として、 特にこれら車両関係の排気ガス浄化処理に対する関心が高まってき ている。  Conventionally, the purifying of exhaust gas has also been promoted in vehicle-related businesses such as automobiles and motorcycles, but recently, due to the increasing awareness of environmental issues, air pollution has been a major cause of air pollution. There is growing interest in exhaust gas purification.
上記した車両関係より排出される排気ガスは、 周知のように一酸化炭素 （C O ) , 窒素酸化物 （N O ) , 炭化水素 （H C ) , 鉛 （P b ) などの有害物質が含有 されており、 これらの有害物質を低減化して大気中に少しでも清浄な排気ガスを 排出すべく鋭意、 研究，努力が図られている。  As is well known, the exhaust gas emitted from the above-mentioned vehicles contains harmful substances such as carbon monoxide (CO), nitrogen oxides (NO), hydrocarbons (HC), and lead (Pb). Efforts, research, and efforts have been made to reduce these harmful substances and to emit even a little exhaust gas into the atmosphere.
しかして、 従来の排気ガス浄化装置としては、 エンジンルーム側 （排気ガスの 排出時の上流側） においてその処理を行なおうとするものが殆どであり、 必然的 に浄化機構が複雑化するという問題があると共に、 車体を改造して後付けをする ことはできないという問題を有している。  However, most of the conventional exhaust gas purifying devices attempt to perform the treatment on the engine room side (upstream side when exhaust gas is discharged), which inevitably complicates the purifying mechanism. In addition, there is a problem that the body cannot be modified and retrofitted.
