Description
図6(a)〜(c)は、それぞれ排ガス成分浄化触媒材の構造を模式的に示す図である。
以下、PMを捕集するためのパティキュレートフィルタの構造について説明する。
={ガス流速(L/h)×[(CO+CO2)濃度(ppm)/(1×106)]}×12(g/mol)/22.4(L/mol)
上記所定時間毎のカーボン燃焼速度に基づいてカーボン燃焼量積算値の経時変化を求め、カーボン燃焼率が0%から90%に達するまでに要した時間とその間のカーボン燃焼量の積算値とからカーボン燃焼速度(フィルタ1Lでの1分間当たりのPM燃焼量(mg/min-L))を求めた。結果を表1の最右欄及び図12〜図14に示す。
