300cpsiのセル密度と12/1000インチ(約0.3mm)のウォール厚さを持つ5.66×3インチのコーディエライトウォールフローフィルタ基材が0.8g/in3のウォッシュコートの含有量及び80g/ft3のパラジウム含有量を有するTWCコーティング物質でコーティングされた。65%の細孔率で38マイクロンの平均細孔サイズ、62%の細孔率で20マイクロンの平均細孔サイズ及び52%の細孔率で15マイクロンの平均細孔サイズを有する3つの細孔構造が比較された。各フィルタはオーブンで980℃で4時間熱水的に加熱され、1.4Lの直接噴射ガソリンエンジンを有するユーロ4乗用車でアンダフロア位置に設置し、近接-結合位置(即ち、フィルタの上流側)に位置する流動貫通基材モノリス上にコーティングされる全体的に形成されたTWCを備える。各フィルタは3MVEG-Bサイクルの最低を通って評価され、基準システムに対する排気ガス粒子数の減少を測定し、アンダフロアフィルタは同一のウォッシュコートとパラジウムの含有量で流動貫通基材モノリス上にコーティングされたTWCに交換され、背圧差は近接-結合TWCの上流とフィルタ(又は基準触媒)の下流に装着されたセンサの間で決定された。表2に与えられた最大背圧の結果は、MVEG-Bサイクルを3回繰り返して得た背圧である。
20マイクロンの平均細孔サイズと62%の細孔率を有する4.66×4.5インチ、300/12コーディエライトウォールフローフィルタ基材が0.8、1.6及び2.4g/in3のウォッシュコート含有量である各TWCコーティング物質でコーティングされた。各サンプルは、85g/ft3の貴金属含有量(Pd:Rh16:1)を有する。各フィルタは、オーブンで980℃で4時間熱水的に加熱され、1.4Lの直接噴射ガソリンエンジンを有するユーロ4乗用車で近接-結合位置に設置された。各フィルタは3MVEG-Bサイクルの最低を通って評価され、基準触媒に対する排気ガス粒子数の減少を測定し、近接-結合フィルタは同一のウォッシュコートと貴金属含有量で流動貫通基材モノリス上にコーティングされたTWCに交換され、背圧差と気体HC、CO及びNOx排気ガスに対する転換効率は、フィルタ(又は基準触媒)の上流と下流に装着されたセンサの間で決定された。非メタン炭化水素(NMHC)だけの転換率が表3に記載される(ユーロ6のためのNMHCは100mg/kmの全体炭化水素排出の制限内である68mg/kmである)。
300cpsiのセル密度と約0.3mmのウォール厚さを持つ4.66×4.5インチ、300/12コーディエライトウォールフローフィルタ基材が1.6g/in3のウォッシュコート含有量と85g/ft3の貴金属含有量(Pd:Rh16:1)でTWCコーティング物質でコーティングされた。65%の細孔率として38マイクロンの平均細孔サイズ、62%の細孔率として20マイクロンの平均細孔サイズを有する2つの細孔構造が比較された。より小さな細孔サンプルは評価されていないが、これは実施形態2の結果から背圧がこのテストでユーロ4乗用車に対してあまりにも大きいことが予想されたためである。各フィルタは、オーブンで980℃で4時間熱水的に加熱され、1.4Lの直接噴射ガソリンエンジンを有するユーロ4乗用車で近接-結合位置に設置された。各フィルタは、3MVEG-Bサイクルの最低を通って評価され、基準触媒に対する排気ガス粒子数の減少を測定し、近接-結合フィルタは、同一のウォッシュコートと貴金属含有量で流動貫通基材モノリス上にコーティングされたTWCに交換され、背圧差と気体HC、CO及びNOx排気ガスに対する転換効率は、フィルタ(又は基準触媒)の上流と下流に装着されたセンサの間で決定された。非メタン炭化水素(NMHC)だけの転換率が表4に記載される。

13マイクロンの平均細孔サイズと48%の細孔率を有し、5/1000インチのセルウォール厚さを有し、18×60mm、360cpsi(360/5)のコーディエライトウォールフローフィルタ基材が0.4及び0.8g/in3のウォッシュコート含有量のTWCコーティング物質でコーティングされた。各サンプルは、85g/ft3の貴金属含有量(Pd:Rh16:1)を有する。更に高いウォッシュコート含有量は、評価されていないが、これはこのテストでユーロ4乗用車に対して結果背圧があまりにも大きいことが予想されたためである。フレッシュ(即ち、un-aged)フィルタが1.4Lの直接噴射ガソリンエンジンを備えるユーロ4乗用車で近接-結合位置に設置された。各フィルタは3MVEG-Bサイクルの最低を通って評価され、基準触媒に対する排気ガス粒子数の減少を測定し、近接-結合フィルタは、同一のウォッシュコートと貴金属含有量で流動貫通基材モノリス上にコーティングされたTWCに交換され、背圧差と気体HC、CO及びNOx排気ガスに対する転換効率は、フィルタ(又は基準触媒)の上流と下流に装着されたセンサの間で決定された。非メタン炭化水素(NMHC)だけの転換率が表6に記載される。
2.0Lの直接噴射ガソリンエンジンを備え、近接-結合位置で流動貫通基材モノリスにコーティングされた全体の形成TWCが装着されたユーロ5乗用車がMVEG-BとFTP(Federal Test Procedure)75ドライブサイクルにかけてテストされた。MVEG-Bドライブサイクルにかけて発生した粒子の数は、PMPの手順に従って測定された。FTP75ドライブサイクルにかけて発生した粒子性物質の質量は、次の標準プロトコルに測定された。0.8g/in3のウォッシュコートの含有量と20g/ft3の貴金属含有量(Pd:Rh3:1)のTWCコーティング物質でコーティングされた12マイクロンの平均細孔サイズと55%の細孔率を有する125×120mm、300/12のコーディエライトウォールフローフィルタがアンダフロア位置(即ち、流動貫通基材モノリスの下流側)に設置された。粒子質量と数の測定は繰り返された。
本発明は、活動的な三元触媒とフィルタモデルを用いる。前記モデルは、キネティック(kinetic)反応係数、基材とウォッシュコート特性及び車両で触媒温度と後部排気管の排気ガスを予想するためにユーロピアンMVEG-B排気ガステストから実証的に測定されたエンジン-アウト排気ガス温度と排気ガス成分の濃度を用いる。この実験のために、ユーロ5の1.4Lの直接噴射ガソリン車両から出るエンジン-アウト排気と温度が入力データとして用いられ、アンダフロア三元触媒コーティングされたガソリンフィルタに次いで近接-結合流動貫通三元触媒を含むシステムをモデリングした(300cpsi、20マイクロンの平均細孔直径、64%の細孔率、原形断面、118.4mmの直径及び114.3mmの長さ、2.4gin-3のウォッシュコート含有量、85gft-3で16Pd:Rhを有するセラミックウォールフローフィルタ)。商業的に利用可能な1.25L(400cpsi、118.4mm直径の原形断面、114.3mm軸方向の長さ)近接-結合三元触媒(エンジン排気量の90%、60gft-3で19Pd:Rh、3.5gin-3ウォッシュコート含有量)が同一の白金族金属組成物と含有量及び基材セル密度と直径を有するが、長さが1.25L触媒の半分(57.15mm)である0.625L触媒(エンジン排気量の45%)と比較された(基本的に125L近接-結合三元触媒がその軸方向の長さに半分に切られる)。
