In addition, non-uniformity of flow through a catalytic substrate causes non-uniform thermal distribution on the substrate, which causes low conversion efficiency. The present purpose is both to reduce the pressure loss and to improve the flow maldistribution, simultaneously. Namely, we have proposed a new type of the catalytic-converter-diffuser configuration, and measured its performance experimentally., application/pdf}, pages = {[108]--114}, title = {触媒コンバータの損失低減と分布特性改善の為の新手法}, volume = {49}, year = {2008}, yomi = {ヒラタ, カツヤ and オダ, リョウジ and タナカ, シンヤ and タニガワ, ヒロチカ and フナキ, ジロウ} }
