触媒コンバータでの圧力損失は、排気システム全体の内でも最も大きな部分の一つで、出力低下や燃費悪化を招く。また、触媒担体入口での速度分布の不均一は、温度の不均一をもたらし、排気ガス浄化効率を低下させる。そのため本研究では、速度分布不均一性と圧力損失を同時低減することを目的に、新しい手法を提案する。
In the automotive exhaust system, a catalytic converter is one dominant component to produce pressure drop, which induces engine-power loss and fuel-efficiency reduction. 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.
