Abstract

The invention includes a ceramic catalytic converter substrate having cell walls with rounded corners. The cell walls have a honeycomb or hexagonal shape with rounded corners. The cell walls may be manufactured with very thin walls from 0.003-0.005 inches. There is provided increased structural strength of the substrate due to rounded corners of cell walls into honeycomb or hexagonal shaped walls. The rounded corners of the cell walls also substantially increases the strength of the substrate. The honeycomb shape of the substrate uniformly dissipates any force applied to the substrate. The rounded corner cell walls allows a more uniform deposit of washcoat and precious metals and reduces the amount of precious metals necessary which coat the substrate along with reducing additional backpressure of the exhaust system caused by the washcoat which normally forms fillets in corners of squared-celled substrates.
