【発明の名称】内燃機関の排ガスを浄化するための蜂の巣構造体
Document Type and Number:
Japanese Patent JP2672111
Kind Code:
B2
Abstract:
Honeycomb bodies for cleaning the exhaust gases of internal combustion engines function as carrier for a wash coat impregnated with a noble metal. The known honeycomb bodies exhibit square conduit cross sections with a cross-sectional area of approximately 1.1x1.1 mm2. The small cross sections result in high flow resistances which are amplified even more by deposits of rather thick layers of wash coat in the corner areas. A considerable diminution of the flow resistances is achieved without reducing the amounts of harmful substances converted while saving honeycomb material if the honeycomb bodies (1) comprise individual conduits (2) which exhibit a ratio of width (3) to height (4) of 1.5 to 15.
