Title:
露出した放熱面を備えた触媒コンバータ用担体
Document Type and Number:
Japanese Patent JP4278862
Kind Code:
B2
Abstract:
A catalyst carrier body for an exhaust system of an internal combustion engine, especially of a motor vehicle, includes a matrix having an inflow surface, an outflow surface, a periphery, and a multiplicity of catalytic surfaces around which exhaust gas can flow. The catalytic surfaces have front regions and form flow-through passages. The outflow surface has a shape, at least in an inner region thereof, causing the front regions to be exposed and not covered outwardly, toward the periphery, by others of the catalytic surfaces. The exposed front regions have lengths, at least in a partial region of the outflow surface, amounting to from 55% to 90% of the length of the flow-through passages, for increasing an outward dissipation of heat. As a result, outwardly open heat radiating areas are guaranteed for an improved emission of heat to the surroundings or into the exhaust system.
