Catalytic converter arrangement for exhaust gas system of motor vehicle IC engine

摘要

The catalytic converter arrangement for an Otto-cycle IC engine, in which exhaust gases are guided in first and second feed lines to the catalytic converter, has the rotationally symmetrical honeycomb body (3) with a first passage line (1) and a second passage line (2) which are at least approximately gas-tightly closed off relative to each other and which each have a number of passages connecting an intake end (14) of the honeycomb body and an outlet end (15) of the honeycomb body (3). The first and the second feed lines are connected at the intake end to the first and second passage lines respectively. The first passage line (1) is disposed coaxially in the interior of the second passage line (2) and the hydraulic diameters of the first passage line (1) and the second passage line (2) are approximately equal.
