Abstract

A compact exhaust gas aftertreatment device for an internal combustion engine comprises a catalytic converter, wherein the catalytic converter comprises an encapsulating member, a pipe member, an exhaust gas guiding means and two catalytic converter substrates. The exhaust gas aftertreatment device provides very good exhaust gas mixing properties. Additionally, the exhaust gas guiding means is configured to withstand thermal stress due to exposure to hot exhaust gas emissions.
