Treatment of exhaust gas - involves afterburner and catalyst together with flame barrier to impede gas flow

摘要

The arrangement is for handling the exhaust gas of an IC engine. It comprises a catalyst (9) and an afterburner (8) arranged in front of it. The catalyst has a carrier body (10) for the catalytic layer exposed to through flow and is surrounded by a housing (18), upstream of which is provided the combustion chamber (12) of the afterburner, also surrounded by the housing, with a flame barrier (16) to prevent the free flow of gas. USE/ADVANTAGE - Exhaust system which reduces harmful emissions during the IC engine warm-up phase.
