Abstract

An arrangement of a catalytic converter in an exhaust system of an internal combustion engine which can be operated with fuel containing manganese, wherein the catalytic converter is arranged in the exhaust system in a flow path of an exhaust gas of the internal combustion engine through the exhaust system, and wherein a sacrificial disc which is permeable to exhaust gas is arranged in the exhaust system upstream of the catalytic converter in the flow direction of the exhaust gas. When the exhaust-gas back pressure becomes too high for normal internal combustion engine operation owing to manganese deposits, it is necessary to exchange not the catalytic converter but rather only the cheap sacrificial disc.
