A lambda probe (8) is positioned in the exhaust gas line before the oxidation catalyst. Preferred Features: An adjustable return valve is arranged in the return line. A sulfur trap (7) is arranged in the exhaust gas line in the flow direction before the oxidation catalyst. The lambda probe is arranged in the flow direction before the sulfur trap.",
