Abstract
A multi-line exhaust system has at least two exhaust lines which are substantially separate from one another and at least one measurement sensor for measuring at least one characteristic variable of the exhaust gas. In which system, the at least one measurement sensor can be brought into contact with at least two exhaust lines. In such an exhaust system the measurement sensor determines at least one characteristic variable of the exhaust gas in two or more different exhaust lines, so that the outlay required to monitor the at least one characteristic variable in a plurality of exhaust lines can be significantly reduced compared to if a measurement sensor is formed in each exhaust line.
