Patent ID: 7721527

Claim:
A multi-line exhaust system, comprising: at least two first and second exhaust lines substantially separate from one another; at least one measurement sensor for measuring at least one characteristic variable of an exhaust gas, said measurement sensor being brought into contact with exhaust gas flowing within said at least two exhaust lines: at least one honeycomb body formed in said at least two exhaust lines, said at least one honeycomb body having a first end face, a second end face, and cavities formed therein, said cavities extending between said first and second end faces and at least partially allowing a fluid to flow through, and said at least one honeycomb body having at least two first and second flow regions closed off in an approximately gastight manner with respect to one another, said first and second flow regions each connected to a respective one of said first and second exhaust lines; a first separation device separating said first and second exhaust lines from one another and preventing exhaust gas guided by said first exhaust line from mixing with exhaust gas guided by said second exhaust line until the exhaust gases enter said at least one honeycomb body; and a second separation device separating said flow regions from one another.
