|1. (WO2018219736) EXHAUST GAS PIPE ASSEMBLY FOR AN INTERNAL COMBUSTION ENGINE|
|Applicants:||CONTINENTAL AUTOMOTIVE GMBH
|Title:||EXHAUST GAS PIPE ASSEMBLY FOR AN INTERNAL COMBUSTION ENGINE|
The invention relates to an exhaust gas pipe assembly (100) for an internal combustion engine which comprises: an exhaust gas pipe (110) extending substantially along an longitudinal axis (101), which exhaust pipe is designed at least partially to guide exhaust gas from the internal combustion engine; an opening (130) provided in the exhaust gas pipe (110), which opening is arranged substantially radially to the longitudinal axis (101); a coupling element (112) arranged on the exhaust gas pipe (110), which element extends at least partially in or over the opening (130); a shield housing (140), which is mounted from the outside on the exhaust gas pipe (110) in such a manner that it substantially completely encloses the opening (130); and a waveguide (150) which is coupled to the coupling element (112) and is designed to inject electromagnetic waves into the shield housing (140) by means of the coupling device (112) in such a manner that the electromagnetic waves are propagated through the opening (130) into the exhaust gas pipe (110).
