17. An exhaust system for discharging exhaust gases through an exhaust passageway, emitted from a multi-cylinder combustion engine mounted on a motor vehicle, which system comprises:
-
a partition plate dividing the exhaust passageway into a plurality of juxtaposed exhaust passages and having a communicating hole defined therein; and an exhaust gas sensor positioned at a location close to the communicating hole and disposed diagonally relative to the partition plate so as to have a leading end for detecting a composition of the exhaust gases oriented towards a geometric center of the communicating hole.

18. An exhaust system for discharging exhaust gases through an exhaust passageway, emitted from a multi-cylinder combustion engine mounted on a motorcycle, which system comprises:
-
a plurality of header pipes fluid connected with a plurality of engine cylinders of the combustion engine and forming a part of the exhaust passageway; an exhaust collector pipe fluid connected with the plural header pipes which are merged together, a catalytic converter disposed within the exhaust collector pipe; a partition plate dividing the exhaust passageway in the exhaust collector pipe upstream of the catalytic converter into upper and lower introducing passages through which the exhaust gases are introduced into the catalytic converter and having a communicating hole defined therein; and an exhaust gas sensor, positioned at a location close to the communicating hole, for detecting a composition of the exhaust gases; wherein the exhaust gas sensor is positioned in the vicinity of and on an upstream side of the catalytic converter and fitted to the exhaust collector pipe so as to confront the upper introducing passage.
