Claims

[Claims for Utility Model Registration] In an engine in which exhaust passages of a plurality of cylinders are assembled to form two systems of collective exhaust passages, a communication passage is provided that communicates the two systems of collective exhaust passages, and the communication passage is An engine characterized in that a large-diameter hole having a diameter larger than the diameter of the communication path is provided so as to intersect approximately in the middle of the communication path, and a detection part of an exhaust gas concentration sensor is inserted into the large-diameter hole with a slight clearance. exhaust system.
