PROBLEM TO BE SOLVED: To provide an exhaust structure of a multicylinder engine that prevents heat damage to an ancillary member of an exhaust sensor, and improves fuel economy by stabilizing measurement of the exhaust sensor.SOLUTION: A catalyst 10 is installed via an exhaust pipe 8 in the vicinity of an outlet 6a of an aggregation part 6 of an exhaust manifold 3 formed in a cylinder head 2. The exhaust sensor 12 is arranged on the upstream side of the catalyst 10 and closer to one side in the extending direction of a crankshaft 16 indicated by a dashed line. The center line 6b of the outlet 6a of the aggregation part 6 is offset to the same side where the exhaust sensor 12 is arranged, with respect to the center line 3a of the exhaust manifold 3. |
