Claims

[Scope of claim for utility model registration] 2 branches that branch toward the downstream side from the common exhaust passage
In an exhaust system for a vertical engine having two branch exhaust passages, the common exhaust passage extends rearward along the outer periphery of the oil pan of the transmission, and the rear end of the oil pan connects to the extension housing at the rear of the transmission. The common exhaust passage is branched into a first branch exhaust passage and a second branch exhaust passage at a lower position, and the first branch exhaust passage is arranged to extend almost rearward from the branching part, while the second branch exhaust passage The passage is arranged so as to extend from the branch part to a predetermined position along the rear end surface of the oil pan, and then to extend almost rearward, and the passage is arranged so as to extend from the branch part to a predetermined position along the rear end surface of the oil pan, and the passage is arranged so as to extend almost rearward from the branch part, and the passage is arranged so as to extend from the branch part to a predetermined position along the rear end surface of the oil pan, and then to extend substantially rearward. An exhaust system for a vertical engine, characterized in that catalytic converters are connected to each extension housing.
