Abstract: [Task] A task is to improve the flexibility for setting a muffler and sufficiently secure the length of a catalyst while making a V-type engine compact. [Solution] A V-type engine (1) includes an engine body (3) including a crankcase (7) configured to rotatably support a crankshaft (11), and a first and second cylinder banks (8, 9) extending from the crankcase (7), an exhaust collecting pipe (31) connected to the first and second cylinder banks (8, 9), a catalyst (32) accommodated in the exhaust collecting pipe (31), and a muffler (33) detachably connected to the exhaust collecting pipe (31), wherein the catalyst (32) extends in a width direction of the engine body (3) from a distal end side of the first cylinder bank (8) to a distal end side of the second cylinder bank (9).

Abstract: [Task] A task is to make a V-type engine compact while suppressing the decrease in the output thereof. [Solution] A V-type engine 1 includes an engine body (3) including a crankcase (7) configured to rotatably support a crankshaft (11), and a pair of cylinder banks (8, 9) extending from the crankcase (7), a pair of exhaust pipes (31, 32) connected to the pair of cylinder banks (8, 9), a catalyst pipe (34) connected to the pair of exhaust pipes (31, 32), and a catalyst (33) accommodated in the catalyst pipe (34), wherein each of the pair of exhaust pipes (31, 32) is connected to the catalyst pipe (34) on an upstream side of the catalyst (33) in an exhaust direction, and the catalyst pipe (34) is arranged adjacently to the pair of cylinder banks (8, 9).

Abstract: A muffler for an engine includes: a muffler body provided with a muffling chamber; a discharge pipe configured to discharge exhaust gas that has passed through the muffling chamber to an external space, wherein a downstream edge of the discharge pipe in an exhaust direction is shaped into a wave that is continuous in a circumferential direction.
