[Task] A task is to make a V-type engine compact while suppressing the decrease in the output thereof. [Solution] A V-type engineincludes an engine body () including a crankcase () configured to rotatably support a crankshaft (), and a pair of cylinder banks () extending from the crankcase (), a pair of exhaust pipes () connected to the pair of cylinder banks (), a catalyst pipe () connected to the pair of exhaust pipes (), and a catalyst () accommodated in the catalyst pipe (), wherein each of the pair of exhaust pipes () is connected to the catalyst pipe () on an upstream side of the catalyst () in an exhaust direction, and the catalyst pipe () is arranged adjacently to the pair of cylinder banks ().

V-type engine

A V-type engine includes an engine body including a crankcase configured to rotatably support a crankshaft, and a first and second cylinder banks extending from the crankcase, an exhaust collecting pipe connected to the first and second cylinder banks, a catalyst accommodated in the exhaust collecting pipe, and a muffler detachably connected to the exhaust collecting pipe, wherein the catalyst extends in a height direction of the engine body from a base end side of the first cylinder bank to a distal end side of the first cylinder bank.
