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).
