摘要:
An engine includes a cylinder block including a plurality of cylinders disposed along a V-shaped line, a pair of exhaust manifolds disposed inside the V-shaped line, and an exhaust pipe disposed inside the V-shaped line. Each of the pair of exhaust manifolds includes a first passage that includes a plurality of inflow ports into which exhaust gases from the cylinders flow, a collecting portion at which exhaust gases are collected, and an exhaust port from which exhaust gases are discharged. The exhaust pipe includes a connection passage that includes a pair of intermediate inflow ports that are connected to the exhaust ports, at least one intermediate exhaust port from which exhaust gases are discharged. The connection passage is arranged to connect the pair of intermediate inflow ports and the at least one intermediate exhaust port.
