Abstract
An engine includes a V-shaped cylinder body, first and second exhaust manifolds inside a V-shaped line, and an exhaust pipe. The exhaust pipe includes a first upstream end portion into which exhaust gases discharged from first cylinders to the first exhaust manifold flow, and a second upstream end portion into which exhaust gases discharged from second cylinders to the second exhaust manifold flow. A spiral wound gasket seals a gap between the first exhaust manifold and the first upstream end portion.
