気マニホールドを有し、各排気マニホールドから
マフラに至る系路長が不等となつているエンジン
の排気装置に於て、短い方の系路長をマフラ容積
を利用して湾曲することにより延長し、両系路長
を同一としたことを特徴とするエンジンの排気装
置。 In the exhaust system of an engine such as a V-type engine, which has exhaust manifolds on both sides of the engine and the path lengths from each exhaust manifold to the muffler are unequal, the shorter path length is used as the muffler. An engine exhaust system characterized in that it is extended by curving using volume, and has the same path length for both systems.
