クルエンジンの排気管。 In a V-type two-stroke engine that has a first cylinder that faces diagonally forward and downward with respect to the crankcase, and a second cylinder that faces diagonally forward and upward with respect to the crankcase, both cylinders have their exhaust ports facing downward. The exhaust pipe extending from the first cylinder has a loop portion extending half a circle forward and a chamber portion extending rearward from the loop portion, and the exhaust pipe extending from the second cylinder The exhaust pipe has a loop portion formed by extending rearward after passing around the side and lower part of the exhaust pipe, and a chamber portion extending rearward from the loop portion, and the chamber portions of both the exhaust pipes are both parallel to each other below the engine. The exhaust pipe of a V-type 2-stroke engine is characterized by its arrangement.
