シリンダにおいて多少とも過熱を生じ勝ちである。Conventionally, this type of device has an engine mounted in the middle of a vehicle body with front and rear heavy wheels, configured as a V-type engine in which a front cylinder and a rear cylinder are arranged in a substantially V-shape. I am not aware of any type in which the cylinder is guided by the traveling wind from the front and is cooled by air, but in this case, the amount of cooling by the traveling wind is somewhat different between the front cylinder and the rear cylinder. There is a difference between both cylinders, and overheating is more or less likely to occur in the rear cylinder.
