Abstract

PURPOSE:To prevent overheating on the side of a rear cylinder, by a method wherein front and rear cylinders are provided respectively with oil jets faced thereto, and the oil jet quantity of the jet for the rear cylinder is set to be larger than that for the front cylinder by enlarging hole diameter or the like. CONSTITUTION:The front cylinder 6a and the rear cylinder 6b are provided respectively with the oil jets 11a, 11b faced thereto, and are forcibly cooled respectively by the oil jetted from the jets 11a, 11b. The oil jet quantity of the jet 11b for the rear cylinder 6b is set to be larger than that of the jet 11a for the front cylinder 6a by enlarging the hole diameter, thereby increasing the degree of cooling by the oil. Accordingly, it is made possible to prevent overheating of the rear cylinder from occurring due to the difference in cooling capacity of an airflow during running.

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.
