<p>PURPOSE:To reduce a noise of intake air and improve dustproof performance, by spirally providing separator walls, dividing cooling air into parts for cooling each cylinder, in a fan housing and arranging an air intake port of an air cleaner in the fan housing. CONSTITUTION:A device, introducing suction air into a housing 6 from a cooling air intake port 8 to be pressurized by a centrifugal fan 5 and divided into parts for both cylinders 1, 2 by both separator walls 9, 10, guides the air to be turned by an internal peripheral surface of the separator wall 9, 10. Air, being guided by the first separator wall 9, reaches an upper part of the first cylinder 1, and a part of the air, being inducted into an air chamber 16 through an air passage 18, goes into an air cleaner 11 from an air intake port 12.</p> |
