<p>PURPOSE: To improve intake-charging efficiency while guiding the relatively low temperature air to an intake device by opening a rear end of an air blowing duct connected to a front opening of a fair ring in a side surface of a main pipe in front of an intake port of an intake device. CONSTITUTION: Traveling air is guided from a pair of front openings 13 in right and left of a fair ring 12 through an air blowing duct 15 by each inside surface of both main pipes 3 and a bottom surface of an upper cover member 6, and a sufficient quantity of air is fed to the periphery of an intake port of intake devices 8, 9 in rear of the air blowing duct 15. In the intake devices 8, 9 for covering over a part between an engine 7 provided under and the main pipes 3 and arranged between a lower surface of the upper cover member 6 placed on a top surface of the main pipe 3 in the same surface with the side surface, in spite of the arrangement of a radiator 11 in front of them, relatively low temperature air can be guided. Intake air charging efficiency is thereby improved.</p> |
