PURPOSE:To make the heated air by engine so as not to be drawn in from the suction port of an air cleaner in time of running at low speed as well as to keep a charging efficiency in the engine satisfactory at all times, by installing two heat insulating diaphragms between the engine and the suction port with these diaphragms close to the suction port. CONSTITUTION:On both side walls of an air cleaner 8, suction pipes 111 and 112 made of a synthetic resin extending over the rearward of a car body are installed in the base end side, and a suction port 12 of each of these suction pipes 111 and 112 is opened toward the rearward at both sides of a suction box 10. On the rear surface of both suction pipes 111 and 112, heat insulating diaphragms 131 and 132 made of a synthetic resin are solidly formed up, and a duct space S1 isolated from an engine 4, is partitioned by each of these diaphragms 131 and 132, each side of the suction box 10 and the rear surface and each inside surface of a fuel tank 7. |
