PROBLEM TO BE SOLVED: To reduce the cost of a suction gas heating device with simplification of the piping structure and surely prevent a carburetor from icing through sufficient utilization of the exhaust heat, even at the time of idling, etc. SOLUTION: To heat suction gas with exhaust heat of engine, an air cleaner 10 and a muffler cover 22 linkedly communicate with each other through a hot gas communication pipe 23, and the hot gas inside the muffler cover 22 is sucked into the primary chamber of the air cleaner 10. One end 23a of the communication pipe 23 is put in communication with the upper half of the muffler cover 22, while the other end 23b is coupled directly with the external air intake of the air cleaner 10. |
