<p>PROBLEM TO BE SOLVED: To expedite the gasification of a fuel at a cold starting time, by making a baffle plate maintain a cold discharge air guiding attitude when the sensing temperature of a bimetal is less than a specific value, and switching the baffle plate to a cold discharge air nonguiding attitude when the sensing temperature of the bimetal exceeds the specific value. SOLUTION: A suction pipe 7 is connected at the rear part of a cylinder head 6, and a baffle plate 9 driven by a bimetal 8 is attached to the rear part of a cylinder 3. When the sensing temperature of the bimetal 8 is less than a specific value, the baffle plate 9 maintains a cold discharge air guiding attitude facing the baffle plate 9 to the outlet of an air leading cover 10, so as to guide a cold discharge air 11 from the air leading cover 10 to the suction pipe 7, and when the sensing temperature of the bimetal 8 exceeds the specific value, the baffle plate 9 is switched to a cold discharge air nonguiding attitude not facing to the outlet of the air leading cover 10. Consequently, the gasificiation of the fuel can be expedited at a cold starting time.</p> |
