Abstract: An HC adsorbing sheet inside an air cleaner is disposed such that a large amount of activated carbon is contained on the side of an engine and that a small amount of activated carbon is contained on the other side of the engine. Thus, the HC adsorbing sheet can efficiently adsorb evaporative fuel. That is, by changing the amount of activated carbon contained in accordance with differences in concentration of evaporative fuel, it becomes possible to prevent the pressure loss in an intake system from increasing. On the other hand, one end of a second intake pipe extends to a region where the amount of activated carbon contained in the HC adsorbing sheet is large, whereby it becomes possible to concentratively supply activated carbon with intake air in the region where the large amount of activated carbon is contained. Therefore, the efficiency in purging evaporative fuel can be prevented from declining.
