Abstract
A first fuel storage portion is disposed on the upstream side of a fuel supply device of an engine so as to be contiguous with an air-intake passage of the fuel supply device. A blow-back suppression plate for suppressing blow-back from the air-intake passage is disposed between a filter element and the first fuel storage portion of an air cleaner. A suction-back passage is formed such that fuel accumulated in a fuel accumulation portion in the air cleaner is suctioned back through the suction-back passage into the air-intake passage. The suction-back passage allows communication between the fuel accumulation portion in the air cleaner and a suction-back port formed at the downstream-side end of the first fuel storage portion.

A structure for suctioning back blow-back fuel, the structure comprising:
- a first fuel storage portion disposed on an upstream side of a fuel supply device of an engine and contiguous with an air-intake passage of the fuel supply device;
- a suction-back passage through which fuel accumulated in an air cleaner is suctioned back into the air-intake passage;
- and
- a blow-back suppression plate disposed between a filter element of the air cleaner and the first fuel storage portion and configured to suppress blow-back from the air-intake passage, wherein
- the suction-back passage allows communication between a fuel accumulation portion in the air cleaner and a suction-back port formed in the first fuel storage portion.
