Abstract
The intake device for an engine includes a carburetor section and an air cleaner section. The carburetor section includes a body having an intake passage which has an opening communicating with the air cleaner section and a choke valve being a butterfly valve having a plate-like valve body. The air cleaner section includes an air filter, an air-flow chamber provided between the air filter and the intake passage, and a reverse-flow restriction surface provided within the air-flow chamber. The air cleaner section further includes a plate-like partition extending from a location near an air-cleaner side periphery of the valve body of the choke valve in the full-open position to a location near the reverse-flow restriction surface so as to continue the periphery.
