Abstract
An intake air control device including a reed valve passage for supplying intake air via reed valves, and a sub intake passage for creating a swirl in the combustion chamber. The intake air control device further comprises a main intake passage for supplying intake air without passing same through the reed valves. A selection unit selects a passage through which the intake air is passed in response to a current engine driving condition, by selecting the sub intake passage when the current engine driving condition is a low engine speed and low engine load driving condition, selecting the reed valve passage when the current engine driving condition is a low engine speed and high engine load driving condition, and selecting the main intake passage when the current engine driving condition is a high engine speed driving condition.
