摘要：
An intake control device changes an intake conduit length from a first length to a second length according to whether or not an engine speed has reached a predetermined threshold value. The threshold value is predetermined on the basis of both an engine output torque in the state of the intake conduit length set to the first length and an engine output torque in the state of the intake conduit length set to the second length.
