Variable length intake control devices and methods for a straddle type vehicle
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.
摘要（中）：

进气控制装置根据发动机转速是否达到预定的阈值，将进气管长度从第一长度改变到第二长度。 基于设定为第一长度的进气管长度的状态下的发动机输出转矩和设定为第二长度的进气管长度的状态的发动机输出转矩两者，预先设定该阈值。
