Claims

[Scope of utility model registration request]

An idle speed control valve installed in the auxiliary air passage that bypasses the throttle valve of the engine intake system, an engine speed detection means for detecting the engine speed, and a rewritable target idle speed memory that stores the target idle speed. and an idle rotation speed for controlling the opening degree of the idle rotation speed control valve so that the engine rotation speed detected by the engine rotation speed detection means becomes the target idle rotation speed stored in the target idle rotation speed storage means. a control means; a target idle rotation speed correction means for correcting and rewriting the target idle rotation speed in the target idle rotation speed storage means according to an adjustment signal; An idler for an internal combustion engine, comprising: independently provided adjustment signal output means capable of outputting to a rotation speed correction means, and configured such that an output line for an adjustment signal to the target idle rotation speed correction means can be freely intermittent. Rotation speed control device.
