アイドル回転数制御装置。 An engine equipped with a post-start air supply means that supplies post-start air to a combustion chamber after the engine starts, and a post-start air reduction means that gradually reduces the amount of post-start air supplied to 0 at a predetermined reduction rate. The idle speed control device includes an engine speed detection means for detecting the engine speed, and a post-start air reducing means that detects the engine speed when the engine speed decreases below the target speed while the post-start air is being supplied. 1. An engine idle speed control device comprising: post-start air reduction suppressing means for suppressing air reduction after starting.
