PURPOSE:To prevent the drift due to a secular change by storing the fuel augmentation value corresponding to an external load, etc. and rewriting this augmentation value in response to the rotating speed change when an augmenting means is operated. CONSTITUTION:An augmenting means 22 receives a command signal from an external load, etc. during an idle operation and increases the intake air quantity and fuel fed to an engine so as to maintain the idle rotating speed at a preset value. This augmentation value is stored in a rewriting means 25. A rotating speed change detecting means 24 detects the rotating speed change quantity when the augmenting means 22 is operated to correct the aumgmentation value stored in the rewriting means 25 in response to this rotating speed change quantity. Accordingly, the drift due to a sucular change can be prevented. |
