PURPOSE:To raise the responsibility and reliability of controlling the number of idle revolutions by providing a detecting means for detecting the operation initiation of engine load, a memory means for storing a feedback correction value, and a controlled value correcting means. CONSTITUTION:When engine load such as a cooler, etc., begins to operate, a load correction value is added to a feedback control value, allowing the amount of intake air to be controlled. Simultaneously, a memory means stores a signal from an engine load detecting means as a feedback correction value. Further, this feedback correction value is taken out by a controlled value correcting means and given to a feedback control means. Just after engine load is stopped, a relatively large feedback correction value before the engine load is operated is used. Hereby, the responsibility and reliability of controlling the number of idle rotation are raised. |
