Abstract

PURPOSE:To save the fuel expenses and to reduce a noise by carrying out the feedback correction to approach the variation of operational condition which presents the stable operation of the internal combustion engine to the specific maximum value when the internal combustion engine is in a specific low load constant operation condition. CONSTITUTION:A device A sets a standard control value of an object to control to a control target in a specific low load constant operation condition of the internal combustion engine. And a device B detects the specific low load constant operation condition, while a device C detects the operational condition variation which presents the stable operation property of the internal combustion engine. On the other hand, a device D sets the feedback correction value to correct the standard control value to approach the operational condition variation to the specific maximum tolerance when the specific low load constant operation condition has been detected. And a device E operates a control value from the feedback correction value and the standard control value, and a device F controls the internal combustion engine depending on the control value.
