PURPOSE:To enhance, the stability of rotation upon running of an engine at a slow speed, by providing a setting means for determining the characteristic curve of idling control, a means for computing the fuel injection amount to control the idling operation and a means for providing a necessary fuel injection amount. CONSTITUTION:An idle characteristic computing circuit 12 and a first computing circuit 13 conduct, in combination, a proportional control for fast idle operation in accordance with the data D2 of fuel injection amounts. A second computing circuit 14 computes the amount of fuel injection for partial load opration, and delivers the second data D3 of fuel injection amounts. A third computing circuit 15 issues the third data D4 of fuel injection amounts which indicate a maximum fuel injection amount. Further, there is provided a compensating amount computing circuit 16 in order to sustain a lowest idling speed. With this arrangement it is possible to enhance the stability of rotation upon slow speed operation. |
