Abstract
A apparatus for controlling the number of the rotation of an internal combustion engine, which is capable of feeding air-suction quantity back to the objective value and provided with memory storing and retaining the feedback value when the feedback operation is stopped. When faster adjustment is needed at the moment of resuming the feedback operation or performance characteristic of the air-suction control system largely varies during service period, the apparatus securely retains the feed-back value and applies it as the initial value to allow the engine to securely reactivate satisfactory startup operation.
