<p>PURPOSE:To prevent the undershoot of an engine effectively even if fuel cut is continued to a rotating number near the same of idling by a method wherein the power generation of a charging generator is stopped or limited for a given time until the rotation of the engine is stabilized after fuel supply is reopened to reduce the load of the engine. CONSTITUTION:When the deceleration of a vehicle is started and the rotating number of an engine arrives at a predetermined value near the rotating number of idling, fuel injection is reopened and a fuel supply reopening signal 3a is outputted. Accordingly, the operation of the timer 21 is started and an output, becoming 'H' level for a given period of time, is outputted. During this period, the power generation of a charging generator is stopped. According to this method, the load of the engine is reduced and the rotation of the engine is stabilized at the rotating number of idling during a given period of time without generating any undershoot of the rotation of the engine by the re-injection of the fuel.</p> |
