Abstract
In a fuel injection control system which cuts off the fuel supply under certain zero-engine-load conditions, a single asynchronous fuel injection is performed immediately in response to a fuel resumption request. Fuel resumption is ordered when, for example, a throttle valve opens from its idling position or when engine speed drops too low. The single asynchronous fuel injection is performed immediately and with an enhanced fuel quantity to ensure prompt and adequate response to changing engine conditions. Normal, synchronous fuel injection timing is adjusted following fuel resumption to match, or at least not to interfere with, the timing of the asynchronous fuel injection.
