ABSTRACT:
A backup system for an electronic fuel injection control system as for an internal combustion engine, which has the ability, when the electronic fuel injection control device fails to function normally or when there arises the possibility of inducing this failure, to control the duration of the opening of the injector's valve and consequently the volume of fuel to be injected to the extent of permitting the start of the internal combustion engine without recourse to the signal from the sensor system now out of order or the operation of the electronic control device, and thus is capable of controlling the internal combustion engine without obstructing the operation of starting, warming-up and cruising in the case of the aforementioned trouble.
