Image Number 6 for United States Patent #4491114.
A fuel injection means for an internal combustion engine of an automobile is disclosed which comprises a pulse length determination circuit which receives a driving condition signal and develops a signal of a pulse length corresponding to the driving condition, a fuel injection starting signal generator circuit which develops a fuel injection starting signal and a driving signal generator circuit which develops a driving signal of a pulse length corresponding to that of the signal from the pulse length determination circuit. The driving signal thus developed is sent to a fuel injection valve, thereby fuel of a reliably controlled quantity is injected with a reliably controlled timing not only during usual driving condition but also during acceleration.
