DEVICE FOR CONTROLLING INTERNAL COMBUSTION ENGINE

摘要

In the appts. for controlling an internal combustion engine having a fuel injection control system, the detected number of revolutions is so modified that it becomes higher than an actual number of revolutions when a changing rate of the number of revolutions is larger than a predetermined value and the actual number of revolutions tends upward. The number of revolutions lower than the actual one when the changing rate is larger than the actual one when the changing rate is larger than the predetermined value, and the actual number of revolutions tends downward. The quantity of fuel to be injected is calculated on the basis of the modified number of revolutions. The deceleration shock or surging occurring during the low speed running of an automobile can be effectively diminished without any deterioration of the exhaust gas.
