Document Type and Number:
Japanese Patent JPS6014184
Kind Code:
B2
Abstract:
To control at least one solenoid operated fuel injection valve in dependence upon the rate of air flow, and particularly to avoid interference with stray signals generated in the electrical system associated with an internal combustion engine, an air flow meter is arranged in the induction pipe of the engine which has an output providing signals in digital form, for example by controlling the frequency of an osciallator which is then converted into digital signals by a frequency/digital converter. The digital signals are applied to a computing circuit which includes a digital differential analyzer and an interpolator, or function generator which is connected therein and so set that it simulates the operating characteristics of the internal combustion engine to modify the digital signal and provide an output which can be converted by a frequency/time converter to a timing signal to control the solenoid of the fuel injection valve and open the fuel injection valve for a predetermined period of time, depending on rate of air flow, or other engine parameters, and as adjusted for the operating characteristics of the engine over its operating range.
