    摘要: The air flow rate and the speed of an internal combustion engine are sensed and translated into pulse trains of variable frequency. During a time interval defined by the rpm related signal, a digital counter receives and counts the air flow rate frequency. Subsequently, the contents of this counter are counted out by a pulse train whose frequency is adjustable depending on other engine conditions such as start-up, warm-up, idling, full-load and the like. The apparatus also includes circuitry for generating a control pulse of minimun length.
