ABSTRACT:
A fluidic fuel charge injection device for an internal combustion engine includes an impacting stream device having a deflection control nozzle and a control chamber enclosing a main stream nozzle. The device is mounted in the engine manifold to introduce the fuel charge. The device operates at high pressure levels and the control signals are amplified to the necessary power level. An engine revolutional signal is a modulated pulse width signal formed by triggering of high power level fluidic amplifying devices which include a plurality impacting stream fluidic operating as NOR logic elements. An amplifying section includes a transverse impact modulator follower (TIMF) connected to the logic output to produce a pair of interrelated fluid signals proportional to the engine RPM. The pair of signals are applied to the control chambers or through a fluidic coupling stage to a control chamber or to the main stream nozzle for controlling the air-fuel mixture and the introduction of the charge into the manifold.
