ABSTRACT:
A fluidic implementation of a constant mass airfuel ratio fuel-injection system which may be utilized, for example, in an internal combustion engine. The system includes a fluidic mass air flow sensor that produces a pressure oscillation in direct proportion to the mass air flow to the engine. The frequency of this oscillation is utilized to control a fuel flow metering device which delivers a fixed amount of fuel per oscillation cycle. In one preferred embodiment, the metering device may comprise a fixed displacement piston pump. In an alternative embodiment, the metering device comprises a constant pulse-width fluidic amplifier.
