Electronic fuel injector control for rotary vacuum fuel conversion device

摘要

An electronic fuel injector control is provided for selectively activating fuel injectors for introducing macroscopic liquid fuel droplets into the vacuum chamber of a device for converting fuel into microscopic fuel droplets and fuel vapor. The control has a rotatably mounted rotor shaft, connectable to the rotor in the vacuum chamber and fuel conversion signal device to provide first periodic signal pulses responsive to the angular rotational position of the rotor shaft. Engine sensor electronics is responsive to input signals from engine sensors indicative of engine condition and is further responsive to an output signal pulse from the fuel conversion signal device each time the vane sweeps past the fuel injector. A sensor is provided which is responsive to the desired angular position of the engine crankshaft to provide second periodic signal pulses. An electric motor connected to the rotor shaft, when running, provides a blocking signal to the engine sensor electronics to block the signal pulses from the fuel conversion signal device so that the fuel injectors are activated only in response to the crankshaft pulses.
