Abstract:
1. An electronic pressure regulator for use with a gaseous fuel internal combustion engine having an engine control module, a fuel line source having an outlet in communication with the engine, fuel line including a controllable valve for regulating the gaseous fuel pressure at the outlet, and a venturi carburetor in communication with the fuel line outlet and the engine, comprising: a first pressure sensor providing a first signal corresponding to gaseous fuel pressure at the inlet of the carburetor; a second pressure sensor providing a second signal corresponding to air inlet pressure at the outlet of the carburetor; a delta pressure sensor sensing the difference between the first signal and the second signal; wherein said delta pressure sensor receives a command signal from the engine control module and determines the required new pressure and provides a third signal to the a voice coil actuator; wherein the voice coil actuator responds to said third signal and provides a direct mechanical input to a mechanical pressure regulator; and wherein said mechanical pressure regulator provides a signal to the venturi carburetor to adjust the amount of fuel being provided to the engine.
