ABSTRACT:
A fluid bleed device for controlling the amount of natural gas supplied to the carburetor of a turbocharged carbureted natural gas engine provides a regulated output fluid pressure to the setpoint of the natural gas supply regulator feeding the carburetor. This regulated output fluid pressure is related to the magnitude of two input variables, the turbocharger output pressure and an electric signal from an exhaust gas sensor reflecting the engine exhaust gas composition. Turbocharger air input to the bleed device passes through two restrictive orifices and a nozzle in series. The nozzle is variably occluded by a movable member controlled by an electromagnet powered by the electric signal. The regulated output fluid pressure is taken from the junction between the two restrictive orifices to supply a pressure to the gas supply regulator that is related to both turbocharger outlet pressure and the exhaust gas composition for enhanced engine efficiency.
