Simonds, E L

A fuel system for an internal combustion engine and comprising a housing having a first chamber of cylindrical cross-sectional configuration with an upper air inlet port open to an air door and a lower outlet port connected to the engine intake manifold, a cylindrical spool rotatably positioned in the first chamber and having opposed openings which align with the inlet and outlet ports when the spool is in a full open position, a second chamber provided in the housing open to the heat of the engine exhaust system and separated from the first chamber by a partition, a fuel heating envelope secured within the second chamber whereby the heat of the exhaust system surrounds the envelope for heating the interior thereof, a fuel jet extending into the fuel envelope for admitting a fuel thereto, a bleed air passageway provided in the housing for directing air from the exterior thereof to the interior of the fuel envelope, a fuel nozzle secured through the wall and having one end open to the interior of the fuel heating envelope and the opposite end open to the interior of the spool for providing a fuel outlet opening in the spool between the inlet and outlet ports, a potentiometer to provide an analog voltage responsive to the position of the spool, a potentiometer to provide an analog voltage responsive to the rate of flow of the air through the housing, a probe to provide an analog signal responsive to the temperature of the fuel, a fluid injector valve in series with the source of fuel and the housing fuel inlet, and a circuit for converting the spool position, air flow, and temperature signals to an analog fuel demand signal and converting such analog fuel demand signal into a pulse dc signal for controlling the fuel injector valve.
