ABSTRACT:
The thermal and vacuum tracking carburetor Jet is a variable size jet. The opening size is continuously controlled by a thermal spring transducer measuring the temperature of the exhaust gasses, and by a vacuum diaphragm transducer measuring the vacuum within the intake manifold of the engine. When exhaust gasses become too hot indicating too lean a fuel mixture the thermal spring expands opening the jet; if the gasses are too cool the spring contracts and via mechanical linkage, the jet closes. When engine vacuum falls indicating more of a load is placed on the engine the vacuum diaphragm transducer opens the jet providing a richer mixture; when vacuum rises indicating a lessened load or deceleration the jet closes producing a leaner mixture.
