Abstract
Electronic-control carburetor adapted to emulsify a metered amount of fuel in synchronism with the induction phases of the cylinders of an internal combustion engine, which comprises a double sonic venturi system providing a low loss of pressure and supplied under the control of an electromagnetic valve in synchronism with the induction phases of the cylinders.
Claims6
An electronically controlled carburetor for supplying fuel to cylinders of an internal combustion engine, said carburetor comprising:
- a float chamber having a single outlet passage,
