ABSTRACT:
An apparatus including a mixing chamber is installed between the base of a standard carburator and the intake manifold of a gasoline engine. The mixing chamber includes an air inlet port for admitting a controlled amount of outside air into the mixing chamber and a gasoline vapor port for admitting gasoline vaporized externally of the carburator into the mixing chamber, a carburator inlet port for receiving a mixture of air and partially vaporized gasoline from the throat of the carburator, and an outlet port through which a mixture of all the gases is exhausted into the intake manifold. The carburator includes a first throttle valve for controlling the amount of air and partially vaporized gasoline that passes into the mixing chamber. A second throttle valve is disposed to control the amount of mixed gas drawn through the outlet port of the mixing chamber into the intake manifold. A linkage connected to the accelerator cable of the automobile causes the second throttle to be opened in response to initial displacement of the accelerator. As the engine loading conditions increase and the accelerator is depressed further, the second throttle valve opens further and the linkage causes the first throttle valve to partially open, admitting a normal charge of air and partially vaporized gasoline into the mixing chamber along with the air and gasoline vapor admitted through the two ports thereof.
