Abstract
Abstract A fuel injector is provided in an internal combustion engine whereby a mixture of fuel and air can be introduced into the intake manifold of the engine. The device includes a plunger or piston-like member that serves to selectively expose portions of slots through which fuel passes so that the fuel and air can be introduced into the intake manifold with maximum efficiency whereby increased mileage and the like can be accomplished.
