Abstract
A fluid injector for internal combustion engines in which the fluid flow to the engine is indicated in the driver's compartment and in which a mixing chamber in the compartment communicates with a primary vacuum line of the engine and with a fluid reservoir. A valve is disposed between the reservoir and the chamber to prevent the flow of fluid from the reservoir when the engine is not running. A needle valve is disposed in a fluid inlet port for adjusting the volume of fluid entering the chamber. An adjustable air inlet port is disposed in the chamber, and a vacuum gauge is provided for monitoring the vacuum in the chamber. The vacuum from the primary vacuum line draws fluid into the chamber from the reservoir, where the fluid mixes with air and the mixture is drawn to the engine carburetor.
