ELECTRONICALLY CONTROLLED FLUID INJECTION SYSTEM FOR AN INTERNAL COMBUSTION ENGINE ABSTRACT OF THE DISCLOSURE A fluid injection system for an internal combus- tion engine such as a spark-ignition or compression-ignition engine in which an injection nozzle injects a finely divided spray of fluid, such as water or a water solution, into the engine in response to a flow of atomizing air. The nozzle is connected to a fluid supply reservoir and to the outlet line of an air-injection pump connected to the intake manifold of the engine and to an electronic circuit that includes an inductive pick-up coupled to the ignition system of the engine. The pump operates in response to engine speed by virtue of its connection to the ignition system and in response to engine load by virtue of its connection to the intake manifold. As a result, the flow of atomizing air to the nozzle and therefore the rate and magnitude of water injection is responsive to engine speed and engine load.
