ELECTRONICALLY CONTROLLED FLUID INJECTION SYSTEM FOR AN INTERNAL COMBUSTION ENGINE ABSTRACT OF THE DISCLOSURE A fluid injection system for an internal combustion engine such as a spark-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 that is connected to an electronic control circuit which includes an inductive pick-up coupled to the ignition system of the engine and a pressure responsive sensor that is coupled to the intake manifold. The electronic circuit thus operates the pump in response to engine speed by virtue of its con- nection to the ignition system through the inductive pick-up and in response to engine load by virtue of its connection to the intake manifold through the pressure responsive sensor. AS a result, the flow of atomizing air to the nozzle and therefore the rate and magnitude of water injection is res- ponsive to engine speed and engine load.
