A fluid injection system for an internal combustion engine such as a spark-ignition or compression-ignition enginein 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.
A system for injecting fluid into a cylinder of an internal combustion engine having an ignition system and an intake manifold, said fluid injecting system comprising first means for introducing air to a supply of said fluid for injecting said fluid into said cylinder at a rate proportional to the flow of said air, and second means in a responsive relation to said ignition system and to said intake manifold for responding to engine speed related signals from said ignition system and to engine load related signals from said intake manifold for introducing air to said first means at a flow that varies in response to engine speed and engine load.
