A fluid injection system and method for an internal combustion 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 that supplies pressurized air to the exhaust system of the engine. The air-injection pump provides the supply of atomizing air to the nozzle with the pressure of the air and therefore the fluid injection being responsive to both the engine speed and the exhaust gas pressure. The injected fluid advantageously functions as a cooling agent to suppress detonation and provide smoother engine operation and greater fuel efficiency.
A system for injecting fluid into a cylinder of an internal combustion engine having an output shaft and an exhaust system, said system comprising first means for receiving air and pressurizing said air, second means for introducing pressurized air from said first means to a source of said fluid for injecting said fluid into said cylinder, and third means in a responsive relation to said output shaft and said exhaust system for regulating the pressure of said latter pressurized air in response to engine speed and exhaust gas pressure before said pressurized air is introduced to said source of fluid.
In an internal combustion engine having a cylinder, an output shaft, an exhaust system and a pump driven in proportion to the output shaft for pressurizing air for passage to said exhaust system, the improvement comprising means for introducing pressurized air from said pump to a source of fluid for injecting said fluid into said cylinder, and means in a responsive relation to said output shaft and said exhaust system for regulating the pressure of said latter pressurized air in response to engine speed and exhaust gas pressure before said pressurized air is introduced to said source of fluid.
A method for improving the efficiency of an internal combustion engine having a combustion chamber, an output shaft, an exhaust system and a air pressurizer driven by said output shaft for pressurizing air for passage to said exhaust system;
