Abstract:
1. An internal combustion engine system having water injected into the engine for reducing NOx and CO gases, the internal combustion engine system comprising: a. an engine casing having an interior cylinder having a cylindrical wall portion and a piston having an upper surface and a perimeter annular edge portion, the piston operatively configured to be repositioned within the interior cylinder in an oscillating manner and further being connected to a crankshaft, b. an ignition member having anode and cathode portions optimally configured to provide an ignition spark within the interior cylinder, c. a fuel air input valve and an exhaust valve configured to insert a fuel air mixture into the interior cylinder and remove combusted gas respectively, the piston, interior cylinder and fuel air input and exhaust valves having relative positions so the piston has a downward fuel air intake stroke, an outward fuel air compression stroke, a downward power stroke, and an upward exhaust stroke, d. a nozzle member having a main body and a nozzle tip region in communication with the interior chamber, the nozzle member comprising an actuator to alternatively allow communication of the nozzle tip region to a high-pressure water source and to discontinue communication of the nozzle tip region to the high-pressure water source, the nozzle further having a spray cone adjustment system where the cross-sectional open area of the nozzle member at the nozzle tip region is repositioned up from a narrower orientation to disburse a narrower apical angle of a water disbursement cone to a wider orientation to disburse a wider apical angle of a water disbursement cone, e. a high-pressure pump in communication with a high-pressure source to increase the pressure thereof prior to the transfer of water to the nozzle member for dispersion within the interior cylinder, f. a logic controller having a pressure sensor of the high-pressure source where the logic controller is configured to operate the high-pressure pump to increase the pressure of the high-pressure source, the logic controller being operatively configured to control the actuator of the nozzle member to allow communication of the high-pressure source and the interior chamber, the logic controller being configured to inject a spray cone mist of water during the upward fuel air compression stroke at a first apical cone angle and inject a spray cone mist of water at the transition from the upward fuel air compression stroke to the downward power stroke at a second apical column angle which is greater than the first apical cone angle where the first and second apical cone angles with respect to the location of the piston are such that the spray cone mast does not directly contact the cylindrical wall portion of the interior chamber.
