Abstract:
1. A water injection engine comprising: a) an internal combustion engine having at least one combustion chamber, having at least one reciprocating piston, having a cylinder head, having at least one intake port and having at least one exhaust port with at least one exhaust conduit; b) an air intake path, having an air filtering system and an air mixing system, directing a charge of air into said air intake port; c) an exhaust path, having said exhaust port connected to said exhaust conduit for the expulsion of exhaust gases from said engine; d) a water injection system for containing an ultra-pure water supply in fluid connection with vessels, valves, purification means, pressurizing means, control means and vaporization means in fluid connection with said air intake path of said engine; e) a holding tank for receiving said ultra-pure water supply in fluid connection with a solenoid valve for the purpose of open/closed control of said holding tank, a liquid level sensor for the purpose of alerting operator to maintain supply of said ultra-pure water supply and a pressurizing means being electrically controlled for the purpose of variable pressure and volumetric control of said ultra-pure water supply; f) at least one ultrasonic vaporization unit in fluid connection with said holding tank to create an aqueous vapor to be injected into said air intake path; g) a housing containing said ultrasonic vaporization unit connected to said air intake port for mixing said vapor with said intake air charge of said internal combustion engine; h) at least one electronic control unit for the purpose of monitoring and controlling functions of said water injection engine which pertain to the operation of said ultrasonic vaporization unit, including at least the monitoring of exhaust gas temperature, intake manifold pressure, accelerator position, liquid level of said ultra-pure water supply, pressure of said holding tank and which unit also controls said ultrasonic vaporization unit including on/off control and variable pressure control and being electrically connected to a DC power source; i) at least one catalytic fuel-conditioning unit in fluid connection with said fuel supply of said engine and also in fluid connection with said combustion system of said engine and containing base metal catalysts and metal alloyed catalysts for restructuring said fuel.
