Device, systems and methods for introducing water into the combustion chamber of an internal combustion engine, incorporating an injector and a heater, are shown and described. The injector is configured to inject water at a pulse rate and frequency controlled by various engine performance readings, and the heater configured to convert the water into steam on demand, and to route the steam into the air stream flowing toward the combustion cylinder. In certain embodiments, the heater is positioned to provide steam to the cylinder before the temperature of the steam changes significantly. In other embodiments, the heater is configured to convert to steam a flow of water equal to or less than the amount of fuel burned by the engine during the same time period.

What is claimed is: 1. A system for introducing water into the fuel-air mixture of an internal combustion engine, the engine having a combustion chamber and an intake port in communication with the combustion chamber, the system comprising: a heater adapted to convert the water to steam, without significant delay, as the water flows through the heater, the heater being in close communication with the intake port of the engine such that the steam leaving the heater enters the intake port before a temperature of the steam changes significantly; a water supply adapted to supply the water to the heater; and an injector configured to controllably introduce the water to the heater, at least in part, in response to a timing signal generated by the engine. 2. The system of claim 1 wherein the heater is operated by electricity. 3. The system of claim 1 wherein the heater comprises at least one glow plug. 4. The system of claim 1 wherein the heater comprises a ceramic heater. 5. The system of claim 1 wherein the heater operates using microwaves. 6. The system of claim 1 wherein the heater operates by burning fuel. 7. The system of claim 1 wherein the heater is configured to dispense the steam directly into the intake port. 8. The system of claim 1 wherein the water supply includes a tank. 9. The system of claim 1 wherein the injector is located upstream of the heater. 10. The system of claim 1 wherein the injector includes a solenoid valve. 11. The system of claim 1 wherein the injector is controlled, at least in part, in response to a signal generated by the engine. 12. The system of claim 1 wherein the injector is controlled, at least in part, in response to a temperature signal generated by the engine. 13. The system of claim 1 wherein the injector is controlled, at least in part, in response to an emission component signal generated by the engine. 14. The system of claim 1 wherein the heater and the injector are independent components. 15. A system for introducing water into the fuel-air mixture of an internal combustion engine, the engine having a combustion chamber and an intake port in communication with the combustion chamber, the system comprising: a heater adapted to convert the water to steam, without significant delay, as the water flows through the heater, the heater being in close communication with the intake port of the engine such that the steam leaving the heater enters the intake port before a temperature of the steam changes significantly; a water supply adapted to supply the water to the heater; and an injector configured to controllably introduce the water to the heater; wherein the heater and the injector are coupled to a single housing. 16. The system of claim 1 wherein the heater is mounted to the engine. 17. The system of claim 1 wherein the heater is configured to be installed in a water line. 18. The system of claim 1 comprising a plurality of heaters and a plurality of injectors. 19. The system of claim 1 comprising a plurality of heaters and a plurality of injectors, the number of heaters and injectors corresponding to the number of cylinders. 20. A water heater for use in combination with an internal combustion engine adapted to convert a supply of water to steam, without significant delay, as the water flows through the heater, the heater being configured to be coupled to an intake port of the internal combustion engine such that the steam leaving the heater enters the intake port before a temperature of the steam changes significantly, and wherein the heater is configured to be mounted directly on the intake port. 21. The heater of claim 20 wherein the heater is configured to be mounted on the engine. 22. The heater of claim 20 wherein the heater is configured to be installed in a water line. 23. The heater of claim 20, further comprising an injector configured to control a supply of water to the heater. 24. The heater of claim 20, further comprising an injector coupled to the heater and configured to control a supply of water to the heater. 25. A water heater for use in combination with an internal combustion engine adapted to convert a supply of water to steam, without significant delay, as the water flows through the heater, the heater being configured to be coupled to an intake port of the internal combustion engine such that the steam leaving the heater enters the intake port before a temperature of the steam changes significantly, further comprising an injector mounted directly on the heater and configured to control a supply of water to the heater. 26. A method for introducing water into the fuel-air mixture of an internal combustion engine, the method comprising: providing a source of water; routing the water toward a location on the engine where at least air is flowing toward a combustion cylinder; routing the water to a heater configured to convert the water to steam as the water passes through the heater; and injecting the water into the heater at a controlled rate, wherein injecting the water comprises injecting small quantities of water in response to a signal from the engine. 27. The method of claim 26 wherein providing a source of water comprises mounting a water tank to a vehicle. 28. The method of claim 26 wherein routing the water to the heater comprises routing the water to a pump and pumping the water toward the heater. 29. The method of claim 26 wherein routing the water to the heater comprises routing the water to an injector in communication with the heater. 30. The method of claim 26 wherein routing the water toward a location on the engine comprises routing the water toward an air intake fitting for the engine. 31. The method of claim 26 wherein routing the water toward a location on the engine comprises routing the water toward a throttle component for the engine. 32. The method of claim 26 wherein routing the water toward a location on the engine comprises routing the water toward an intake port for the engine. 33. The method of claim 26 wherein routing the water toward a location on the engine comprises routing the water toward a combustion cylinder for the engine. 34. The method of claim 26 wherein injecting the water comprises repeatedly injecting small amounts of water toward the heater. 35. The method of claim 26 wherein injecting the water comprises injecting water directly into the heater. 36. The method of claim 26 wherein injecting the water comprises injecting small quantities of water in response to a signal from the engine. 37. The method of claim 26 wherein injecting the water comprises injecting a stream of water into a single heater.
