  Fuel injection - Wikipedia, the free encyclopedia
The vast majority of fuel injection systems are for gasoline or diesel applications and to a lesser extent for LPG, and in the past, the designs were quite different.
Computer-controlled TBI was inexpensive, and was primarily a transition phase from carburetors to port fuel injection.
Fuel injection systems such as Hilborn were occasionally used on modified American V8 engines in high performance automobiles of the 1960s, in drag racing, oval racing, and road racing.

Fuel injection systems may be single point where the fuel is injected using one nozzle, usually in the throttle housing, or multi point where each cylinder has its own injector in the inlet manifold.
Fuel injection has been used in diesel engines since the mid 1920s, almost from their introduction (due to the higher energy required for diesel to evaporate).
Fuel injection became widespread with the introduction of electronically controlled fuel injection systems in the 1980s and the gradual tightening of emissions and fuel economy laws.

 Water Injection - A technical description
A water injection system works similarly to a fuel injection system with the difference that it injects water instead of fuel.
Water injection is not to be confused with water spraying on the intercooler's surface, water spraying is much less efficient and far less sophisticated.
Usually a water injection system is engaged when the inlet air temperature is exceeding a certain value, typically 40 degrees Celsius, and the engine is on boost.

Water injection decreases the possibility of detonation by lowering the combustion chamber temperatures and increasing the effective "octane" of the fuel.
Is water injection new?: No. Water injection was used during WWII to surpress detonation in fighter aircraft and increase their service ceiling.

 AllRefer.com - fuel injection (Technology: Terms And Concepts) - Encyclopedia
fuel injection, system in an internal-combustion engine that delivers fuel or a fuel-air mixture to the cylinders by means of pressure from a pump.
It was originally used in diesel engines because of diesel fuel's greater viscosity and the need to overcome the high pressure of the compressed air in the cylinders.
Fuel injection is also now used in gasoline engines in place of a carburetor.

 THEPRA Common - Rail Diesel injection system
Other than in systems with directly driven block or individual pumps, pressure generation and fuel injection control are decoupled in the Common-Rail fuel injection system.
The injection pressure is generated independently of the speed and can be freely selected within a broad range.
The injection control by means of quick-action solenoid valves permits multiple injection which leads to a significant reduction of pollutant emissions and noise development.

 Moon's EFI Fuel-Injection System
The beauty of this system is that the throttle-bodies will work on any intake that accepts three-bolt-style Stromberg or Holley carburetors, except, unlike a carbureted system, you can throw on as many throttle-bodies as possible and the motor will still run great without loading up or running rich.
Because unlike old-school systems where more carbs mean more fuel, a properly functioning EFI system determines how much fuel is necessary for the motor at any given time based on engine speed and a variety of other factors then supplies only as much gas as necessary.
While most fuel injection systems on the market today offer some form of stand-alone computer and operating software, Moon's is the only one available that does not require a laptop for fine-tuning.
