All forms of fuel injection are designed to achieve the delivery of a correct fuel/air mix into an internal combustion engine for the most fuel efficient burn. All forms of fuel injection do so by forcing the fuel under pressure through nozzles (injectors) that breaks up or atomizes the fuel into a fine spray. This spray when mixed in the correct ratio with the air drawn into the engine (or forced into the engine by a turbo or supercharger) burns very completely creating maximum power and minimum emissions. Fuel injection not only provides power improvements over the rpm range of an engine, it can also provide better gas mileage.
