the delivery, under pressure, of a metered amount of fuel, as a fine spray, into the intake airflow or combustion chambers of an internal combustion engine
(Otomotiv) The modern replacement to a carburetor that uses an electronic fuel management system to deliver a specific amount of fuel to each combustion chamber in response to changes in engine speed and driving conditions
method of streaming fuel to the motor which guarantees better operation by the motor
Fuel injection is a system in the engines of some vehicles which forces fuel directly into the part of the engine where it is burned. Any of several methods or mechanical systems by which a fuel is reduced to a fine spray and injected directly into the cylinders of an internal-combustion engine. a method of putting liquid fuel directly into an engine, which allows a car to accelerate more quickly. In an internal-combustion engine, introduction of fuel into the cylinders by a pump rather than by the suction created by the movement of the pistons (see piston and cylinder). On diesel engines, which lack spark plugs, the heat created by compressing air in the cylinders ignites the fuel, which has been pumped in as a spray. In engines with spark ignition, fuel-injection pumps are often used instead of conventional carburetors. Fuel injection distributes the fuel more evenly to the cylinders than does a carburetor; more power can be developed and undesirable emissions are reduced. In engines with continuous combustion, such as gas turbines and liquid-fueled rockets, which have no pistons to create suction, fuel-injection systems are necessary
mechanical system to inject atomized fuel directly into the cylinders of an internal-combustion engine; avoids the need for a carburetor
