Description
What Is the Function of a Fuel Injector?
The function of a fuel injector is to spray atomized fuel into the
combustion chamber of an internal combustion engine. Fuel injection
became the primary fuel delivery system in automobiles starting in
the mid-1980s. The spray from a fuel injector can be continuous or
intermittent.
Definition of a Fuel Injector
The fuel injector is a small nozzle into which liquid fuel is
injected at high pressure. It works like a spray nozzle of a
pressure washer. The placement of the injector can be in a
different part of the engine depending upon the type of fuel
injection system is being used. High pressure from the fuel pump
feeds the fuel to the fuel injector.
Precise Fuel Metering
The fuel injector meters the fuel more precisely than a carburetor.
Therefore, no fuel is wasted. The result of such precise metering
is increased power, lower emissions and lower fuel consumption. The
right amount of fuel is squirted into the combustion chamber or
throttle body. Excess fuel goes back to the fuel tank. A metering
unit delivers fuel to the fuel injectors, according to the Reader's
Digest Complete Car Care Manual. General Motors said in 1982 that
the fuel injection system delivers the proper amount of fuel after
the electronic control module reads manifold vacuum, engine
temperature and engine rotations per minute.
Maximum Airflow
The fuel injector also frees the intake system for maximum airflow.
The accelerator pedal is not necessarily a gas pedal. It controls
the position of the throttle plate. The airflow is increased or
decreased depending upon the accelerator's position. The airflow
and fuel mixture is optimized by the engine control unit hundreds
of times per second. The airflow and fuel mixture determine the
length of time the fuel injector sprays fuel into the port,
according to Auto Media.
