Fuel Injectors

A fuel injector is a device for atomizing and injecting fuel into an internal combustion engine. The injector atomizes the fuel and forces it directly into the combustion chamber at the precise point in the combustion cycle. Newer injectors can also meter the amount of fuel as dictated and controlled by the electronic control module (ECM). Gasoline fuel injectors now act as an alternative to a carburetor, in which an air-fuel mixture is drawn in by the vacuum created by the downward stroke of the piston.
