How a Mechanical Fuel Injector Operates
When a mechanical fuel injector operates properly, an engine can perform smoothly and powerfully. Problems with stalling and misfiring are likely a possibility when fuel injectors dont operate correctly. Several factors decide how a fuel injector operates.
Injector Operation
Mechanical fuel injectors are responsible for inserting pressurized fuel into a vehicles engine. The injectors have small nozzles through which the fuel is sprayed. Injectors are known to perform better than carburetors because of their ability to handle different types of fuel, and operate at high temperatures.
PCM Operation
The Powertrain Control Module is a computer within a fuel injection system. Fuel injectors will open only after receiving instructions from the PCM. An injector-driver allows the PCM to communicate directly with the fuel injectors.
Sensor Operation
A fuel injector system utilizes several sensors in order to operate properly; one of these is an airflow sensor. Airflow sensors can read the amount of air thats entering your vehicles engine. A throttle-position sensor is another type of sensor and can be used to determine engine and vehicle speed.
