Fuel Injector

The fuel injector is a pivotal component to the vehicle as it is responsible for spraying fuel into the engine's cylinder. It is driven by the engine control unit, and this system looks over the injectors to see if they release sufficient fuel to generate the air-fuel mixture for the engine.

Fuel injector principles

The fuel injector is important to the vehicle since it controls the amount of fuel that goes into the combustion chamber, while also getting the timing perfect. Because without the right amount of fuel and synchronization it won't create the spark you need. This causes a misfire which leads to problems with the fuel-air mix in the combustion chamber.

Modern vehicles are now being made with a decent amount of power, able to keep up the fuel economy and emissions that are released from the exhaust while being within the law. All this is only possible with the fuel injector and a regulator on the fuel pump which tolerates less amount of fuel lines.

Common issues with a bad fuel injector

A bad fuel injector can cause rough idle, engine misfires, poor engine performance and the fuel economy of the vehicle will go down drastically.
