What is a fuel injector?
The fuel injector is a crucial component of the fuel system that delivers fuel to the engine’s combustion chamber. It’s a sophisticated electric solenoid that quickly opens and closes to precisely control the fuel flow to the engine. Fuel injectors have replaced carburettor systems because they offer better control over fuel delivery, which can improve engine performance, efficiency and emissions.
Maintaining fuel injectors properly is essential to ensure optimal engine performance and fuel economy. Failure to do so can result in reduced power, rough idle and increased emissions.
What does a fuel injector do?
A fuel injector essentially functions as a small nozzle that sprays fuel into the combustion chamber in precise amounts and at the correct time. This is achieved by a series of electrically controlled pulses that open and close the injector rapidly, allowing fuel to be sprayed in a fine mist. The amount of fuel sprayed is carefully regulated by the vehicle’s engine control unit (ECU), which considers various factors such as engine speed, load and temperature to ensure optimal fuel delivery for efficient combustion. 
When do I need to change my Injectors?
Several signs may indicate a older fuel injector needing replacement. One of the most common is a decrease in fuel efficiency, as the engine may be using more fuel than usual due to an improperly functioning injector. Additionally, you may notice a lack of power or acceleration when pressing the gas pedal, or your engine may idle roughly or stall.
Another reason to change your injectors is to handle power upgrades. Power adders such as Nitrous, Turbo or Supercharger systems all provide more oxygen to the combustion chamber, in turn requiring more fuel than standard.
