What Are Fuel Injectors?

In a few moments, we’re going to work to answer the question, “Does fuel injector cleaner work?”, for you. But before we do that, it’s important for you to know exactly what fuel injectors are so that you understand why it’s so essential for you to keep them clean. If you don’t know the importance of fuel injectors, you aren’t going to see how serious of a problem that dirty fuel injectors can be for you and your car.


Fuel injectors are small parts within your fuel injection system that are designed to take fuel and spray it into the intake manifold in your engine at the right angle. In doing so, it allows the fuel that is introduced into your intake manifold to mix together with the right amount of air. The air-fuel mixture that is cremated is then compressed within the combustion chamber in your engine so that it’s able to create the chemical reaction that is necessary to power your engine.


If your fuel injectors are dirty, it can make it impossible for them to provide your engine with the right amount of fuel. It can throw the entire air-fuel mixture off and result in your engine getting either too much fuel or not enough of it. This can eventually result in major problems within your engine if you’re not careful. It’s why you need to ask questions like, “Does fuel injector cleaner work?”, and make it your mission to keep your fuel injectors clean.

How Often Do Fuel Injectors Need to Be Cleaned?
