Fuel injector cleaning is a service recommended to remove carbon deposits and debris that build up on the fuel injectors in your engine.
Fuel injectors are valves that allow a precise amount of fuel to be sprayed into each of the cylinders in an engine. That fuel, drawn from the tank and pressurized by the fuel pump, makes its way to the fuel injectors that are inserted into the top of the combustion chamber. The injectors respond to signals from the Engine Control Unit (ECU), the computer that controls engine function, to open and close at the right time. There is typically one fuel injector per cylinder.
Injectors can become partially plugged due to a variety of factors including age, dirty fuel, and the combustion process. A thorough fuel injection cleaning can help to remove these deposits on the injectors and restore their proper function.
There are a few different procedures that are often lumped together under the phrase“fuel injector cleaning”. These include anything from pouring a chemical into your gas tank that is purported to clean your injectors to connecting a high-pressure machine to the fuel rails connected to the injectors and flushing them out. The ultrasonic injector cleaning method is considered to be the most effective method of restoring injectors.
