  • The Importance of Clean Fuel Injectors


    Automotive fuel injection was a big technological step forward, resulting in reduced environmental pollution as well as improved engine performance and fuel mileage. A major part of their superiority lies in improved monitoring and precise delivery of the needed fuel to be mixed with the available air for proper combustion. But fuel injectors are subject to wear, contamination, and component failure to the same degree as the parts they replaced.


    The injector's nozzle atomizes the fuel into a fine mist. Dirty injectors become increasingly inefficient atomizers with reduced fuel flow. Since only fully atomized fuel can combust properly, the engine's performance, economy, and exhaust emissions all suffer. Also, clogged injectors result in too lean a mixture, which, over time, can cause internal engine damage.


    Over time, some of the injector's internal parts, such as o-rings and those made of plastic, become brittle and less functional. This can result in fuel mixture problems and gas that is not fully burned before leaving the combustion chamber. This can easily damage sensors and your catalytic converter. But over and above worn or damaged components, by far the most frequent fuel injection problem is dirty or clogged injectors. Fuel additives can build up internally in the injector, and tiny rust or other particles in your fuel system can and frequently do lodge there.



    Clogged or Dirty Fuel Injector Symptoms:


    A lack of consistent engine power and uneven idling are signs that your injectors might be dirty. Misfiring is another symptom that could mean dirty or clogged injectors, but it could also result from heat- or time-induced internal damage to injectors.


    If the engine's RPMs fluctuate from high to low at idle or the engine hesitates under power, this indicates an inconsistent fuel flow, making injector problems your first suspect.


    Most professional shops that perform upper engine tune-ups will automatically replace the injectors. But if you have not had an upper engine tune-up done and have not had regular maintenance, you should probably start expecting injector problems, particularly if your car is either ten or more years old, or has more than 100,000 miles on the odometer. However, dirty injectors are a function of the overall condition of your car's engine, the fuel used, and the kind of driving you do. Because of these factors, dirty injectors can happen much earlier, so pay attention to the symptoms if they occur and drive with care.
