About Fuel Injectors


Because the injector is responppt-fuel-injector-3sible for pressurizing the fuel and injecting it into the combustion chamber, it is an understandably complex part of your diesel engine. It's all about timing. The injector needs to be perfectly timed for maximum power. This has led to the manufacturing of multiple kinds of injectors to help improve the process. You can read more about two of the most popular types—common rail and unit injectors—in our past blog.


So, in short, the fuel injector functions as the primary fuel delivery system in your engine. It's what atomizes the fuel going into the combustion chamber. The injectors mix the fuel with air and release it into the chamber as a high pressure spray. Wonder why that's important? It's this process that gives you the fuel economy and power that you want out of your vehicle.


Fuel Injector Problems


Have you noticed excessive smoke? Low power? Poor fuel economy? These signs might mean that your fuel injector is starting to go bad. Check out these common signs of fuel injector failure.


Normally, your injectors help you achieve great fuel economy and engine power, but when they're not working right, this efficiency will likely decrease. You'll also want to keep an eye out for engine misfires, rough idle or engine performance, excessive exhaust smoke, or engine knocking, as these could also indicate that something is going wrong with your diesel injectors.


Any of the following problems could be the reason your injectors fail. Be sure to watch out for:


  • Air or water in the fuel system
  • Secondary damage from another engine failure
  • Age or wear
  • Clogs
  • Cracks
  • Leaks from busted seals
  • Other Leaks
  • Failure of internal components
  • Blown injector tip
  • Poor timing


Our past blog can help you identify your faulty injector so it can be replaced.
