Fuel injectors ensure the fuel gets into the engine optimally.Fuel injectors are regularly used in engines to keep their emissions cleaner, reduce the need for fuel system maintenance and increase fuel efficiency. Most fuel injectors consist of an injector body and nozzle. Fuel injectors typically last a long time without needing maintenance or replacement, but sometimes the two main parts may fail, harming your engine’s performance as a result. Learn more about troubleshooting and checking your injectors.
Symptoms of a Faulty Fuel Injector in Your Detroit Diesel Engine
Head off the problems that failed fuel injectors bring to your engine by learning more about the symptoms of a faulty fuel injector. By catching these signs early, you can reduce a defective fuel injector’s negative impact on your engine’s performance. Some common symptoms include increased fuel consumption, uneven idling and dirty emissions.
Below you can find out more about the primary symptoms of a faulty fuel injector:
Engine misfiring: An engine misfiring during ignition could be a sign your fuel injector is damaged. A misfiring engine is either a sign your engine doesn’t have enough combustion chamber heat or lacks proper fuel injection. You may not have enough fuel pumping into your ignition, or a cylinder’s fuel charge might not be igniting.
Uneven idling or problems starting the engine: One sign something is wrong with your engine is when it cranks but doesn’t start unless you crank for a significant time. There may also be an issue if you notice that while the engine is idling, it revs at various speeds.
Increased fuel consumption: If you see your engine’s fuel consumption going up, you may have an issue with your fuel injectors. Faulty injectors usually cause the engine to use more fuel, harming its efficiency and performance.
Dirty emissions: Clogged injector deposits or filters often cause an incomplete or uneven fuel burn. You can spot this problem by the engine’s emissions being dirtier and more noticeable.
Greater fuel smell: A major symptom of diesel injector damage is a more pronounced fuel smell. If you notice an increased fuel odor from the engine, your faulty injector may be causing the fuel to flow out of an inactive injector
It’s crucial to know the signs of a fuel injector going bad and the ways to check for problems, as the fuel injector can harm your engine’s performance. Even though a bad fuel injector doesn’t hurt your engine directly, it can create conditions that lead to a damaged engine.
