What happens when a diesel injector fails?
Over time, diesel fuel injectors wear out and fail to close completely. When this happens they cause a leak-down, resulting in a reduction of fuel pressure across the fuel rail. This can cause a difficult- or no-start condition as well as a smokey exhaust.
What causes diesel injector failure?
Why do fuel injectors go bad? Fuel injectors will fail when debris (water, dirt particles, etc.) or rust find their way into the system and, after time, plug up the nozzle, the armature, or the nozzle needle gets stuck.
Can a bad diesel fuel injector damage the engine?
Left too long, a faulty fuel injector can cause serious engine damage that requires major repair. Fuel injector problems can eventually lead to a breakdown, or in extreme cases, an accident if your engine fails while traveling at speed on the highway.
Can you replace one diesel injector?
Yes, you can replace just one of the fuel injectors in your vehicle. If you are facing a problem with an injector, you can swap it for a good cylinder.
Why do diesel injectors fail?
Why Do Diesel Fuel Injectors Fail? There are two major causes of diesel fuel injector failure associated with the properties of the fuel itself: excess wear and deposits. One mode of injector failure is excess wear. The less lubrication the fuel provides, the larger the wear scar.
What are the problems with a bad fuel injector?
A faulty fuel injector can cause the vehicle to experience misfires, a loss in power and acceleration, a reduction in fuel efficiency, and in severe cases can cause stalling or prevent the engine from running at all.
What are the symptoms of a faulty fuel injector?
– Rough Idle or Engine Stalls. Because your vehicle is not getting enough fuel or an uneven supply of fuel, the RPM while idling drops below the optimal level and results in a rough or even violent idle. If the RPM falls too low, the car will actually stall and you will need to restart…
What happens when fuel injectors go bad?
Engine missing, along with a rough idle, is a common symptom of a bad fuel injector. A bad fuel injector can restrict or stop fuel flow from being injected into an engine cylinder properly, which can negatively impact fuel combustion and affect engine performance, resulting in missing, a rough idle or misfiring.
What is a bad fuel injector?
A car that has a bad fuel injector will often have a rough, or choppy, engine idle. A fuel injector is responsible for injecting fuel directly into the engine cylinder where it is burnt during combustion; if this fuel delivery is compromised, a rough engine idle can result.
