What is the leading cause of diesel injector premature failure?
Diesel injectors fail because of two main reasons. The first has to do with the mechanical soundness of the injector structure, and the second has to do with the quality of the fuel running through the injector.
What is the reason for injector failure?
Common causes of injector failure While many things can cause breakdowns, the most likely cause of premature failure is fuel contamination. Fuel contamination occurs when debris in the fuel gets past the filtration, destroying the sealing surfaces. Think microns, smaller than a human’s hair-sized, clearances.
How can you tell if your injectors are bad?
Typically, a car delivers a subtle rumble when at idle. If you notice that the sound has gone from low to a rough and unpleasant noise, it may be a sign of bad fuel injectors. That occurs when particles build up on the injector nozzles, thus affecting the amount of spray and atomization of fuel.
How do you know if you have a bad injector?
The most common sign of a bad fuel injector is the check engine warning light, which appears on the dashboard. As soon as an injector isn’t doing what it should, this light will come on. (In other words, if it’s adding too much or too little.)
What happens when injectors fail?
If a clogged fuel injector continually struggles to disperse fuel to the engine, a time will come when it misses the fuel supply completely and the engine will misfire. The misfire will easily be felt while driving, and often requires immediate repair by trained automotive repair specialists.
Are your diesel fuel injectors cleaned?
Clean fuel injectors are a must for peak performance of your diesel engine. Any of the symptoms above can indicate problems with your fuel injectors which shouldn’t be ignored. These include injectors that are dirty, clogged, or have a leak.
Do you have an injector problem?
But some problems may be tougher than your customer — or you — think. Take the diagnosis of an injector issue. The most common injector issue is when the engine produces a cylinder misfire. The misfire is generally associated with a loss of power and no unusual smoke. Like anything else, injectors can get tired and become weak over time.
What are the symptoms of a diesel fuel injector problem?
5 COMMON SYMPTOMS OF FAULTY DIESEL FUEL INJECTORS 1 Trouble starting the vehicle or uneven idling. The engine cranks but doesn’t start unless you crank it for a long time. 2 Smell of fuel. The smell of diesel inside the cabin means that the diesel has a leak somewhere. 3 Increased fuel consumption and poor miles per gallon.
What are the most common problems with electronic diesel engines?
The good thing about electronic diesels is that the technician can link up with a scan tool to analyze data in order to try to pinpoint problems. But some problems may be tougher than your customer — or you — think. Take the diagnosis of an injector issue. The most common injector issue is when the engine produces a cylinder misfire.
