The key causes of injector failures are:
- Fuel Contamination
- Poor Fuel Filtration
- Incorrect Installation
- Non-OEM approved remanufactured products
The majority of diesel engine problems stem from
contaminated fuel. Common problems include corrosion
from excessive water in the fuel, micro fine particles in the
fuel and improper fuel storage, which is caused by water in
the fuel.
There are two ways in which water can get into the fuel:
through the delivery system and through the tank vent.
Fuel Contamination ~ What Can I Do?
Solution: Always purchase fuel from a reputable service
provider and use a proper fuel/water separator. Periodic
inspection of the vehicle’s tank vent is also recommended.
A common problem with diesel injectors is erosion of
the control valve. The heart of the common rail injector
is the valve through which fuel passes at extremely
high pressure. The passage opening is sealed using
a pressurized ball that is only 1mm in size. A proper
seal is critical for exact injector performance. Abrasive
contaminants, released by inadequate filtration, can erode
and damage the control valve and not allowing the ball to
seal. This can lead to excessive smoke, starting or idling
problems and potential engine failure.
Poor Fuel Filtraton ~ What Can I Do?
Solution: To ensure exact performance within the
designed service life of the injector, use only OE filters or
filters having the same OE micron rating and follow the
recommended OE filter change interval. Using anything
less can cost you more in the long run.
