Some Common Fuel Problems
Water, rust and dirt accumulate in the bottom of storage tanks. Water either
from leakage and/or condensation.
The oxidation process of fuel results in the production of gums and sediments.
The fuel in storage tanks can sometimes develop a dirty slime at the fuel/water interface.
Apart from being unsightly it can block tank strainers and vehicle fuel filters. If left
unattended it can spoil the
fuel and contribute to tank corrosion.
The most common
contamination is from Cladisporium Resinae.
These airborne spores
which occur naturally in diesel, have an oxygen source from the water and use the elements
as a food source to propagate growth.
It becomes evident
because of the fact that filters clog up, vehicles may lose power and their overall
The conventional method
of eradicating the bug is to use a biocide. However, this has two major drawbacks in that
both the water and the dead bug remains in the system and removal is costly.
WAXES & RESINS
Sulphurous acids cause the build up of waxes and resins on injector pintels and, which may
leach into oil components.
The warnings are piston
rings sticking or the rings and cylinder lines wearing to the point of excessive blow-by
or oil consumption. As these warnings are not dramatic but accurate over time engine users
attribute the gradual drop in performance due to the age of the vehicle.
During combustion, sulphur in fuel forms various sulphur oxides which combines with the
moisture in the intake air to produce sulphuric acid. This acid accumulates in the engine
lubricating system. Suspended in the oil, it chemically attacks cylinder lines, piston
rings, exhaust valve guides and other engine parts.
The problem can get worse:-
The more mileage
traveled the greater the fuel consumption, the greater the sulphur intake.
The higher the
sulphur content through minimal refining the larger the acid content.
High humidity aggravates
fuel sulphur wear.
When engines operate at
lower than normal temperatures moisture condensation increases. This depletes the oil
additives and combines with sulphur in the fuel to make more acid.
Increased oil consumption.
Increased crankcase blow-by.
Vapour visible in the crankcase blow-by.
Black exhaust smoke.
