MICROSCOPIC VIEW OF CONTAMINANTS
There are many different types of contaminants that could adversely effect, damage or even destroy a fuel injection or a hydraulic system. Bacteria, fungus, water, suspended microscopic particles, additives, wax are some of the main contaminants. Below are some examples of suspended microscopic particles and how they appear under a microscope. The size varies from 4-120 micron.
This is what a typical fuel sample patch looks like under a microscope. Careful observation reveals various different types of microscopic particles such as silica, bright metal particles and asphaltenes.
Presence of water in the transfer chain speeds the oxidation and chemical breakdown of the fuel and is considered very dangerous. Particle size vary from 10 - 120 micron range.
We have observed presence of fibers in fuel samples across the region. We strongly believe they are introduced into the fuel tankers and into the fuel storage tanks by improper cleaning and maintenance practices.
By-products of fuel as it oxidises. Asphaltene particles are generally thought to be in the 0.5 - 2.0 micron range and they agglomerate into an oily sludge. This problem is made worse when free water is present.
Bright Metal Particles
Typically comes from component wear such as fuel pumps and valves. These particles are abrasive and, as a result, can lead to wear and tear of the engine parts and ruin fuel injectors.
Silica And Dust Particles
This is typically airborne contamination or part of sludge from the bottom of tanks. U shaped open vents/pipes on top of storage tanks also increase its number significantly. Particle size varies from 4 - 40 microns and is extremely abrasive against delicate engine components.
