Contaminated diesel fuel accounts for a large number of fuel system failures in diesel engines. To ensure your back-up system doesn't fail when you need it, you need to ensure that your fuel does not become contaminated and that regular maintenance is completed on your equipment.
How does stored diesel become contaminated?
Diesel fuel can become contaminated very easily by a range of external factors. Fuel tanks have an external breather, this breather pipe can allow in moisture, dust and contaminated particles. Different air temperatures will cause any moisture to condense which will cling to the sides of the tank, this will eventually lead to corrosion. The water and rust will eventually sink inside the tank causing a chemical process which uses the additives in the fuel, this also causes oxidation and significantly reduces the fuel's energy efficiency as well as damaging the engine. Bacteria create an opaque layer within the fuel that clogs the engine filters and can severely restrict the flow of the fuel.
Diesel fuel, by nature, is unstable and tends to quickly break down into its constituent elements, it begins to degrade in as little as three weeks. That degradation usually results in the creation of gums and insoluble particles that do not dissolve back into the fuel. these gums are incredibly tack substances that tend to adhere to fuel injectors and fuel lines, which reduces the amount of fuel flowing freely into the combustion chambers and in turn, reduces productivity as well as damaging the engine.
How to stop stored diesel becoming contaminated
A fully automated fuel polishing system monitors the fuel in real time, maintaining its caloric value and will keep it clean and ready to use. Installing a fuel polishing system will not only reduce your fuel and maintenance costs, it will also prolong the life of your machinery.
