Customers Fieldtests Comm. Diesel engines continuously re-circulate the fuel. The surplus not used in combustion goes back to the tank through the return line, aggravating the process of fuel degradation. These units are bidirectional, direct flow-thru and self cleaning, no moving parts, no electrical hookup. Diesel engines use only part of the total fuel flow for combustion, the surplus goes through the return line and back to the tank.
Leftover particles pass through filtration and burn in combustion.
Hydrocarbon Distillates such as diesel fuel, gasoline, jet fuel, hydraulic oil, etc. are organic fluids. They are food for bacteria, fungi, yeast and mold that rapidly deteriorate the quality of the fuel. Modern refining techniques, additives, fuel storage and transport systems all contribute to contamination and are determining factors in the shelf life of fuel. Additives, in particular those rich in nitrogen and phosphorus, enhance microbial growth and accelerate the process of biodegradation. Biosurfactants, enable water to emulsify into the fuel, spreading and increasing the damaging effects of microbial contamination.
