Issues with Modern Diesel
Diesel starts to degrade from the moment it leaves the refinery and enters the supply chain. This process is intensified through the addition of Biofuel. Even top grade diesel goes through this process of degradation as it is a natural occurrence and this degradation continues while in the storage tanks and occurs in 2 ways:
1. Condensation which takes place inside the tanks either storage of equipment/vehicle tanks. Diesel contains dissolved water & when humid air reaches the inner reservoirs, climate conditions generate temperature variations inside the tank, this, in turn, causes an acumination of water on the top of the tanks. The acuminated water condenses, and when it falls together with pieces of metal/plastic it contaminates the fuel in the tank.
This sets of a chain of problematic reactions which degrades the fuel & forms Sludge”:
- The development of micro-organisms Bacteria, Fungi, & Yeasts.
- The oxidation of the fuel due to the presence of air and water in the tanks.
- Corrosion of metallic tanks & erosion of plastic tanks.
2. When more Biofuel is added to diesel, there is a corresponding reduction in the content of sulphur. Sulphur is a natural element that prevents the proliferation of micro-organisms, and when reduced will cause the increasing formation of sludge & sediments as a result, which causes obstructions in the whole fuel system.
- Fuel pumps
- Conduit pipes
- Pick up tubes
This degradation of the diesel harms the performance of the fuel, which in turn harms the performance of the engines it is used in, leading to users seeing a loss of power resulting and other problems associated with blocked fuel filters and injectors.
