Water is commonly found in diesel fuel due to condensation, handling and environmental conditions.
Water is the most damaging contaminant found in diesel fuel, and it is the primary cause of additional fuel breakdown and has been causing severe problem of engine-damage to vehicles all over the world, costing their owners thousands of dollars in repair bills.
Although most of the diesel fuels generally have small quantity of dissolved water content which is normal and harmless. Typically at room temperature this dissolved water content could be less than 200 ppm . As water content increases or goes over the saturation point or when the diesel cools down, it can no longer exists as dissolved water and becomes present as free water. The water content becomes critical and damaging at concentrations above 200 ppm, so effort should be made to keep water contamination as low as possible. The effects of high or continuous water contamination can lead to: |
