Fuel contamination often results in fuel injection system malfunction and engine breakdown.
The fuel oil of diesel engine could be contaminated with water and solid particles such as silica, rust, or alumina. It may result in improper functioning of the fuel combustion injection equipment. Water contamination leads to sulphuric surface corrosion, rusting and misfiring in the combustion stroke. Hard particles, silica or alumina, produce abrasive wear on the needle and guide and cause the leakage of fuel. Any catalysts and fines entering the clearance spaces of part of fuel injection equipments can lead to accelerated wear of these parts. The wear may be extensive with few days of operation with contaminated fuel. Also it will block the injection holes on the nozzle and cause complete malfunctioning of the fuel injection system.
