Diesel fuel can get contaminated through various means. Physical environmental factors such as rainwater seepage, condensation, and coalescing are some primary influences. Additionally, contamination problems can arise from issues like tainted or adulterated diesel, insufficient filtration, poor maintenance, and neglect.
Fuel injection, replacing carburetors in the 1980s, has enhanced engine performance. The system, managed by the vehicle’s computer control unit, adjusts fuel delivery in real time based on various factors for optimal efficiency.
