The properties of diesel fuels have changed distinctly, especially in the United States. Fuel-related problems-one of which is the injector-nozzle coking in passenger-car diesel engines-have arisen due to deteriorated fuel qualities. Extended investigations of road-tested diesel engines suggest a link between fuel stability and the coke-deposit mechanism. Stabilizing poor-quality fuels by a chemical-additive package resulted in troublefree operation over extended mileage. Thus fuel stability, which evidently has to be secured at the refinery, shows up as an important property for satisfactory engine operation.
