Dirty fuel and cleanup additives’ influence on injector clogging/coking

Tests aim to determine the influence of using “dirty” fuel on the formation of sediments and injector nozzle clogging/coking, as well as evaluation of the usage of cleanup additives. Modern diesel engines are equipped with injection systems which require fuels of the highest quality. Due to that fact, tests are conducted on the engine dyno with the aim of specifying the influence of elements like sodium and potassium on the propensity for sediment formation in the injectors’ nozzles at high temperatures, which results in a deterioration of spray formation, a decrease in engine performance and an increase in fuel consumption. Simultaneously, tests of cleanup additives – which decrease the formation of sediments and restore the original engine parameters – are conducted.
