Abstract
EN The intense and multidirectional development of internal combustion engines, forced by tightening environmental regulations, has necessitated the verification and definition of new requirements for engine fuels. The article presents an experimental analysis of the ethanol or butanol admixture effect on the SI DI engine injectors contamination process based on engine and fundamental research. Injectors were evaluated after Keep-Clean only and Dirty-Up (Keep-Clean) tests, along with the Clean-Up test in accordance with CEC F-113-KC and CEC F-113-CU test procedures. The positive effect of the detergent additive on the ability to wash out injector deposits was demonstrated. A reduction of more than 80 percent in the duration of injection compared to the contaminated system was achieved. It was proven that the use of the detergent additive in the Clean-Up procedure makes it possible to return the injectors to full efficiency, which confirms the thesis of the leaching of injector nozzle deposits of SI DI engines.
