Study on Fuels' and Detergents' Effect on Combustion Chamber Deposit Formation

摘要

(1) When detergents are added under running conditions at lower speeds and smaller loads, the formation of CCD is promoted, as CCD remains inside the combustion chamber almost in a state without chemical reactions. (2) Among the aromatics in gasoline, those with a large amount of substituents, and for those with multiple substituents, the ones that have them positioned adjacent to each other, generated little amount of CCD.
