Summary:

AbstractEngine dynamometer tests were conducted to evaluate the effect of detergent additives and gasoline components on Combustion Chamber Deposits (CCD). Additives with polyether amine (PEA) and with polyolefin amine (POA) chemicals were used. Three kinds of POA additives were used. Our results show that some kinds of additives and aromatics in gasoline increase CCD formation. Different polyolefin detergents show different tendency of CCD formation.The amount of CCD showed good relationship with the unwashed gum level of the gasoline. In general, smaller dosages produce less CCD. This means that detergents which have good IVD and PFID effectiveness at smaller dosage are better with regard to CCD.We analyzed the CCD by C13-NMR, GPC and IR method. The detergent contributes to CCD.Vehicle emissions tests were carried out to evaluate the effects of CCD on exhaust emissions
