The Purpose Of Detergent And Corrosion Protection Additives

Detergent Additives
Diesel fuels can form carbonaceous deposits in injection nozzles and thus alter the injection characteristic while adversely influencing the combustion cycle and exhaust emission. A whole series of complex organic compounds is capable of preventing nozzle coking.

The active ingredients continuously have to be adapted to injection technology. Developments of new additives necessitate elaborate tests in complete engines, preferably under realistic operating conditions.

Suitable detergent additives are derived from groups of amines, amides, succinimides and polyetheramines for example.

Requirements for ‘‘cleanliness’’ and a diesel fuel’s detergent effect keep increasing as advances in diesel engine development continually increase injection pressures while reducing the size of nozzle holes

Corrosion Protection Additives
Anti-corrosion additives are particularly necessary when small quantities of water have infiltrated the fuel, e.g. condensation during longer downtimes. Polar molecular groups of esters or alkenoic succinimide acids build up a monomolecular protective coating on metallic surfaces and prevent direct contact with water and acids.
