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.
