Why Use These Additives To Diesel
Fuel?
Ignition Improvers
Ignition improvers facilitate an
economical increase of the cetane number with a correspondingly
positive influence on combustion and exhaust emission.
Organic nitrates are the active
ingredients. Ethyl hexyl nitrate has especially proven itself as a
commercial ignition improver.
Anti-wear Additives
Also known as ‘‘lubricity
additives’’, these products became necessary when low-sulfur and
sulfur-free diesel fuels were introduced.
Diesel fuels lose their natural
lubrication properties when hydrogenated to remove sulfur compounds.
Fatty acid derivatives are typical products and were also already
used earlier in aircraft turbine fuels.
Antifoaming Agents
Antifoaming agents assure easy
refueling and safe automatic shutoff of the fuel nozzle at a gas
station without the spilling frequently encountered earlier and thus
lower environmental pollution at gas stations.
Extremely low concentrations of silicon
fluids are employed. They are also used in engine oils to prevent
foaming in the crankcase.
