IGNITION IMPROVERS, ANTI WEAR, AND ANTI FOAMING DIESEL FUEL ADDITIVES BASIC INFORMATION


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.
