DIESEL FUEL ADDITIVES BASIC INFORMATION AND TUTORIALS

Why We Use Diesel Fuel Additives?

The production of modern standard diesel fuels is all but impossible without additives. The partly conflicting properties of the individual components (molecular groups) must frequently be equalized by additives to satisfy the high requirements for operational safety, rate of heat release and exhaust emission throughout an engine’s entire service life.

This has undergone a definite change in recent years. As a rule, more varieties and quantities of diesel fuels than gasolines are additized. With the exception of antifoaming agents, all additives

consist of purely organic compounds.

What Are The Types Of Diesel Fuel Additives?

Described in more detail below, the most important groups of additives, are:

– flow improvers and wax anti-settling additives that improve winter capability, – ignition improvers that shorten ignition delay and improve combustion performance,

– anti-wear additives that protect injection nozzles and pumps;

– antifoaming agents that prevent foaming and spilling when pumping fuel,

– detergent additives that keep injection nozzles and fuel systems clean,

– anti-corrosion additives that protect fuel systems and

– antioxidants, dehazers and metal deactivators that improve fuels’ storage stability.

Odor masking agents are also used occasionally. Antistatic additives are used during manufacturing and subsequent redistribution (logistics) to the extent they are necessary to prevent electrostatic charging at high pumping rates.

The use of biocides to prevent fungus infestation on tank bottoms in the water/fuel phase may be foregone when fuel distribution systems are serviced regularly.
