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.
