Increase Fuel Lubricity
Lubricity increased 42 -48% on dosing
ratio 1:500 as tested on HFFR
iFleet fuel catalyst materially improves the lubricity of the fuel,
protecting injectors and pumps from premature wear and failure.
The product helps to combat problems associated with "diesel
spiking" and water, always a concern with outside filling.
This leads to prolonged and improved injector spray patterns, which
results in extended efficiency of the fuel-burning process, less
heat, less soot and improved all round efficiency.
is the friction between two solid objects touching one another,
this is expressed in units of N .Our current fuel specification
requires 460 N. This number is directly negatively affected by the
presence of water, contamination particles, heat and the ever abusive
presence of paraffin (A1).
Pressure in these injectors is commonly between 1600 -2500 bar,
with very small tolerances.
Fact: 50-75% of modern engine failures occur directly due to injector
engine failures caused by fuel with insufcient lubricity - A.J.
Avoid cheap diesel! There is a reason why it is cheap. It is very
profitable for end diesel suppliers to spike diesel with paraffin
(A1). It even happens at official oil company garage forecourts,
not just the "diesel wholesaler" on the corner. This phenomenon
also has a national footprint.
To protect one against this third party "spiking" that
is highly illegal and not recommended, we offer the fitment of an
onboard automatic dosing system which doses iFleet fuel catalyst,
in a ratio of 1:500. This will ensure that "spiked diesel"
with up to 20% dilution will remain well above the 460N required
(particle and water)
Proper filtration is the way to deal with this problem. Ensure that
filter holding capacities are not exceeded and that appropriate
micron filtration is maintained.
inspection of bowser for contamination is vital.
Water finding paste is a
good indicator of free water on the bottom of a bowser.
Fuel sampling from failed engines clearly demonstrates that lubricity
is one of the leading direct contributors of engine sezuires
The modern engine is extremely sensitive to low lubricity and injector
failure can occur in a short time frame, leading to costly engine

Wear in Injector
in diesel viscosity and lubricity can reduce the film thickness
to a point where metal-to-metal contact occurs.
Wear and Abrasive Wear
dented, cracking initiated
fatigue cycles, cracks spread
fails, particles released
- Improved lubricity can not restore worn spray holes to their
- Improved lubricity can however reduce the rate of deterioration
of injector spray holes.
- New injectors will stay new much longer if fed with higher
lubricity and clean diesel, Improves Viscosity and Lubricity
- Particles are trapped between surfaces.
- Surfaces dent and cracks start.
- The cracks spread even without more particulate damage.
- Spalls occur as surface material breaks away.
- Process is accelerated with thinner fuels of lower viscosity.
Wear in the sliding area between Plunger and Barrel will result
in a reduction in the injection pressure through the spray holes
and poorer atomization. Squirting and dribbling are believed to
be the cause of the very premature failures associated with liner
glazing and excessive carbon build up around the rings. Worn material
cannot be replaced, but improved lubricity and viscosity between
the Barrel and the Plunger can eliminate slow response and stiction.
Premium Diesel Fuel
Diesel fuel performs three major functions in a diesel engine:
- It supplies all the energy for the engine.
- It cools and lubricates the precision parts of the engine's
fuel pump and injectors.
- It enables emission controlled engines to meet regulated emission
Diesel engines will run on a great variety of fuels, but some
fuels will give better performance, higher efficiency, improved
reliability, or lower maintenance costs than others.
Fuel must be selected based on overall operating costs, not just
on price. Operators must select fuels to optimize performance and
