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.

Lubricity 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 failure.

Diesel engine failures caused by fuel with insufcient lubricity - A.J. von Wielligh

Parrafin (A1)
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 lubricity level.

Contamination (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.

Periodic 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 failures.

Material worn from the spray holes cannot be replaced

Microscopic Wear in Injector
Reductions in diesel viscosity and lubricity can reduce the film thickness to a point where metal-to-metal contact occurs.
Fatigue Wear and Abrasive Wear
Particle caught	Surfaces dented, cracking initiated
After "N" fatigue cycles, cracks spread	Surface fails, particles released

• Improved lubricity can not restore worn spray holes to their original state.
• 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:

1. It supplies all the energy for the engine.
2. It cools and lubricates the precision parts of the engine's fuel pump and injectors.
3. It enables emission controlled engines to meet regulated emission levels.

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 emissions.

Clearances between the Barrel and the Plunger are often as little as 2.5 Micron and smaller
