“There’s no question that the use of contaminated fuel in modern fuel systems can cause a host of problems with machinery,” says David Barker, a product support consultant in Caterpillar’s Global Mining Division. “But there are things sites can do to control the cleanliness of the fuel they use.”

CONTAMINANTS AND EFFECTS
4. HOW DIRT GETS INTO FUEL:
During Operation (Breather, Transportation, Filling)
Maintenance
Breakdown Of Rubber
Pumps, Motors, Tanks
EFFECTS OF DIRT AND DUST:
Small Particles: System components failure over time (injector wear, over consumption, loss of power)
Larger Particles: Immediate catastrophic failure (fuel pomp failure, injector blockage)
Typical particle size range in fuels is between 1-50μm
CONTAMINANTS AND EFFECTS
5. HOW WATER GETS INTO FUEL:
On delivery from supplier
Condensation in tank
Leakage into tank (rain, pressure washing, ground water...)
Ingress from atmosphere (humidity)
Human error (unprotected vents, fill ports, seals...)
EFFECTS OF WATER:
Contributes to Fuel & Additive Drop Out Problems
Promotes Rust, Corrosion, Deposits, Acid Formation and Algae Growth
Reduces Fuel Lubricity (when emulsified) and Flow (when freezes)
Plugs Injector Nozzles and can reduce Injector Life by up to 10x
Pitting And Cavitation
Promotes Microbial Growth

9. NEEDLE SURFACE WEAR:
Excessive overflow within injector
Too little injection
Bad atomization due to lower injection
pressure
Loss of power
MICRO DAMAGE IN INJECTORS
10. Lower injection pressure
Bad atomization
Fuel jet
Fuel drip
RESULTING IN:
Washing away of oil film -> seizing
Piston melting
Lubricant dilution -> bearing failure
PARTICLE RELATED ENGINE FAILURE MECHANISMS
11. Onboard filters are designed to provide final filtration for
moderately clean fuel. Engine filtration is not intended to clean
fuel contaminated with large amounts of dirt and water. If
contaminated fuel is used, the capability of the onboard
filtration is overwhelmed and injectors either wear out
prematurely or seize. This means more maintenance and
more downtime.

15. What is Efficiency?
The beta ratio is commonly used to calculate the filtration efficiency of a filter and can be
converted into a percentage of efficiency at a given particle size.
The formula used to calculate efficiency is:
What Is a Beta Ratio?
Beta ratio (symbolized by ß) is a formula used to calculate the filtration efficiency of a
particular fluid filter using base data obtained from multi-pass testing.
The formula used to calculate the beta ratio is:
where is a given particle size
(x)
ß = 50004(c)
Indicates that testing was done with
APC’s calibrated with NIST fluid
5000 times more particles
upstream than downstream that
are 4μm and larger
ß = 5000 is same as 99.98% @ 4μm
4(c)
ß5000 is 99.98% for particles 4μm and greater

• Without Beta Ratio / Efficiency information, Micron rating
alone is meaningless.
• Focus must be on Beta Ratio, rather than just Efficiency %,
as we can see below, 98.70% & 99.98% might not sound
too big of a difference but in Filtration World, that’s a huge
difference.
