Fuel Filter Plugging
Advances in diesel engine technology have transformed vehicle
performance. Today's engines are more powerful and more
efficient resulting in lower emissions.
At the same time there has been the shift towards new age fuels.
These have been introduced to help reduce the environmental impact
of exhaust emissions. Ultra Low Sulfur Diesel (ULSD) contains less
than 15ppm sulfur and is a cleaner alternative to traditional
However, the hydrotreating process used to remove sulfur from
refinery streams has severe effects on fuel properties. When used
in a modern diesel engine, ULSD can lead to deposit contamination
because of the extreme heat and high pressures generated by
advanced fuel injection equipment.
The two known issues that affect high performance diesel engines
operating on ULSD are premature fuel filter plugging and the
formation of deposits in the high pressure fuel injection (HPFI)
Under the extreme high temperatures and pressures present in
modern diesel engines, ULSD is thermally decomposed in the
injection system. This process results in fuel filter plugging.
Black soot like deposits form in the fuel filter.
Field tests with heavy duty vehicles show that fuel filter plugging
can occur after just 10,000 to 12,000 miles in operation. Filters
are often found to be completely blocked with black soot and need
Using ECOCLEAN® HPFI Antifoulant, reduces fuel
filter plugging dramatically. Field tests suggest the filter
lifecycle is extended to the scheduled PMI of approximately 30,000
miles from between 5,000 and 12,000 miles. It is estimated that
savings on fuel filters alone could cover the cost of using
ECOCLEAN® HPFI Antifoulant.
ECOCLEAN® HPFI Antifoulant is a new fuel
additive created specifically to improve the performance of ULSD in
newer model vehicles equipped with high pressure fuel injectors.
ECOCLEAN® HPFI Antifoulant has been designed to combat the
problem of fuel filter plugging
Historically the problem of fuel filter plugging and preventing
deposits was combated using traditional detergents but these
products are proving less effective in modern heavy duty diesel
engines. The treat rates required to have any impact are simply not
practical and so the problem of fuel filter plugging must be
tackled in a different way.
ECOCLEAN® HPFI Antifoulant is a highly innovative
multifunctional middle distillate fuel additive that offers a
number of important benefits to fleet operators. It prevents the
formation of fuel soot by conditioning ULSD to withstand the
extreme temperatures and high pressures of today's fuel
This new fuel additive not only maintains the thermal and oxidative
stability of ULSD, it also prevents the formation of black sludge.
This is a common problem but it can be made worse in high pressure
engine units operating at high temperatures. Contaminants from
unburnt fuel and combustion soot build up over time to form a thick
black sludge. Sludging ultimately affects performance.
Thanks to ECOCLEAN® HPFI Antifoulant it is possible
to push the performance of ultra low sulfur fuels to a new level.
The additive not only helps to keep maintenance costs low.
ECOCLEAN® HPFI Antifoulant also boosts power in
today's high-tech engines and helps the environment by reducing
exhaust emissions and improving fuel economy.
