Injector Fouling

New age fuels have rapidly gained acceptance across the United States and Canada as a way to reduce the environmental impact of exhaust emissions. Ultra Low Sulfur Diesel (ULSD) contains less than 15ppm sulfur and is simply a cleaner alternative to traditional diesel fuels.

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. These injection systems produce temperatures and pressures that are considerably higher than those found in older diesel engines.

The two known issues that affect high performance diesel engines operating on ULSD are premature fuel filter plugging and injector fouling. Injector fouling occurs when deposits form in the high pressure fuel injection (HPFI) system. Particularly stubborn deposits form at and around the injector valve seat and nozzle. The result of injector fouling is injector drift, power loss and an increase in smoke emissions.

Traditional detergents may have historically been effective in combating injector fouling but these products are proving less effective in modern heavy duty diesel engines and the treat rates required to have any impact are simply not practical. At the same time, the need to remove deposits in and around the injector valve seat and nozzle has become even more critical to overall performance.

ECOCLEAN^® HPFI Antifoulant is a highly innovative multifunctional middle distillate fuel additive that maintains the thermal and oxidative stability of ULSD. It offers a number of important benefits to fleet operators.

By conditioning ULSD to withstand the extreme temperatures and high pressures of today's fuel injection systems, ECOCLEAN^® HPFI Antifoulant helps prevent the formation of fuel soot. ECOCLEAN^® HPFI Antifoulant also cleans up existing injector fouling deposits, returning injectors to "like new" condition within a short time period.

With injectors cleaned and maintained in top condition, operators can expect fewer injector failures and optimum combustion at all times. This makes for a more efficient running engine that benefits from restored power, reduced emissions and better fuel economy.

ECOCLEAN^® HPFI Antifoulant has been trialed with a number of major fleet operators to see what effect using our additive had on a working fleet in terms of reducing maintenance costs. The results are impressive.

One customer reported no occurrence of injector fouling after starting to use ECOCLEAN^® HPFI Antifoulant. They also noted a substantial increase in fuel economy during the trial period. On the strength of these results, the fleet director recommended the use of ECOCLEAN® HPFI Antifoulant at all of their company's locations.

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.
