ECOCLEAN® HPFI Antifoulant

ECOCLEAN^® HPFI Antifoulant was developed by Innospec Fuel Specialties in direct response to the performance issues surrounding modern diesel engines and new age fuels. The product is the latest addition to our impressive LEGAL DIESEL^® range of diesel fuel additives. It complies with the federal low sulfur content requirements and does not exceed 15ppm.

To understand the benefits of ECOCLEAN^® HPFI Antifoulant it is important to appreciate how recent advances in engine and fuel technology have impacted on vehicle performance and fleet maintenance costs.

The technology at the core of the modern diesel engine is very sophisticated and developments like high pressure common rail (HPCR) direct fuel injection have transformed vehicle performance. Today's engines are more powerful and more efficient resulting in lower emissions.

Alongside advances in engines technology we have seen a major 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 diesel fuels. With its use now mandatory under EPA legislation, this fuel has quickly gained acceptance across the United States. It is also used extensively in Canada.

While the introduction of ULSD is to be supported, it should be recognized that the hydrotreating process used to remove sulfur from refinery streams has severe effects on fuel properties.

Removing the sulfur not only affects a fuel's natural lubricity, the process also removes nitrogen and oxygen. Without these naturally occurring components there can be problems with the fuel's low-temperature handling, thermal stability (vulnerability to peroxide formation) and corrosion potential.

This presents the fuel industry with the challenge of extracting maximum performance from today's super-efficient engines while working with more problematic, yet environmentally friendly, ULSD fuels.

Innospec was quick to realise how this would ultimately impact on fleet operators unless an additive like ECOCLEAN^® HPFI Antifoulant could be developed to address two critical performance issues.

Modern diesel engines operating on ULSD can be negatively affected by deposit contamination because of the extreme heat and high pressures generated by advanced fuel injection equipment.

First, stubborn deposits build up around the injector valve seat and nozzle, inhibiting fuel flow and adversely affecting engine performance. Second, black soot like deposits form in the fuel filter as a result of ULSD being thermally decomposed. The fuel decomposes in the injection system where there are enormous differences in pressure and temperature.

Both injector fouling and fuel filter plugging lead to increased maintenance costs on heavy duty vehicles fitted with modern diesel engines. ECOCLEAN^® HPFI Antifoulant was designed to resolve these problems. ECOCLEAN^® HPFI Antifoulant is an exciting new fuel additive that can help fleet owners and operators reduce maintenance costs.

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.
