- Summary:
- Diesel Particle Filters (DPFs) using a fuel-borne catalyst toassist filter regeneration provide a uniquely advantaged DPFtechnology. More than 5 million diesel passenger cars in the markettoday are equipped with this after-treatment system. Based on thisextensive field experience, improvements have been made to thedurability and maintenance requirements of this technology, and thetotal system cost has been optimized. Recently, a new fuel-bornecatalyst, Eolys Powerflex (named new Fe-based FBC) has beendeveloped to provide solutions that comply with current Euro 5 andforthcoming Euro 6 requirements that take into account bothregulated emissions and optimization of CO₂ emissions.This paper presents the benefits of this optimized product. Thesoot oxidation activity of this new Fe FBC has been tuned to ensurefast and complete regeneration at low temperature and very lowdosing rates in the fuel, thus reducing ash accumulation andimproving the overall system durability. In addition to its basiccatalytic properties, this product makes the complete exhaustemission control system more flexible towards all new types offuels, particularly those containing biodiesel blends. It reducesmaintenance requirements and maintains the power and emissionsperformance of diesel engines throughout their life. This isachieved by keeping fuel injection equipment clean.Combined DeNOx and DPF systems are being explored as a means ofmeeting the EURO 6 standard. Fuel-borne catalysts are of greatinterest in these systems. This paper describes several possiblelayouts that minimize CO₂ emissions while keeping good DPFregeneration performance.Finally, the use of fuel-borne catalysts in light- andheavy-duty vehicles, and in retrofit systems for off-road equipmentand commercial vehicles will be reviewed
