Summary:

AbstractSince Euro 5 standard, Diesel Particulate Filter (DPF) technology has been widely introduced in Europe and Fuel Borne Catalysts (FBC) provide a powerful solution to achieve regeneration in all driving conditions. Ongoing new emission regulation constraints of Euro 6.b (2014) and forthcoming Euro 6.c standard in 2017, that will reduce the gap between emissions during homologation and in real driving conditions, will demand the support of optimized FBC formulated with Deposit Control Additive (DCA).This paper presents the impact on DPF regeneration performance of advanced FBC with a sharp particle size distribution of reduced nanoparticle size diameter. Small particle size FBC gives enhanced DPF regeneration, allowing regeneration at lower temperature (id est improving fuel economy) but also lower dosing rates in fuel. Thus, this implies reduced filter ash content and an extended maintenance interval. This FBC formulated with DCA also demonstrated in several types of bench tests a positive effect on various deposit types by preventing the formation of injector nozzle coking deposits in older and modern diesel engines as well as Internal Diesel Injector Deposits (IDID). Moreover, this FBC exhibits high stability and compatibility in some new advanced biodiesel blends, namely based on animal or used oil methyl ester. Finally, FBC technology is compatible with Selective Catalytic Reduction on-Filter (SCRF) technology. Regeneration efficiency is not affected by FBC and NOx conversion is maintained during regeneration
