Particulate filter behaviour of a Diesel engine fueled with biodiesel

摘要: Abstract Biodiesel is an alternative and renewable fuel made from plant animal fat or cooked oil through a transesterification process to produce short chain ester (generally methyl ester). fuels have been worldwide studied in Diesel engines they were found be compatible blends with well operate modern Common Rail engines. Also throughout the world diffusion of biofuels being promoted order reduce greenhouse gas emissions environmental impact transport, increase security supply. To meet current exhaust emission regulations, after-treatment devices are necessary; particular Particulate Filters (DPFs) essential particulate A critical requirement for implementation DPF on powered engine determination Break-even Temperature (BET) which defined as temperature at deposition filter balanced by oxidation filter. fit within range line require minimum active regeneration during running, BET needs occur sufficiently low temperatures. In this paper, results experimental campaign modern, electronic controlled injection shown. The was fuelled either petroleum ultralow sulphur Biodiesel: evaluated both fuels. Results show that average, lower biodiesel than diesel fuel. final goal characterize device depending adopted fuel, taking into account different combustion nature matter. Overall suggest significant benefits use equipped DPFs.
