摘要：

The objectives of this study are to investigate the effect of diesel fuel blend with biobutanol on the emission of turbocharged CRDI(common rail direct injection) diesel engine. The blends considered here were blends of diesel fuels with 10 and 20% (by vol.) n-butanol. Engine performance and emission characteristics were measured by the ESC(European Stationary Cycle) test. Emissions of HCs, CO, NOx, HCHO, HCOOH and NH3 were measured by the FTIR. Size and number distribution of particulate matter were measured by the SMPS. From the results, for the n-butanol blend, NOx emission increased compared with the neat diesel fuel case. At the case of 20% butanol, both THC and CO emissions increased significantly, and both HCHO and HCOOH increased modestly in the low loading of ESC 7, 9, 11 and 13 mode comapring with the neat diesel fuel case. While n-butanol blending with diesel fuel reduced the mass of PM by 50 similar to 73%, it emitted ultrafine particles (Dp<200nm) slightly more. (C) 2014 The Authors. Published by Elsevier Ltd.
