摘要：
Experimental tests were conducted to evaluate the engine performance and emission of a diesel engine with diesel fuel and simulated bio-oil blends. The simulated bio-oil was prepared based on the refined biomass fast pyrolysis bio-oil with pure substances (analytically grade), and the fuel blends containing 10% and 20% by volume of simulated bio-oil were named as B10 and B20. Results indicate that the engine power for the B10 and B20 are about 3% and 7% lower than for the pure diesel fuel. The average drop of brake specific energy consumption for the B10 and B20 is about 7% at full-load. The measured products of the imperfect combustion of fuel, such as CO and HC, were reduced notably for the B10 and B20 compared with the diesel fuel at medium and high loads, which the NMHC emission decrease was about 75% at full-load. Under full load conditions, the smoke emission characteristics of B10 and B20 were different with diesel fuel, and the average reduction of smoke opacity was about 10% for B20 relative to B10. ©, 2015, Zhejiang University.
