Abstract
Research on the water-resistance, solubility of ethanol and biodiesel, the comparison testing research of economic and emission performance has been done on the ZS195 diesel engine when being fueled with biodiesel, ethanol-biodiesel, hydrous ethanol-biodiesel and pure diesel. The results indicate that B90E10 and B90A10 mixed fuel have good physical stability at 20 ℃. The brake specific fuel consumption of biodiesel, B90E10 and B90A10 is higher than pure diesel. The CO emission is equal to pure diesel at small load, while declining at big load. The Noχ emission is higher than pure diesel at small load while B90El0 and B90A10 blends decreasing successively, and B90A10 is lower than that of pure diesel. NO, emission of the three kinds of fuel are nearly e-qual at big load, which is higher than pure diesel. The THC emission is less than pure diesel, and the declining range of biodiesel is the largest while the case of that for B90E10 blend is the least. The smoke emission of carbon declines larger than pure diesel, and declines successively with the increasing of oxygen that the fuel contain.关键词
