Effect of Cetane Number Improver on Emission Characteristics of Methanol/Diesel Blend Fuel

Abstract:

The influence of cetane number improver on emission characteristics of diesel engine fueled with methanol/diesel blend fuel was investigated. Methanol/diesel blend fuel was prepared, in which the methanol content is 10%, different mass fraction (0%，0.5%) of cetane number improver were added to the blend fuel. Load characteristic experiments at maximum torque speed of the engine were carried out on 4B26 direct injection diesel engine. The results show that, compared with the engine fueled with diesel, the CO emission increases under low loads and reduces under medium and high loads, the HC emission increases, the NOx emission decreases under medium and low loads and increases under high loads, the soot emission reduces significantly when the diesel engine fueled with blends. When cetane number improver was added to blends, the CO and NOx emission reduces, the HC emission decreases, the soot emission increases to some extent compared with the methanol/dieselblend fuel without cetane number improver.
