Exhaust emissions of a diesel engine fueled with soybean-oil-methyl-ester-diesel blends and their fuel properties
Biodiesel has been gaining worldwide popularity as an alternative energy source because of its many benefits.In order to optimize the application of biodiesel the low-temperature fluidity,pulverization,evaporation,invariability,erosion capability,cleanliness and mutual solubility of the low blending rate soybean-oil-methyl-ester biodiesel-diesel blends were compared and analyzed.Then the engine tests have been carried out with the aim of obtaining comparative measures of emissions such as CO,smoke density,HC and NOx to evaluate and compute the behavior of the diesel engine running on the low blending rate biodiesel-diesel blends.The experimental results show that the low blending rate biodiesel-diesel blends conform to the standard GB252-2000 of China.Compared with the original diesel engine,the smoke,HC and CO emissions of diesel engine fueled with low blending rate soybean-oil-methyl-ester decrease,but NOx emissions increase.
