柴油机燃烧茶籽油废气中碳粒对大气污染研究

生物能源已开始成为今后农用柴油机燃料重要能源,特别是作为农用汽车和载重汽车的代用燃油。为此,以茶籽油做S195型柴油机燃料进行了燃烧特性试验研究。为进一步改善茶籽油燃烧特性,将茶籽油经过技术处理,并采用扫描电子显微设备对废气中的碳微粒进行电子显微扫描测定和对大气污染的分析研究。结果表明:在柴油机结构基本不改动的情况下,燃用经过处理的茶籽油或茶、柴混溶油是可行的。经过处理的茶籽油比直接燃用茶籽油的燃烧性能好,废气中的碳微粒减少,排气对大气污染下降。

Pollution of Exhaust Air of Diesel Engine Burning Tea-seed Oil

Bio-energy is becoming one of the important energy sources for agricultural diesel engine,especially for the alternative fuel of agricultural automobile and truck.According to the results of burning character research of tea-seed oil on diesel engine,material handling was applied to the tea-seed oil to improve the burning character.With the processed oil,burning test was carried out on the S195 diesel engine,and micro electronic scanning apparatus was applied to measure the carbon particle in the exhaust air.And the result shows that it is feasible to burn mixture oil of tea-seed and diesel oil without changing the basic structure of the engine while with better burning performance,the exhaust contaminant drops.So the tea-seed oil undergone material handling has better burning character than the diesel oil or the mixture of tea-seed oil and diesel oil without material handling.
