【摘要】 生物柴油是由植物或动物脂肪通过转酯化反应而得到。生物柴油的无毒性、可生物降解性和可再生性促使其受到越来越多的关注。研究表明生物柴油的性质和普通柴油相似,因此能直接用于发动机上而不需要改动发动机的结构。本文分析了实验室从餐饮废油制得的生物柴油的理化性质,以YC6M220G增压柴油机为研究对缘,进行了纯柴油和生物柴油与柴油的混合燃料在柴油机中应用的试验研究。试验结果表明:在柴油机不进行任何调整情况下,燃用生物柴油能保证柴油机的动力性能基本不变;初制的生物柴油排放效果一般,但是精制的生物柴油明显降低了柴油机微粒、烟度、HC和CO排放,是一种理想的替代燃料。更多还原

【Abstract】 Biodiesel is a fuel, which can be produced by chemical process of reacting vegetable oil or animal’s fats with methanol/ethanol under the catalytic effect. Biodiesel is being paid an increasing attention as an alternative, non-toxic, biodegradable and renewable diesel fuel. Previous studies have shown that the properties of biodiesel are very close to those of diesel fuel, and biodiesel therefore can be used in diesel engine with little or no modification on engine structure. The analysis of biodiesel produced from waste cooking oils in our Lab is made and their application on a YC6M220G turbo-charge diesel engine is studied in this paper. The testing results show without any modification to diesel engine, dynamical performance keeps normal when using biodiesel blend fuels, and the crude biodiesel leads to unsatisfactory emissions whilst the refined biodiesel reduces significantly particles, smoke/soots, HC and CO emissions thereby appearing a promising alternative fuel to petro-diesel fuel.更多还原
