摘要 生物柴油具有含氧低，十六烷值高，不含芳香烃和硫，降低发动机污染物排放的特点，能够与国标柴油混合或单独用于汽车及机械质量影响因素SCI、CNKI、Google检索工具甘油酯脂肪酸、环烷酸 Abstract Biodiesel has a low oxygen, high cetane number, free of aromatics and sulfur. It can be also mixed with regular diesel and reduce engine emissions ,or applied to the automotive and machinery. More importantly, biodiesel is a reliable alternative to fossil diesel. The national biodiesel standards are not perfect，and the study on the quality factors of biodiese is seldom, so it is necessary to strengthen quality factors analysis and countermeasures of biodiesel. In this thesis, SCI, CNKI, Google academic search instruments are used to research physical indicators of biodiesel at home and abroad, and to study their impact on the quality of biodiesel, further explore the relationship between physical and chemical indicators of biodiesel and the environment, the diesel engine. Compare and analyse the advantages and disadvantages of each method and application situation to propose the optimal detection method. Finally, the improving standard of biodiesel can be expected and discusse . The studied results show that methanol, ash, glycerides, fatty acids, naphthenic acids and other ingredients in biodiesel can affect the normal operation of the engine. Methods to detect these harmful components have their own advantages, and infrared spectroscopy with low cost, rapid detection, a sample can measure a number of physical and chemical indicators of a single sample simultaneously, which make it the best for the current detection methods.
