    Abstract：Around the aspects of measuring method of unregulated emissions produced by biodiesel. According to the physical and chemical characteristics of the carbonyl and aromatic hydrocarbons, chooses appropriate sampling method, sample pretreatment method and Sample separation and determination method, adopts derivatization method and high performance liquid chromatography(HPLC) method to measure carbonyl, uses activated carbon adsorption tube and Gas chromatography /mass spectrometry to Qualitatively and quantitatively analyze aromatic hydrocarbons, it proves that the Relative standard deviation (RSD) and recovery rate can meet the measurement requirements, so that can realize the rapid and accurate measurement of carbonyl and aromatic hydrocarbons of diesel engine. Collecting the lubricating oil samples of different running time, adopting Scanning electron microscope (SEM) and X-ray spectroscopy, the changes of lubricant oil absorbance was measured, the type and quantity of metal elements were investigated, and the source of metal particle and the influence on the quality of total particles were discussed.
