摘　　要：国内对压缩比法测量柴油十六烷值方法研究较少,而该方法是在柴油评定出现纠纷之后唯一的仲裁方法。应用该方法设计的柴油十六烷值测定机市场基本被美国WAUKESHA公司所占有,为实现柴油十六烷值测定机国产化,对柴油十六烷值测定机进行了研究。经过对柴油从建压、喷射到压燃过程的时序分析,设计柴油十六烷值测定机电控喷油系统、喷油爆震信号检测装置以及试验工况检测装置。通过对不同油品的多次评定以及与进口仪器的多次数据对比,试验结果表明,仪器的重复性和再现性均满足标准要求。同时,在手轮数据读取、喷油角度调整、流量测量方面实现自动化,在数据管理方面实现与中石化、质检所等单位实验室管理系统(LIMS)对接。There are few researches on the compression ratio method to measure cetane number of diesel oil in China,and this method is the only arbitration method after the dispute of diesel oil evaluation.The market of Diesel Cetane Number measuring engine designed by this method is basically occupied by Waukesha company.In order to realize the localization of Diesel Cetane Number measuring engine,the Diesel Cetane Number measuring engine was studied.After analyzing the time sequence of diesel from pressure build-up,injection to compression ignition,the electro-mechanical control injection system for Diesel Cetane Number measurement,the detection device of injection knock signal and the detection device of test condition are designed.Through multiple evaluations of different oil sample and multiple data comparison with imported instruments,the test results show that the repeatability and reproducibility of the instrument meet the standard requirements.At the same time,the automation of handwheel data reading,fuel injection angle adjustment and flow measurement is realized,and the data management is connected with the laboratory management system(LIMS)of Sinopec and quality inspection institute.
