通过基础油和加剂油实测放热规律的对比 ,就自行研制的c -RONO2 柴油十六烷值改进剂对柴油机着火和燃烧过程的影响进行了深入的分析。结果表明 ,十六烷值改进剂能加速柴油的氧化过程 ,缩短着火滞燃期 ,使预混合燃烧期和扩散燃烧期的放热百分比得到合理分配 ,从而改善了柴油机的着火和燃烧特性 Based on the comparison of the measured exothermic rule between base oil and additive oil, the influence of c -RONO2 diesel cetane improver on the ignition and combustion process of diesel engine was analyzed in depth. The results show that the cetane improver can accelerate the oxidation process of diesel fuel, shorten the ignition delay and make the heat release percentage of pre-mixing combustion and diffusion combustion reasonably distributed, so as to improve the ignition and combustion characteristics of diesel engine
