燃料添加剂改善燃料均质自燃着火的研究

Research on Fuel Additives Improving Fuel Homogeneous Auto-Ignition

应用质谱检测器研究了燃油(含过氧化物添加剂)均相受热燃烧(分解)行为．实验结果表明,过氧化物类添加剂能有效改善燃料着火能力,添加剂起作用的有效温度范围为500～900 K．质谱检测结果与发动机实验结果有很好的一致性,表明设计的实验是研究和筛选HCCI燃料添加剂的一个简便可靠的方法,为今后这一领域的研究提供了一个快速和有力的工具．

Homogeneous combustion/decomposition of fuel with peroxide additives added was investigated based on mass spectrographic detector. The experimental results show that fuel ignition is effectively improved by peroxide additives. The available temperature range for fuel additive to improve the ignition is 500--900 K. The laboratory results well agree with the engine test, which indicates that this approach is simple and reliable for screening HCCI additives, providing a rapid and highly effective tool for the future research in this field.
