摘要
采用热分析法研究了柴油机工作过程中内碳基微粒的氧化温度、最大氧化速率温度和燃烧结束温度等氧化特性。通过非等温法对腔内不同时间段的碳基微粒取样,研究其化学反应动力学参数的变化特性,并分析共轨压力、发动机转速、柴油机腔内的燃空当量比等因素对其产生的影响。
Some oxidation characteristics of carbon-based particles such as oxidation temperature,maximum oxidation rate temperature and combustion end temperature in the diesel engine during the work are studied.With non-isothermal method,carbon based particles are sampled at different times to study its properties of chemical reaction kinetic parameters.The influences of conjugated pressure,engine speed and ratio of internal combustion air to volume are analyzed.
