乳化油对内燃机的燃烧特性和污染有显著的改善效果，但也明显延长了着火时间。针对这一问题，从实验与计算两方面综合分析了易燃添加剂在不同因素如环境温度和压力、添加剂的挥发性(包括沸点与蒸发潜热)等对着火延迟的影响，以寻求克服水分对燃烧的不利影响，得出一些规律性的结论，如通过提高压力与温度等可以显著地改善燃烧。

The water in emulsified oil plays an important role in reducing the pollutants and improving combustion efficiency in diesel,but it also causes difficulties to ignition on the other hand.As for this problem,this paper analyzes the effects of flammable additives on the ignition delay time under a normal pressure from experiment,and the discussions about different conditions such as changing temperature and pressure.The results show that as the addition of flammable additive can affect the ignition characteristics of emulsified oil and enhance environment temperature and pressure.Therefore,it is a useful and practical method.
