In this study, using droplet dripping and evaporation test rig, over ten thousands fuel droplets were dripped on a hot surface repeatedly, and evaporation deposits formed from them were quantitatively analyzed. Then, hot surface temperature and dripping interval were discussed with formation mechanism of evaporation deposits. Under various surface temperatures with fixed dripping intervals for diesel fuel test, developed test rig showed that it could be useful for simple evaluation method of evaporation deposits. Results show that wet-dry condition and hot surface temperature were main controlling factors of deposits development. Empirical equations of deposits development were derived from the experimental results. Further carbonaceous evaporation deposits from RME were around ten times serious than diesel fuel.

在这项研究中，使用液滴滴落和蒸发试验装置，将上万个燃料液滴反复滴在热表面上，并对它们形成的蒸发沉积物进行了定量分析。然后讨论了热表面温度和滴水间隔以及蒸发沉积物的形成机理。在不同表面温度下固定滴水间隔的柴油测试中，开发的测试装置表明它可用于蒸发沉积物的简单评估方法。结果表明，干湿条件和热面温度是矿床发育的主要控制因素。根据实验结果推导出矿床发育的经验方程。 RME 产生的碳质蒸发沉积物比柴油严重十倍左右。
