Today, there is an effort to obtain energy from every possible source and waste to meet the oil demand. Waste engine oil is one of them. Although waste lubricating oils have an important economic potential, the environmental effect of these oils is much more important than their economic effect. In this study, various waste engine oil‐diesel mixture (0:100, 10:90, 20:80, and 30:70) and various fuel pressure conditions (195–255 bar) experiments were performed for various engine loads (3–12 Nm) in a DI diesel power generator. It was aimed to increase the potential of using waste engine oil as fuel by adding 16 μmol/L Mn additive to the waste engine oil. For the design of the experiment, 1/8 fractional factorial Taguchi method was applied and the relationship between engine load, waste engine oil, fuel injection pressure and Mn additive with experimental factors has been successfully determined with variance analysis. Using regression analysis, regression equations were obtained for exhaust temperature, specific fuel consumption, light absorption coefficient, and nitrogen oxides. Finally, although waste engine oil causes deterioration on engine performance and emissions, it has been determined that the use of waste engine oil as fuel can be improved thanks to the Mn additive.

在柴油发电机中使用锰添加剂改良的废机油作为燃料的实验研究

如今，人们正在努力从各种可能的来源和废物中获取能量，以满足石油需求。废机油是其中之一。尽管废润滑油具有重要的经济潜力，但这些油的环境影响远比其经济影响重要。在这项研究中，针对各种发动机负荷（3 – DI柴油发电机中的最大功率为12 Nm）。目的是通过向废机油中添加16μmol/ L Mn添加剂来增加使用废机油作为燃料的潜力。在实验设计中，采用了1/8分数阶分数阶Taguchi方法，并且研究了发动机负载，废机油，通过方差分析已成功确定了燃料喷射压力和Mn添加剂以及实验因素。使用回归分析，获得了排气温度，比燃料消耗，光吸收系数和氮氧化物的回归方程。最后，尽管废机油引起发动机性能和排放的恶化，但是已经确定由于使用了Mn添加剂，可以改善废机油作为燃料的使用。
