废润滑油是一种重要的能源类型。WLO不能直接在柴油发动机中燃烧，但可以加工成类柴油燃料（DLF）使用，以尽量减少其有害影响，最大限度地提高其有用价值。此外，WLO与柴油在理化性质上也存在一定的差异。为了研究两种燃料对柴油机燃烧和排放性能的影响，对未进行发动机改造的单缸直喷柴油机在4种发动机转速和5种发动机负荷下进行了台架试验。讨论了燃料对燃油经济性、燃烧特性以及碳氢化合物（HC）、一氧化碳（CO）、氮氧化物（NOx）和烟雾排放的影响。与柴油相比，DLF具有更长的点火延迟期和更短的燃烧持续时间。试验结果表明，DLF蒸馏温度的升高与燃烧压力、温度和放热速率的增加有关。在轻、中负荷下，DLF的制动比油耗（BSFC）在3000转时比柴油机降低了约3%。DLF在中等和重负荷下产生略高的氮氧化物排放，在中等负荷下产生更多的烟雾排放，并且在大多数测量点比柴油燃料产生更高的HC和CO排放。结果表明，DLF可作为高速柴油机的潜在可用燃料使用。
Waste lubricant oil (WLO) is one of the most important types of the energy sources. WLO cannot be burned directly in diesel engines, but can be processed to be used as diesel-like fuel (DLF) to minimize its harmful effect and maximize its useful values. Moreover, there are some differences in physicochemical properties between WLO and diesel fuel. In order to identify the differences in combustion and emission performance of diesel engine fueled with the two fuels, a bench test of a single-cylinder direct injection diesel engine without any engine modification was investigated at four engine speeds and five engine loads. The effects of the fuels on fuel economic performance, combustion characteristics, and emissions of hydrocarbons (HC), carbon monoxide (CO), nitrogen oxides (NOx) and smoke were discussed. The DLF exhibits longer ignition delay period and shorter combustion duration than diesel fuel. The test results indicate that the higher distillation temperatures of the DLF attribute to the increase of combustion pressure, temperature and heat release rate. The brake specific fuel consumption (BSFC) of the DLF compared to diesel is reduced by about 3% at 3000 rpm under light and medium loads. The DLF produces slightly higher NOx emissions at middle and heavy loads, somewhat more smoke emissions at middle loads, and notably higher HC and CO emissions at most measured points than diesel fuel. It is concluded that the DLF can be used as potential available fuel in high-speed diesel engines without any problems.
