Tests have been carried out to evaluate the performance, emission, and combustion characteristics of a single cylinder direct injection diesel engine fueled with 10%, 30%, and 50% of tyre pyrolysis oil (TPO) blended with diesel fuel (DF). The TPO was derived from waste automobile tyres through vacuum pyrolysis. The combustion parameters such as heat release rate, cylinder peak pressure, and maximum rate of pressure rise also analysed. Results showed that the brake thermal efficiency of the engine fueled with TPO-DF blends increased with an increase in blend concentration and reduction of DF concentration. NO(x), HC, CO, and smoke emissions were found to be higher at higher loads due to the high aromatic content and longer ignition delay. The cylinder peak pressure increased from 71 bars to 74 bars. The ignition delays were longer than with DF. It is concluded that it is possible to use tyre pyrolysis oil in diesel engines as an alternate fuel in the future.
已开展试验，以评估一台单缸直喷式柴油发动机使用与柴油（DF）混合10%、30%和50%的轮胎热解油（TPO）时的性能、排放和燃烧特性。TPO是通过真空热解从废旧汽车轮胎中获得的。还分析了燃烧参数，如热释放率、气缸峰值压力和最大压力上升率。结果表明，使用TPO-DF混合燃料的发动机的制动热效率随着混合浓度的增加和DF浓度的降低而提高。由于高芳烃含量和较长的点火延迟，在高负荷下发现NO(x)、HC、CO和烟雾排放更高。气缸峰值压力从71巴增加到74巴。点火延迟比使用DF时更长。得出的结论是，未来有可能在柴油发动机中使用轮胎热解油作为替代燃料。
