Depletion of fossil fuels and stringent emission norms focus attention to discover an evitable source of alternative fuel in order to attribute a significant compensation on conventional fuels. Besides, waste management policies encourage the valorization of different wastes for the production of alternative fuels in order to reduce the challenges of waste management. In this context, pyrolysis has become an emerging trend to convert different wastes into alternate fuel and suitable to be used as a substitute fuel for CI engines. The current investigation provides a sustainable and feasible solution for waste plastic management by widening the gap between global plastic production and plastic waste generation. It investigates the performance and emission of a single cylinder DI four stroke diesel engine using waste plastic oil (WPO) derived from pyrolysis of waste plastics using Zeolite-A as catalyst. Engine load tests have been conducted taking waste plastic oil and subsequently a blend of waste plastic oil by 10%, 20%, and 30% in volume proportions with diesel as fuel. The performance of the test engine in terms of brake thermal efficiency is found marginally higher and brake specific fuel consumption comparatively lowest for 20% WPO-diesel blend than pure diesel. The NOx and HC emission is found lower under low load condition and became higher by increasing the load as compared to diesel. Fuel exergy was significantly increasing after blending of WPO with pure diesel, but exergetic efficiency of the blended fuels followed the reverse trend. However, increase in load of the engine improved the exergetic efficiency. The 20% WPO–diesel blended fuel is found suitable to be used as an alternative fuel for diesel engine.

化石燃料的枯竭和严格的排放规范将注意力集中在发现不可避免的替代燃料来源上，以便对传统燃料进行重大补偿。此外，废物管理政策鼓励为生产替代燃料而对各种废物进行定值，以减少废物管理的挑战。在这种情况下，热解已成为将不同的废物转化为替代燃料的一种新兴趋势，并且适合用作CI发动机的替代燃料。当前的调查通过扩大全球塑料生产与塑料废料产生之间的差距，为废塑料管理提供了一种可持续可行的解决方案。它研究了使用废塑料油（WPO）的单缸DI四冲程柴油机的性能和排放，该废塑料油是通过使用Zeolite-A作为催化剂热解废塑料而得到的。已经对废塑料油进行了发动机负载测试，随后以10％，20％和30％的体积比将废塑料油与柴油作为燃料进行了混合。与纯柴油相比，发现20％WPO-柴油混合物的试验发动机在制动热效率方面的性能略高，制动比燃油消耗相对最低。与柴油相比，在低负荷条件下发现NOx和HC排放较低，并且通过增加负荷而变得较高。WPO与纯柴油混合后，燃料的火用显着增加，但是混合燃料的高能效遵循相反的趋势。然而，发动机负荷的增加提高了动力效率。已发现20％的WPO-柴油混合燃料适合用作柴油发动机的替代燃料。
