In today's world, plastics are the most indispensable material and their use in automobiles are increasing day by day. Many vehicles are scrapped year by year, from which plastic waste can be converted as usable fuel. This paper deals with analyzing the performance of diesel like fuel obtained by pyrolysis process from bumper waste and to study its emission and combustion behavior by using it in a compression ignition (CI) engine. For extraction, pyrolysis process was adopted and temperature was maintained at 240–360 °C. Fuel property testing was done on the resultant oil collected. It was then blended with diesel in the proportions of WBO P20, WBO P30, WBO P60, and WBO P80 with diesel and tested in a CI engine and its results analyzed. The results show WBO P20 is better with 31.43% BTE, 0.153% of CO emission, 1595 ppm of NO emission, 65.7% of smoke emission and 118 ppm of HC emissions slightly higher than diesel. The cylinder peak pressure for WBO P20 was found to be 71.08 bar and peak heat release was found to be 45.93 J/deg CA which matches diesel combustion. © 2022 Elsevier Ltdeninfo:eu-repo/semantics/closedAccessAnd Waste to EnergyAutomotive Bumper PolywasteCombustionDiesel EngineExhaust EmissionPerformanceWaste Bumper OilArticle318WOS:0008206132000032-s2.0-85125772680Q110.1016/j.fuel.2022.123559Q1
