Abstract: Biofuels are popular as renewable, sustainable, and alternative fuel sources for compression ignition engines. This is because they reduce dependence on imported petroleum, combat global warming, and extend engine life amid environmental degradation and rising oil prices. Biofuels cause long-term issues for compression ignition engines, such as injector coking, ring-sticking, poor atomisation, deposits, injector pump faults, and lubricating oil dilution via crank case polymerisation. This article assessed the wear impact of waste plastic oil (WPO) on engine components and compared it to conventional diesel fuels to determine its viability as a long-term fuel option for compression ignition engines. A diesel engine was subjected to a 512-hour endurance test using diesel fuel and WPO, and its physical condition, dimensions, and weight were analysed before and after the test. WPO-fuelled engines showed reduced wear on several components, including piston rings, piston, gudgeon pin, cylinder liner, bearing, and valves.

Keywords: biofuels; WPO; diesel engine; long run endurance test; wear.
