Refining and Reuse of Waste Lube Oil in SI Engines: A Novel Approach for a Sustainable Environment

The protection of the environment and pollution control are issues paramount importance. Researchers today engrossed in mitigating harmful impacts petroleum waste on environment. Lubricating oils, which essential for smooth operation engines, often disposed improperly after completing their life. In experimental work presented this paper, deteriorated engine oil was regenerated using acid treatment method reused engine. comparison properties oil, engine’s performance, emissions from presented. reuse evaluation establish usefulness regeneration lubricating oil. For used total number (TAN), specific gravity, flash point, ash content, kinematic viscosity changed by 60.7%, 6.7%, 4.4%, 96%, 15.5%, respectively, compared with fresh partially restored all lost properties. performance parameters, brake power (BP), fuel consumption (BSFC), exhaust gas temperature (EGT) improved use CO NOX contents acid-treated were 9.7% 17.3% less respectively. Thus, showed along significantly reduced when employed an SI
