<span lang="EN-IN">Experimental investigation on the operational efficiency and emission characteristics of waste plastic oil - diesel fuel blends in a compression ignition engine

The study explores converting municipal plastic waste into oil via pyrolysis, blending it with diesel to create Waste Plastic Oil (WPO)-diesel blends (WPO۱۰, WPO۲۰, WPO۳۰, WPO۴۰) by varying the percentage volume of WPO. Experimental tests were performed on a single-cylinder stationary diesel engine, using WPO blends as fuel under loads ranging from no load to overloaded (۱۲۰%). Engine performance parameters, including brake thermal efficiency (BTE), brake specific fuel consumption (BSFC), carbon monoxide (CO), hydrocarbon (HC), nitrogen oxide (NOx), and smoke intensity, were measured using a high-speed data acquisition system and computer-interfaced setup. The engine achieved superior performance with WPO۲۰ (BTE: ۲۵.۸۶%, BSFC: ۰.۳۸ kg/kWh) compared to diesel (BTE: ۲۷.۰۱%, BSFC: ۰.۳۶ kg/kWh). WPO۱۰ demonstrated improved emissions, reducing HC by ۵.۷۱% and maintaining equivalent smoke levels compared to diesel. The study also examined the techno-economic implications of employing WPO in diesel engines.
