Performance Evaluation of Diesel Engine using Fuel Oil Produced from Plastic Waste

Recently, the pyrolysis is proposed for plastic waste management. It efficiently converts plastic waste into fuel oil. In this paper, the fuel properties of fuel oil, diesel-fuel oil blends, and their performance in the diesel engine are presented and discussed. The most of the fuel properties of fuel oil produced from plastic wastes were on par with diesel fuel. Diesel engine testing unit (3.7 kW, single-cylinder) was used to study the engine performance and emissions during the use of plastic waste derived fuel oil and their blends. The results found that the brake-specific fuel consumption of engine operated with fuel oil and diesel at full load conditions was 294 and 276 g/ kWh, respectively. The brake thermal efficiency for the engine testing at full load with fuel oil and diesel was found to be 27.50 and 28.08 %. The maximum exhaust gas temperature recorded for full load condition was 452ºC for fuel oil, whereas it was 418ºC for diesel fuel. At full load conditions, the recorded higher carbon dioxide emission was 7.84 % for fuel oil and 6.92% for diesel fuel. The observed higher carbon monoxide emission was 0.142 % for fuel oil alone, whereas that of diesel fuel was 0.081% at full load condition. Maximum NOx emission at full load condition was measured as 905 ppm for fuel oil alone, whereas that of diesel fuel was 861 ppm.
