Usage of oxygenated fuels either as replacement to fossil fuels or as additives to fossil fuels and alternative fuels is given much interest. Diethyl Carbonate (DEC) is an oxygenated additive which is non-toxic in nature and biodegradable as well. The objective of this study is to replace utilization of diesel fuel on diesel engine by 50 vol% with Waste Plastic Oil (WPO). This study also analyses the effect of addition of DEC in proportions of 5, 10 and 15 vol% to WPO on performance and emission of a diesel engine. Test fuels D50WPO50 (50% diesel + 50% WPO), D50WPO45DEC5 (50% diesel + 45% WPO + 5% DEC), D50WPO40DEC10 (50% diesel + 40% WPO + 10% DEC) and D50WPO35DEC15 (50% diesel + 35% WPO + 15% DEC) were prepared. Tests were conducted on a single cylinder diesel engine at 20%, 40%, 60%, 80% and 100% load. The results of performance and emission characteristics of test fuels were compared with diesel fuel. Test results show that the spray effect of DEC has increased brake thermal efficiency and reduced brake specific fuel consumption. Addition of DEC to WPO-diesel blends not only optimize the burning process but also minimize engine exhaust emissions. The problems of fuel energy crisis and plastic waste management can be addressed simultaneously with production and utilization of fuel produced from plastic wastes.
