Study on performance and emission characteristics of split injection CRDi engine fueled with orange peel oil and diethyl ether

Abstract

Abstract The constant increase in energy demand and the environmental issues due to higher utilisation of diesel fuel is frightening. The replacement of diesel fuel with biodiesel is the most viable solution to minimize the diesel fuel consumption and greenhouse gas emissions. The biodiesel with orange peel oil (OPO) and diethyl ether (DEE) can serve as a valuable alternative fuel, as OPO is naturally available with higher energy efficiency. The extracted orange peel oil characteristics gave its chemical and physical properties, which are suitable for using as additive for diesel fuel. The mixture is prepared with 30% DEE and 70 % of OPO to get B5 (950 ml Diesel + 35 ml OPO + 15 ml DEE) and B15 (850 ml Diesel + 105 ml OPO + 45 ml DEE) mixtures. In this study, a split injection CRDi engine is used to conduct performance and emission tests using the above three fuel options. The tests were conducted using the new blend for different engine operating conditions and the brake thermal efficiency of B5 mixture offers 0.6% to 2.3% higher values in comparison with diesel fuel.
