Effects of injection timing on the performance and emissions of a diesel engine fuelled with diethyl ether blended thevetia peruviana biodiesel
Fast depletion of petroleum reserves and existing emission norms drive us to search for the apt fuel for the IC engines. Biodiesel derived from vegetable oils is being tried now–a–days in most of the researches. A number of researches are in progress to reduce the emissions by using various techniques. In this study, the injection timing of a single cylinder diesel engine is advanced from 23° to 27° and the effects on performance and emissions of diesel engine is studied in both part load and full load. Thevetia peruviana biodiesel is blended with diethyl ether (DEE) in the ratio of 5%, 10%, 15%, and 20% and used as fuel. This study reveals that 20% DEE blend shows a better combination than that of biodiesel among the blends. It is also observed that the advancing of injection timing results in better performance and less emission than that of original injection timing both in part load and full load.
