Abstract
This study presents the effect of ‘diethyl ether’ on irreversibilities, which are based on exergy evaluation and emission of waste cooking oil methyl ester fueled “direct-injection-diesel engine.” Testing was conducted on unit cylinder engine, for various load levels (20%, 40%, 60%, 80%, and 100%) with speed rate of 1600 rev/min. It is found that DEE significantly could be relevant in reducing NOx emission, irreversibilities and improve exergetic efficiency. For 15% DEE mixing, thermal efficiency is improved from 25.15 to 35.12% at full load; however, the second law efficiency or exergetic efficiency is enhanced from 13.12 to 28.25%. It is found that diethyl ether could reduce smoke opacity effectively. The sustainability index presented that the blending of diethyl ether with waste cooking oil methyl ester could substitute for mineral diesel.
