The combustion characteristics of single cylinder DI diesel engine while diethyl ether injected into the inlet manifold at various proportions with the optimum percentage of ethanol blended diesel are experimentally investigated in the present study. Test fuel for secondary injection is diethyl ether and pilot fuel for test rig is E15 (15% bio ethanol blended with 85% diesel). The injected diethyl ether percentage into inlet manifold varied from 0 to 30.The injection of diethyl ether into inlet manifold is done by using low pressure injector. The increase in injection percentages of diethyl ether into the inlet manifold raises maximum heat release rate and cylinder pressure of the combustion chamber. Maximum heat release rate increases by 13% for 30 percentage injection of diethyl ether. The cylinder pressure increased by 3 bar while compare with pure diesel.
