ABSTRACT
This research aims to optimize combustion by using alternate fuel sources. It also studies biodiesel with an ignition improver blend at an increased compression ratio of 20 by supplying ethanol with preheated air. In order to obtain baseline data, the research process was first carried out with diesel. It was then analyzed using the blend of diesel, Prosopis juliflora methyl ester as biodiesel, and an ignition improver (di-ethylether) in the same conventional mode. This blend, known as B30DEE1, is composed of 30% biodiesel, 69% diesel, and 1% di-ethylether by volume. The experiment was repeated by using combustible mixture B30DEE1+ETH, which contains biodiesel 30%, diesel 69%, di-ethylether 1% and ethanol 10% on a volume basis. The ethanol mists were added by port injection in the proportion of 10% into the preheated air stream to attain partially premixed condition for reactivity controlled combustion. The elevated brake thermal efficiency and reduced HC and CO concentrations were recorded along with the increased heat release rate at reactivity controlled compression ignition (RCCI) mode.
