Abstract

In this research, the effect of water content in a-zeotropic ethanol to the power produced, specific fuel consumption, and the thermal efficiency of an SI engine was observed. Tests carried out on anhydrous ethanol fuel (99.7% v) and a-zeotropic ethanol fuel (95.5% v). The test was carried out using the engine brake power indicator load cell type TD 800PM. The amount of power produced, specific fuel consumption and engine thermal efficiency were tested for varying load on four stroke one-cylinder engine. The amount of power, specific fuel consumption was observed, also the thermal efficiency produced by both of the fuels was calculated. The amount of power, specific fuel consumption and thermal efficiency using both types of fuel compared. The results showed that the amount of power produced by a-zeotropic ethanol fuel was higher than anhydrous ethanol fuel. The need for specific fuels when uses a-zeotropic ethanol slightly higher than anhydrous ethanol. Engine thermal efficiency produced by a-zeotropic ethanol is lower than anhydrous ethanol.
