Depletion of fossil fuels and environmental pollution has led researchers to foresee the need to develop bio-fuels. Alcohols are a major part of bio-fuels. This study debates combustion performance and exhaust emissions from CI engine fuelled with diesel-ethanol blends. The fuel blends contained % 100 diesel (E0), % 90 diesel - % 10 ethanol (E10) and % 80 diesel - % 20 (E20) ethanol by volume. Tests were conducted at %0, %25, %50, %75 and %100 load conditions at various ethanol mass. The effects of blended fuels on engine performance were investigated and results showed that E10 presents the highest volumetric efficiency; on the other hand E20 showed the lowest volumetric efficiency. Maximum in-cylinder pressure was occured conventional diesel combustion. Results indicated that the concentrations of CO2 and HC (unburnt hydrocarbons) emissions weren't significant difference. E10 presented the lowest CO emission at all engine loads. In addition to this NO emission was peaked on E20 at %75 load.
