Recently, increasing usage of the diesel vehicle because of high efficiency and power, many countries try to reduce the exhaust gas emissions. So, effects of the fuel composition were investigated by using additive fuels in diesel engine.<br/> Exhaust emissions were measured with increasing RPM and LOAD by using the oxygenated fuel A and B in a 4-cylinder, EDI diesel engine. Oxygenated fuel A is including oxygen of 53% in itself. The oxygen content influenced the combustion process strong. So, smoke emissions were lower than those of diesel fuel. Especially, when the amount of oxygenated fuel A was 10%, the smoke emission was significantly reduced in high speed and load. CO emissions did not show a characteristic inclination, but considerably reduced in high load. And in high load were NOx emissions reduced, but in low and mid load were not.<br/> When oxygenated fuel B was used, Smoke and CO emissions increased but NOx emissions reduced than these of diesel fuel. The exhaust gas emission was greatly influenced by the changing of fuel composition in the 4-cylinder, conventional diesel engine using additive fuels.<br/>
