This study describes the influence of combustion parameters on the nitric oxide emission, such as injection timing, air flow rate, injected amount of fuel, and compression ratio of engine. In order to determine the influence factors on the nitric oxide emission, the experiment were investiwith various parameters of engine cycle. According to the results of this study, the retardaof injection timing and the increases of airflow rate, and the decreases of fuel injection amount reduce the nitric oxide concentration in the exhaust emissions. Also, the increases of comratio of engine increase in the concentration of nitric oxide formation in the combustion chamber. The results of this study give a guideline to decrease the nitric oxide formation by using the simulation program.<br/>

The purpose of this investigation is to carry out the effect of emulsified fuel on the combustion performance and exhaust emissions in direct injection type diesel engine. To control the emission in direct injection type diesel engine, the effect of emulsified fuel on the combustion and reduction of exhaust emissions was investigated by experiment.<br/> In this study, the experiment was conduct with a single cylinder diesel engine with the various water contents in the fuel. The results showed that the emulsified fuel results in the reduction of exhaust emissions and improve the engine performance in the engine. It found that emulsified fuel increased the cylinder pressure and the rate of heat release of engine.<br/>
