An Experimental Study on Emission Characteristics of Exhaust Gas for Diesel Engines

In this study, for the purpose of collecting data of combustion conditions, experimental apparatus was set up. Experimental divices consisted of pressure data acquisition system in cylinder, measuring system of specific fuel consumption and power, detection system of the crank angle and analysis system of exhaust gas, etc.. Influences of pressure data acquisition hole and speed of the revolution were investigated to detect TDC. Pressure fluctuation rate, heat release rate, heat loss rate and variation of combustion gas temperature, etc.. from cylinder pressure data were calculated to analyze of combustion conditions. The characteristics on NOx, CO emission by variations of load Engine speed and cooling water temperature were investigated.
