초록	Low temperature combustion regime for the simultaneous reduction of nitrogen oxides (NO_x) and paticulate matter (PM) is demonstrated in single cylinder engine at various operating parameters, such as EGR rate, injection timing, EGR temperature, amount of fuel and swirl rate. Low temperature combustion is accomplished by high exhaust gas recirculation (EGR) rate in this study. Generally, the emission of NO_x almost completely disappears and PM significantly increases in the first decreasing regime of oxygen concentration but after peaking about 10-12% oxygen concentration, PM then decreases regardless of fuel injection quantity. Low temperature combustion regime was extended by low EGR temperature, high injection pressure and low amount of fuel.
