Abstract: 
In dual fuel engines, pilot fuel quantity has significant effects on performance and emissions. To investigate combustion. performance and emissions of these engines at different loads, experimental studies have been carried out on a dual fuel engine.
In this work. ignition delay, combustion process and pollutant formation were analyzed in two ways. In the first method, amount of the pilot fuel was kept constant. while gaseous fuel quantity and the engine load were increasing. In the second method, for 25% load by decreasing pilot fuel, more gaseous fuel was substituted. The results indicate that at full load condition, increasing gaseous fuel and decreasing pilot fuel quantities. decrease combustion duration and concentration of CO, TUHC pollutants. But at part load (25%), increasing gaseous fuel and decreasing pilot fuel, increase combustion process duration, concentration of CO, TUHC pollutants increase and at last, performance parameters deteriorate.
