In this paper, response surface method (RSM) was proposed to determine fuel flow performance of an internal combustion diesel engine by using different specific conditions (injection pressure, engine speed and throttle position). Injection pressure of the diesel engine was chosen as 150 bars for turbocharger and pre-combustion chamber. Experiments were realized at four pressures corresponding to 100, 150, 200 and 250 bars each with throttle positions of 50, 75 and 100%. A mathematical model was used to predict fuel flow performance of engine according to pressures and throttle positions. The optimum performance conditions, for a required fuel flow, were obtained by using response surface method with 3D graphics. The developed prediction equations showed that the linear effect of engine speeds was the most important factor that influenced the fuel flow. Moreover, whether the proposed mathematical model of fuel flow is within the limits of the performance parameters has been considered.
