A set of accurate estimate model and computer algorithm for installing in a control module of diesel engine exhaust is developed based on the data of differential pressure sensors and particulate matters. In the estimate model, the pressure drop vs. particulate matter loading relations are described for three different phases. Through a detailed examination of the original equations and its comparison with the experimental data, a simplified model equation is derived. The equation is that ΔP=C1Q + C2Q2, where ΔP : total pressure drop, Q : volume flow rate, C1 and C2 :coefficients. The accuracy is confirmed by vehicle tests of European and North American driving cycle modes. The evaluated error is much less than the required tolerance of 0.5g/L.
