Estimation of Diesel Soot Particles in Exhaust Gas Emission and Its Accumulation in Diesel Particulate Filter Using Graphical Calculation Model 2021-26-0195
To avoid frequent regeneration intervals leading to expeditious ageing of the catalyst and substantial fuel penalty for the owner, it is always desired to estimate the soot coming from diesel exhaust emission, the soot accumulated and burnt in the Diesel Particulate Filter (DPF). Certain applications and vehicle duty cycles cannot make use of the differential pressure sensor for estimating the soot loading in the DPF because of the limitations of the sensor tolerance and measurement accuracy. The physical soot model is always active and hence a precise and more accurate model is preferred to calibrate & optimize the regeneration interval. This paper presents the approach to estimate the engine-out soot and the accumulated soot in the DPF using a graphical calculation tool (AVL Concerto CalcGraf™). The tool reduces the efforts of driving different duty cycles multiple times on the testbed and recurrent vehicle trips for data collection while calibrating the soot models, hence saving testbed cost, diesel cost, and manpower efforts. Results were established over BSVI emission legislative cycles (WHTC) and vehicle duty cycles to ratify with the model-generated data.
