RÉSUMÉ

Investigation of a charged agglomerator and a diesel particulate filter setup is carried out. To analyze the economical efficiency and emission performance of the diesel engine, bench testing was conducted on the coupled setup (i.e., engine, charged agglomerator, and a diesel particulate filter). After running the engine for 3000 s, the pressure drops and fuel consumption decreases by 0.3 kPa and 2%, respectively. Smoke intensity decreases significantly under a high engine load, while filtering efficiency also increases by 3.1%. The particles microstructure and morphology were obtained with the aid of a transmission electron microscopy (TEM). The accumulation and overlap phenomenon of particles increases intensely after going through the charged agglomerator. After passing through the filter, small clusters of particles are distributed, with a clearer outline and improved degree of graphitization. Based on the "box counting method", the fractal dimensions of the particles were analyzed. The fractal dimensions increase after going through the charged agglomerator but decrease after passing through the filter, confirming the results obtained from the TEM.
