Diesel engines have been used in a wide variety of commercial vehicles. However, several problems must be solved. One of the major concerns is that diesel exhaust gas has more particulate matters (PM) including soot, which are suspected to be linked to human carcinogen. Then, more strict diesel emissions standards are being set in many counties. Recently, in order to reduce PM in the after-treatment of exhaust gas, DEGPBS (diesel exhaust gas perfect burning system) has been developed by COTEC Company, Ltd. In this study, we conducted numerical simulation of soot combustion in DEGPBS by the Lattice Boltzmann method. The inner structure of the filter was obtained by a 3D X-ray CT technique. Results show that the combustion reaction is well simulated to discuss the burning rate of soot particles in exhaust gas.
