Effect of Soot Layer on Catalyzed Gasoline Particulate Filter（2nd report）
In the case of hybrid cars with both an internal combustion engine and a battery-powered electric motor, less space in the engine room is available. Then, one needs the aftertreatment system of a gasoline particulate filter (GPF) combined with a three-way catalyst (TWC). However, deposited soot inside the filter may degrade catalytic activity. In this study, by using a lattice Boltzmann method (LBM), the authors conducted numerical simulations of catalyzed GPF to discuss the effect of soot layer on the conversion rate of TWC. They investigated the effects of the deposited soot mass, the exhaust gas component and the filter length on the catalyst performance. Results show that as the deposited mass is increased, the conversion rates of CO, HC and NO are generally decreased. The concentrations of CO, HC and NO largely affect these conversion rates. When the filter length is larger, these conversion rates do not change much.
