Microscopy investigations of ash and particulate matter accumulation in diesel particulate filter surface pores
… ash interactions with DPF walls, pores, and the catalyst washcoat. Based on scanning electron microscopy analysis of ash loaded DPFs from the field and from filters loaded with ash in the laboratory, a mechanism for ash accumulation is presented.

Evaluation of advanced air-fuel ratio control strategies and their effects on three-way catalysts in a stoichiometric, spark ignited, natural gas engine
… to decrease further in the future. A three-way catalyst (TWC) is a cost-effective exhaust after treatment system can be used to reduce pollutant emissions through a series of reactions that are catalyzed by special conditions within the catalyst. Using TWCs, emissions can be drastically reduced …

Multiscale computational simulation of multidimensional chemically reacting flow over washcoated heterogeneous catalysts
… CFD models; and the development of catalytic washcoat performance relations informed by 3D reconstructions of actual, commercial washcoats. Ceramic microchannel heat exchangers/reactors have several distinct advantages. They are cost effective, chemically inert, are capable of operating at …
