Catalytic exhaust aftertreatment of vehicle engines is increasingly employed to the benefit of
the atmosphere quality, especially in the large urban area of the world. Both spark-ignition …

Monolith reactors have been widely used as catalytic converters in the automobile industry.
Their applications in other fields, such as environmental pollution abatement and …

The need for reliable 3-way catalytic converter modeling in the design of demanding
exhaust systems for low-emitting vehicles has been widely recognised. Although a number …

Catalytic converters with non-linear channel structures were prepared using 3D printing and
tested in the oxidation of methane in a simulated dual-fuel engine exhaust stream. The …

The diesel particulate filter (DPF) technology with the use of fuel additives as regeneration
aids is a promising technology for modern and future low-emissions diesel engines. The …

A numerical study of the interaction between flow, reactions and thermal effects in a planar
two dimensional model of a catalytic convertor is presented. A typical catalytic convertor …

The need for improved fuel economy, while meeting more stringent global vehicle emission
standards, continues to grow with the increasing demand for environmental protection and …

A multi-channel model is used to study the impact of flow non-uniformity during cold-start
transient operations of a catalytic converter. It is seen that inlet zone recirculation can lead to …

This work reports theoretical studies of flow behaviour in a monolith outlet zone for different
Reynolds numbers covering laminar and transitional/turbulent flow regimes. Monolith type …

A methodology is developed for analyzing the effect of non-uniform inlet flow distribution on
the conversion efficiency of an automotive catalytic converter. The flow through the converter …
