Thermal management plays a vital role in the modern vehicle design and delivery. It enables
the thermal analysis and optimisation of energy distribution to improve performance …

Internal combustion engines (ICE) still have potential for substantial improvements,
particularly with regard to fuel efficiency and environmental compatibility. In order to fully …

Mathematical modeling of three-way catalytic converter (3WCC) operation is increasingly
employed in automotive catalyst and converter systems optimization. Oxygen storage is …

Higher fuel economy and lower exhaust emissions for spark-ignition engines depend
significantly on precise air-fuel ratio (AFR) control. However, the presence of large time …

The paper presents a novel control-oriented, first-principle model of a three-way catalytic
converter (TWC). The model accurately predicts the air–fuel ratio downstream of the catalyst …

In this paper, a physics-based, oxygen storage-thermal model for a three way catalyst (TWC)
is developed and experimentally validated. This model is then extended to account for aging …

An increased concern about automotive pollution in the last 30 years has led to very
stringent emission standards. The subject of the research presented in this thesis was the …

It is a well-known phenomenon that the bulk of hydrocarbon emissions emitted from internal
combustion engines occurs during the coldstart period, thus necessitating new control …

Though very important for the system performance, the dynamic behavior of the catalytic
converter has mainly been neglected in the design of exhaust emission control systems …
