Abstract A physics based one-dimensional transient seven partial differential equation model is proposed to study the oxygen storage dynamics and cold start behavior of a three-way catalytic converter. The model uses the recently published simplified kinetic model, is computationally efficient and may be used for offline TWC outer loop controller design and validation. The proposed TWC model is validated using emissions data collected in a vehicle over multiple drive cycles including FTP cycles....

Abstract We propose a low-dimensional model of the three-way catalytic converter (TWC) that would be appropriate for real-time fueling control and TWC diagnostics in automotive applications. The model reduction is achieved by approximating the transverse gradients using multiple concentration modes and the concepts of internal and external mass transfer coefficients, spatial averaging over the axial length and simplified chemistry by lumping the oxidants and the reductants. The reduced order mod...

A four-mode low-dimensional model for the in-cylinder combustion process in an internal combustion engine is developed. The lumped parameter ordinary differential equation model is based on two mixing times that capture the reactant mixing limitations inside the cylinder and mixing limitations caused by the input and exit stream distribution. For a given inlet and operating conditions, the model predicts the exhaust composition of regulated gases (total unburned HCs, CO, and NOx) as well as the ...

Abstract Nanocrystalline tin oxide (SnO 2 ) thin films of 200 nm thickness were deposited on quartz and sapphire substrates by e-beam evaporation method. The substrate temperature was kept at 200 °C to enhance the surface diffusion of the atoms. The films were characterized by atomic force microscopy (AFM), glancing angle X-ray diffraction (GAXRD) and UV-visible spectroscopy for morphological, structural and optical characterization respectively. The nanocrystalline grains are found to be 4 ± 2 ...
