Authors Abstract
Content
Catalytic converter substrates for automobile emission control have to operate under the hostile conditions of the automotive exhaust.
This paper will first discuss the mechanical and physical properties to ensure durable mechanical function of the catalytic substrate and converter system.
High temperature mechanical and thermal shock substrate requirements and properties will be discussed.
The functionality of a catalytic converter is significantly influenced by the catalytic coating. At the same time, substrate characteristics as will be shown, also effect converter functional parameters like back pressure, light-off and conversion efficiency. The importance of the substrate parameters cell shape, cell density and substrate mass and their effect on thermohydraulic parameters like heat- and mass transfer factors for various cell structures and substrates will be presented.
