ABSTRACT:
A method is provided for assembling a plurality of catalytic substrates and support materials within a catalytic converter housing using a uniform compression. Outer profiles of a plurality of catalytic substrates are determined. Weight factors of a plurality of the support materials are determined. A lookup table containing a list of associated outer profiles of catalytic substrates and weight factors of support materials are provided. A first catalytic substrate and a first support material are joined as a first pre-assembly based on a matching outer profile and weight factor from the lookup table. A second catalytic substrate and a second support material are joined as a second pre-assembly based on a matching outer profile and weight factor from the lookup table. The first and second pre-assemblies are inserted into the catalytic converter housing. The first catalytic element and the second catalytic element are secured within the catalytic converter housing.
