ABSTRACT:
A catalytic converter includes a casing tube having a given internal diameter. At least two individual honeycomb bodies through which a fluid can flow in a given flow direction, are disposed in the casing tube. The honeycomb bodies are formed of structured metal layers forming flow channels. The layers are joined to the casing tube by joining techniques, such as hard brazing. The honeycomb bodies have a given theoretical strain-free diameter and have an internal layout making the honeycomb bodies elastic and permitting the honeycomb bodies to be inserted into the casing tube with an elastic compression of from 2 to 10% of the given theoretical strain-free diameter and with prestress. A method for producing a catalytic converter includes forming at least two honeycomb bodies with a given theoretical strain-free diameter from structured metal layers defining channels through which a fluid can flow in a given direction. The honeycomb bodies are subsequently successively or simultaneously inserted with prestress from at least one side into a prefabricated casing tube having a given internal diameter. The honeycomb bodies are elastically compressed by from 2 to 10% of the given theoretical strain-free diameter and/or at least partial regions of the casing tube are subsequently plastically compressed by from 2 to 10% of the given internal diameter. The layers are joined to the casing tube.
