A method of manufacturing an oval shaped catalytic converter that reduces the amount of material and number of parts that are required for permitting the catalytic converter to treat the exhaust gases of an internal combustion engine and also improves the structural durability of the converter for h

대표청구항 ▼

[ We claim:] [1.] A method of manufacturing a catalytic converter structure for the treatment of the exhaust gases of an internal combustion engine and which includes a housing having an oval-shaped catalyst coated substrate mounted therein with its outer surface provided with a sheet of flexible material, said method comprising the steps of:forming a sheet of metal into an oval-shaped housing that terminates at each end with an oval-shaped peripheral edge defining an oval opening located in a plane extending transversely to the longitudinal center axis of said housing and dimensioned so when said substrate alone is centrally located within said oval opening the gap between the inside surface of said housing and the outside surface of said substrate along the minor axis of said oval opening is less than the gap between the inside surface of said housing and the outside surface of said substrate along the major axis of said oval opening,applying a force to said housing so that the inside surfaces of said housing along said minor axis increase in distance and cause the inside surfaces of said housing along said major axis to decrease in distance so as to provide a temporarily deformed oval cavity within said housing,placing said sheet of flexible material on the body of said substrate to cover the latter and provide a substrate-flexible material assembly,inserting said substrate-flexible material assembly into said deformed oval cavity within said housing,relieving said force so as to cause said inside surfaces of said housing along said minor axis and along said major axis to spring back toward their original positions and provide a desired pressure to said sheet of flexible material along said minor axis and said major axis, andsecuring an end member to said oval-shaped peripheral edge at each end of said housing whereby said desired pressure along said minor axis and said major axis is maintained.
