Abstract: PURPOSE:To obtain a catalytic converter which aims at reducing the flow resistance, by providing such an arrangement that a section which pierces through and extends in a converter casing has a cross-sectional area larger than that of a section which pierces through the converter casing. CONSTITUTION:A secondary air introduction pipe 11 attached to a converter casing 1, comprises a piercing section 12 piercing through a through-hole 3a formed in the lower half 3 of the converter casing 1 and an extending section disposed in a gap part 10 and extending in the direction crossing the stream of exhaust gas flowing in the gap, the extending section having a large pipe diameter or closs-sectional area in comparison with the piercing section 12. With this arrangement, the supply amount of secondary air is increased, particularly, due to the pulsation of exhaust gas.

Abstract: PURPOSE:To install a sealing member with ease in a catalytic converter, by packing a sealing member with a combustible film after compressing the sealing member, winding the packed sealing member around a monolithic catalyst carrier, installing the same in the casing of the catalytic converter, and then expanding the sealing member by burning out the combustible film. CONSTITUTION:In manufacturing a catalytic converter, a sealing member 4 made of a fiber material and having a thickness greater than the clearance delta between a casing 1 and a monolithic catalyst carrier 2 is prepared at first and it is compressed to such an extent that the thickness is made smaller than the clearances delta. Then, the sealing member 4 is inserted into a combustible film 5 and an enclosed sheet 6 of the combustible film is formed by evacuating the inside of the combustible film 5 and isolating the sealing member 4 from the atmosphere. Subsequently, the sheet 6 is wound around said carrier 2, and then the carrier 2 is installed in the casing 1. In this state, the sealing member 4 is expanded by introducing exhaust gas of an engine into the casing 1 and burning out the combustible film 5, whereby the sealing member 4 expanded through absorption of gas is supported firmly between the carrier 2 and the casing 1.
