One piece catalytic converter with integral exhaust manifold

Abstract

The present invention relates to exhaust system assemblies and, more particularly, to a one piece catalytic converter can with an integral exhaust manifold. Disposed within the catalytic converter can are the catalytic conversion components. Coupled to the one piece converter can and integral exhaust manifold is a second end cone to provide a substantially air tight seal to the assembly.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of U.S. Provisional Application No. 60 / 533,233, filed on Dec. 30, 2003. The disclosure(s) of the above application(s) is (are) incorporated herein by reference.FIELD OF THE INVENTION [0002] 1. Technical Field [0003] The present invention relates to catalytic converters and, more particularly to a one piece catalytic converter can with an integral exhaust manifold. Preferably the integral catalytic converter can and exhaust manifold are formed as a unitary casting. While numerous materials may be suitable for casting the one piece catalytic converter and exhaust manifold, cast irons and, preferably SiMo cast irons are preferred. [0004] In addition to the one piece catalytic converter with integral exhaust manifold, the present invention also relates to a method of welding an end cone to the one piece catalytic converter and integral exhaust manifold.

AI Technical Summary

Benefits of technology

[0007] In a first instance, the present invention addresses the above described drawbacks, among others, by providing a catalytic converter assembly employing a one-piece catalytic converter can and integral exhaust manifold to limit the number of overall components in the assembly.

Problems solved by technology

Among the perceived drawbacks to this type of catalytic converter assembly are the costs associated with assembling multiple pieces to arrive at a useful component and the inherent gas leak paths associated with multi-piece components, especially those employing mechanical fasteners to join the pieces.
