Abstract
The present invention includes a manifold catalytic converter. The catalytic converter is positioned immediately adjacent the manifold. The manifold and the converter end cone are cast from a single integral piece. The manifold/converter end cone casting includes an end cone portion having an end cone wall having a shoulder formed therein for engaging the front face of a catalytic converter substrate. A lip or ledge extends from the shoulder and surrounds and engages the outer surface of the ceramic substrate immediately adjacent the front face of the substrate. A metal shell is connected to the end cone and is spaced apart from the ceramic substrate. A support material is provided between the ceramic substrate and the metal shell. A second end cone is connected to the shell.
Claims10
A manifold catalytic converter comprising:
- a ceramic substrate having a catalytic coating thereon;
- said ceramic substrate having a front face, rear face and an outer surface connecting said faces;
- a single piece integral casting comprising a manifold, first converter end, shoulder, lip, and shell;
- said first converter end immediately adjacent said manifold, said first converter end being defined in part by a wall that expands from a first end connected to the manifold toward a second end, said wall having an inside surface in fluid communication with said manifold and said ceramic substrate;
- said shoulder being formed at the second end, said shoulder being constructed and arranged to engage the front face of the ceramic substrate;
- said lip extending from the shoulder and surrounding a portion of the outer surface of the ceramic substrate immediately adjacent both the front face and the portion of the outer surface of the ceramic substrate;
- said shell extending from the lip to house said substrate, said shell being spaced a distance from the outer surface of the ceramic substrate;
- a resilient mat positioned between the shell and the ceramic substrate;
- and wherein the shoulder and lip are positioned to prevent high pressure and high vibration exhaust flows from impinging on the resilient mat and prevent the mat from eroding;
- and
- a second converter end secured to the shell.
