Description

CATALYTIC CONVERTER WITH MOUNTING DEVICE FOR A HOT EXHAUST GAS OXYGEN SENSOR
CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application claims priority to U.S. Utility Application No.
1 1/856,931 , filed September 18, 2007, and U.S. Provisional Application No. 60/872,588, filed December 1 , 2006, which is hereby incorporated by reference.
FIELD
[0002] The present disclosure relates to automotive catalytic converters. More particularly, the disclosure pertains to such converters having the capability of mounting a hot exhaust gas oxygen sensor between two cakes or bricks of catalytic material carrying substrates.
BACKGROUND
[0003] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
[0004] Prior vehicular emission monitoring systems utilize emission monitoring oxygen sensors on either end (i.e., upstream and downstream) of a catalytic converter for monitoring converter performance. With recent governmental regulatory changes, automotive manufacturers are now requiring mid-bed sensors, i.e., sensors mounted between two bricks of catalytic material carrying substrates inside the converter housing. This arrangement yields improved converter performance measurement, because the upstream substrate catalyst tends to degrade faster than the downstream substrate catalyst.
[0005] Providing a mid-bed sensor mounting arrangement has, in the past, raised problems of management of heat radiating from the converter shell in the shell area between the substrates. There is therefore seen to be a need in the converter art to provide a mid-bed sensor mounting arrangement which additionally provides insulation between exhaust flow and the converter shell located in the mid-bed region. SUMMARY
[0006] A catalytic converter having a housing holding upstream and downstream catalytic substrates includes a ring located between the substrates, the ring having a gap therein for receipt of a mid-bed oxygen sensor. The ring traps a layer of insulating material between the ring and the converter housing or shell surface surrounding the inter-substrate gap. The ring is coupled to the housing by using a plurality of ring embossments extending toward the housing.
[0007] Further areas of applicability will become apparent from the description provided herein. It should be understood that the description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.

[0018] Fig. 9 is a similar cross-sectional view to that of Fig. 8.
DETAILED DESCRIPTION [0019] With reference to Figs. 1A-1 D, a ring for holding insulation and mounting an oxygen sensor is shown and designated 100. Ring 100 includes a gap 102 for receipt of an oxygen sensor through the shell of the converter and extending therein between the catalytic substrates. Circumferentially spaced about ring 100 are a plurality of, in this case four, embossment regions 104a-d at which the ring 100 is coupled to the converter shell in a manner to be discussed below.
[0020] Ring 100 forms a channel 110 between itself and the converter housing for positioning of a layer of insulative material between the ring and the housing shell.
[0021] Figs. 2A-2D are similar to Figs. 1A-1 D but show a ring 200 whose embossments are of a smoother curvilinear shape as seen from Fig. 2D. The embossment shape disclosed in Figs. 2A-D is preferred, due to its ease of manufacturing. Embossment region 204a has less sharp corners than embossment 104a of Fig. 1 D. With this arrangement of Fig. 2D, there is less likelihood of metal tearing during stamping of the rings. [0022] With reference to Fig. 3A and Fig. 3B, a catalytic converter 300 has a central shell housing first and second catalytic material carrying substrates 310a and 310b separated by a mid-bed gap 308. Insulating ring 100 includes a gap in communication with a sensor mounting boss 306. Conventionally, converter 300 includes an input cone 302 and an output cone 304. Boss 306 receives an oxygen sensor (not shown) which extends into the gap 308. In this manner, an upstream sensor and the sensor mounted at boss 306 are used to monitor the performance of catalytic substrate 310a. [0023] Fig. 4 is a partial cross-sectional perspective view of the converter of Figs. 3A-3B and essentially takes a view at the mid-bed section towards substrate 310b. Spaced around the converter shell 300 which lies over ring 100 are a plurality of perforations 502a-d which are located over each embossment area 104a-d of ring 100. As seen from Fig. 4, each embossment has a dimple or button 105a-d formed therein for receipt in a corresponding perforation 502a-d in housing shell 300. Insulation 500 is trapped between ring 100 and converter shell 300 in this mid-bed area. Sensor mounting boss 306 is located at the gap in ring 100 and receives an oxygen sensor (not shown). Once ring 100 and its embossment region buttons 105 have been properly located and inserted in openings 502, a puddle weld is performed at each opening 502. For example, a MIG welder could flow molten material onto the button areas 105 by flowing through perforations 502, thereby attaching ring 100 to shell 300.
[0024] Fig. 5 presents embossment region 104a in more magnified detail.
[0025] Fig. 6 is essentially the same as Fig. 5. [0026] With reference to Figs. 7-9, an alternative mounting arrangement for ring 100 is presented. In the embodiment of Figs. 7-9, ring 100 is coupled to shell 300 via a mechanical coupling rather than by welding. The mechanical coupling at each embossment area 104 is accomplished using a pair of tools~a male tool on the outside of shell 300 and a female tool impressed against the inner surface of mounting ring 100 opposite to the male tool. Through using these tools, at each embossment location, shell 300 is indented as at 802 by the male tool bearing against the outside surface of shell 300 while ring 100 is deformed to form a U-shaped section 702a which surrounds indentation 802 with legs 704a and 705a in a crimping manner to effect a mechanical linkage between ring 100 and shell 300.
[0027] The invention has been described with reference to embodiments which have been set forth for the sake of example only. The scope and spirit of the invention will become apparent from proper interpretation of the appended claims.
