Method for producing an overlapping connection, and body component for a vehicle
11759841 · 2023-09-19 · ·

The disclosure relates to a method for producing a overlapping connection, in which at least two overlapping components are connected to one another via a folded flange, with a first edge of a first component being folded over a second edge of a second component to form the folded flange, along with a body component that includes such an overlapping connection for a vehicle and a stamping tool for such a body component. According to the disclosure at least one connection region is formed on the folded flange, in which the stamping tool stamps the first component through the second component at least one stamping point, with displaced material of the first component passing into the second component and producing a positive connection.

Metal foil catalyst for the control of emissions from diesel engines

A diesel engine emissions catalyst which may be used to fill a niche between standard oxidation catalyst and diesel particulate filters for control of diesel particulate matter. The catalyst includes a structure (substrate) comprising one or more coated, corrugated micro-expanded metal foil layers. The coated surface may be a high surface area, stabilized, and promoted washcoat layer. The corrugated pattern may include a herringbone-style pattern that, when in use, is oriented in a longitudinal direction of the diesel engine exhaust flow. The micro-expanded metal foil provides small openings or eyes that, as the exhaust flow passes through the catalyst (transverse to the eye opening), particulates in the flow impinge on the surface and becomes trapped in the eyes. The catalyst may be used to treat a locomotive engine exhaust stream and may be used with a selective catalyst reduction system.

Pierced thermal interface constructions

Pierced thermal interface constructions including a thermal interface material (TIM) structure comprising: a TIM sheet comprising a plurality of piercings, where each of the plurality of piercings comprises a cavity and displaced material, and where the displaced material from each of the plurality of piercings protrudes away from the TIM sheet.
