Abstract
A catalyst carrier body for exhaust systems of internal combustion engines includes a configuration for temperature measurement and/or heating walls of the catalyst carrier body. At least two layers, namely an upper layer and a lower layer, rest predominantly tightly against one another have identically structured metal foils with a thickness of from 0.02 to 0.1 mm. At least one of the layers has an outward bulge forming at least one void along the layers and between the layers. At least one temperature sensor and/or heat conductor extends in the void and may have supply lines extending in the void.
Claims39
In an exhaust system of an internal combustion engine, a catalyst carrier body comprising:
- a) at least an upper layer and at least a lower layer resting predominantly tightly against one another defining walls of the catalyst carrier body and having identically structured metal foils with a thickness of from 0.02 to 0.1 mm;
- b) at least one of said layers having an outward bulge forming at least one void along said layers and between said layers;
- c) at least one of temperature measuring means for temperature measurement having at least one temperature sensor extending into said void, or heating means for heating said walls having a heat conductor extending into said void.
