Abstract (en)
[origin: WO2020165387A1] The present invention is directed to a method and a device for coating substrates of motor vehicle exhaust gas catalysts. In this respect, the substrates can be flow-though substrates or filter systems ("wall flow"). The invention particularly describes an improvement in such coating processes in which a suspension (washcoat) containing the catalytically active material is applied to or delivered onto such a vertically oriented substrate (monolithic substrate) from above ("metered charge" process).
