Abstract

Настоящее изобретение относится к устройству для обработки выхлопных газов дизельного двигателя, содержащему фильтр для улавливания твердых частиц выхлопа дизельного двигателя. Настоящее изобретение также относится к способу получения и использования указанного устройства. Фильтр для улавливания твердых частиц (ДФЧ) в соответствии с настоящим изобретением имеет покрытие, полученное из золя, средний размер частиц которого составляет менее 100 нм, предпочтительно менее 50 нм, и перед фильтром для улавливания твердых частиц относительно направления потока выхлопных газов присоединен катализатор окисления частиц (КОЧ), содержащий, по меньшей мере, частично открытые каналы для прохождения выхлопных газов.
