Abstract

Polttomoottorin pakokaasunjälkikäsittelyjärjestelmä (3), nimittäin polttomoottorin SCR-pakokaasunjälkikäsittelyjärjestelmä, jossa on reaktiotilan (10) vastaanottama SCR-katalysaattori (9), reaktiotilaan (10) ja siten SCR-katalysaattoriin (9) johtava pakokaasunsyöttöjohto (8), reaktiotilasta (10) ja siten SCR-katalysaattorista (9) poisjohtava pakokaasunpoistojohto (11), pakokaasunsyöttöjohtoon (8) järjestetty tuontilaite (16) pelkistysaineen, erityisesti ammoniakin tai ammoniakin esiasteen tuomiseksi pakokaasuun, ja pakokaasunsyöttöjohdosta (8) alavirtaan tuontilaitteeseen (16) järjestetty sekoitusmatka (18) pakokaasun sekoittamiseksi pelkistysaineen kanssa ylävirtaan reaktiotilasta (10) tai SCR-katalysaattorista (9). Pakokaasunjälkikäsittelyjärjestelmässä (3) on useita puhalluslaitteita (24) SCR-katalysaattorin (9) puhtaaksi puhaltamiseksi. Lisäksi pakokaasunjälkikäsittelyjärjestelmässä (3) on puhalluslaitteille (24) yhteinen paineakku (25), joka on muodostettu ympyrämäiseksi tai polygonimaiseksi, jolloin puhalluslaitteille (24) voidaan syöttää SCR-katalysaattorin (9) puhtaaksipuhaltamisainetta yhteisestä paineakusta (25).
