Abstract

Pakokaasukatalysaattori (10), jossa on pakokaasukatalysaattorin kotelo (11), useita katalysaattorimoduuleja (14) vastaanotettuina pakokaasukatalysaattorin koteloon, tukiristikko (15) ja vastakannatin (17), joka käsittää useita toistensa suhteen samansuuntaisesti kulkevia vastakannatintukia (16), jolloin katalysaattorimoduulit on puristettu tukiristikon (15) ja vastakannattimen (17) väliin siten, että katalysaattorimoduulit (14) ovat tukiristikkoa (15) vasten ensimmäisillä läpivirtauspäillä ja vastakannatinta (17) vasten toisilla läpivirtauspäillä, ja useita pidättimiä (18), jotka vaikuttavat pakokaasukatalysaattorin kotelon kotelorakenteisiin (19) ja painavat vastakannatintukia (16) katalysaattorimoduulien (14) toisia läpivirtauspäitä vasten. Jokaisen vastakannatintuen (16) alueella jokainen pidätin (18) vaikuttaa vastaavan vastakannatintuen (16) päihin, jotka sijaitsevat vastakkain toisiaan, joka ensimmäisellä osuudella (20) painuu vastaavaa vastakannatintukea (16) vasten, joka toisella osuudella (21) työntyy vastaavan vastakannatintuen (16) syvennykseen (22), ja joka kolmannella osuudella (23) ulottuu pakokaasukatalysaattorin kotelon (11) kotelorakenteen (19) läpi, joka kulkee poikittain vastaavaan vastakannatintukeen (16) nähden. Vastaava pidätin (18) käsittää jousielementin (25), joka tukeutuu yhtäältä vastaavan pidättimen (18) ensimmäiseen osuuteen (20) ja toisaalta vastaavaan kotelorakenteeseen (19).
