Abstract

Ohitusventtiilijärjestely (1) polttomoottorin (2) pakokaasujärjestelmää varten käsittää venttiilin (5) ja putkiston, jossa on ensimmäinen tuloaukko (3a), toinen tuloaukko (4a), ensimmäinen poistoaukko (3b) ja toinen poistoaukko (4b). Venttiilin (5) ensimmäisessä asemassa virtaus ensimmäisestä tuloaukosta (3a) ensimmäiseen poistoaukkoon (3b) ja toisesta tuloaukosta (4a) toiseen poistoaukkoon (4b) on sallittu, ja virtaus ensimmäisestä tuloaukosta (3a) toiseen poistoaukkoon (4b) ja toisesta tuloaukosta (4a) ensimmäiseen poistoaukkoon (3b) on suljettu. Toisessa asemassa virtaus ensimmäisestä tuloaukosta (3a) toiseen poistoaukkoon (4b) ja toisesta tuloaukosta (4a) ensimmäiseen poistoaukkoon (3b) on sallittu, ja virtaus ensimmäisestä tuloaukosta (3a) ensimmäiseen poistoaukkoon (3b) ja toisesta tuloaukosta (4a) toiseen poistoaukkoon (4b) on suljettu. Keksintö koskee myös pakokaasujärjestelmää.
