Abgasvorrichtung und System mit geringer Durchflussdrosselung

摘要

Disclosed herein is an emission control device (16) and system (10) including the emission control device (16). The emission control device (16) comprises a housing (60) having exhaust gas inlet and outlet portions (20, 22). The exhaust gas inlet portion (66) is received within a flared end (64) of an exhaust gas inlet tube (20), and the exhaust gas outlet portion (68) is received within a flared end (64) of the exhaust gas outlet tube (22). Cross-sectional flow areas of the inlet and outlet tubes (20, 22) are less than cross-sectional flow areas of unflared portions (56) of the exhaust gas inlet portion (66) and the exhaust gas outlet portion (68).
