Inflow chamber for a catalytic converter of an emission control system

摘要

Truncated cone peripheral surface of this utility new type relates to a one for an exhaust gas catalytic converter (2) of the inflow room (1), comprising a cylindrical shell (3) and guide plate (5), of one shell is provided with peripheral surface (31) and two end surfaces (32, 33), (31) and first end surface (32) is composed of exhaust gas can not pass through of material forming, a second end face (33) at least can be part of exhaust gas through, (31) doped with a reducing agent (8) of exhaust gas (4) of entering into port (34), an exhaust guide plate (4) can pass through the material form of the guide plate (5) along the transverse direction from the shell (3) of the second end surface (33) extends to first end surface (32), a guide plate (5) along the lengthways has a tapered section (52), wherein guide plate forming the outer surface shell (3) facing the first end surface (32) of conical section in the shell (3) of the circumferential direction extending at least 90 degrees, in particular at least 135 degrees, more especially more than 180 degrees.
