Mixing chamber for ammonia gas and exhaust fumes of catalytic converter of internal combustion engine of motor vehicle, has openings configured such that surface of cone intersects openings between top and base of wall

摘要

The chamber (231) has an injection device injecting a reducing product in a guiding conduit (232). A conical shaped wall is arranged in the conduit in downstream from the injection device. An apex of the wall is oriented toward the injection device. The wall is formed with crossing openings (211-214, 221-223) placed at different levels along the axis of the cone. The openings are configured such that the surface of the cone intersects the openings between the top and the base of the wall. An independent claim is also included for an exhaust fumes catalytic converter for an internal combustion engine, comprising a case.
