According to one embodiment, an apparatus () for mounting to an inner wall () of an exhaust tube () includes a tube engagement surface () and an exhaust engagement surface (A). The tube engagement surface comprises a convex surface of a constant first radius of curvature about a first axis. The exhaust engagement surface is adjacent the tube engagement surface, and includes a concave surface of a second radius of curvature about a second axis generally perpendicular to the first axis.

Apparatus for facilitating reductant decomposition and mixing

Apparatus for facilitating reducant decomposition and mixing

A system including a reductant source storing reductant, an ammonia generation system configured to generate gaseous ammonia via cavitation, and a gaseous ammonia delivery device in fluid communication with the ammonia generation system and an exhaust system. The system may selectively activate the ammonia generation system responsive to a detected temperature of an exhaust gas of an exhaust system being equal to or below a predetermined value. The ammonia generation system may utilize ultrasonic cavitation or laser cavitation to generate gaseous ammonia to be delivered to the exhaust system responsive to the temperature of the exhaust gas of the exhaust system being equal to or below the predetermined value. If the temperature of the exhaust gas of the exhaust system above the predetermined value, a dosing module to dose reductant to the exhaust system may be activated.
