Abstract
Systems and devices for delivering a fluid to an exhaust system. An inlet is configured for receiving the fluid, and a conduit includes openings for expelling the fluid into the exhaust system. A compact gaseous delivery system may include a first conduit in fluid communication with a fluid source, a second conduit in fluid communication with the first conduit, and a plurality of additional conduits in fluid communication with the second conduit and including a plurality of openings for expelling the fluid into the exhaust system. The first conduit, second conduit, and plurality of additional conduits may have axes that are substantially coplanar to form the compact gaseous delivery system that may be disposed within the exhaust system. Implementations may include openings with varying diameters. Other implementations may include a volute conduit with openings.
