Abstract: An apparatus for rapidly evaporating liquid includes an exhaust flow channel having opposing openings including an upstream opening and a downstream opening. The channel defines an exhaust path proceeding from the upstream opening through the exhaust flow channel and through the downstream opening. Within the exhaust flow channel, a conduit path includes repeated passes transverse to the exhaust path. Attached to the exhaust flow channel proximate the downstream opening, a spray fixture is coupled to an exit port of the conduit. The spray fixture includes a divider to divide fluid from the exit port into multiple streams and an aimer to direct the multiple streams into the exhaust path.

Abstract: An exhaust baffle apparatus includes an enclosure having longitudinal, lateral, and anterior dimensions. The apparatus defines an internal volume defining an airflow path proceeding from an intake opening to an exhaust opening. There are a multiplicity of mixers within the enclosure. Each mixer includes a length spanning the lateral dimension of the enclosure. Each mixer further comprises a hollow airfoil substantially open at lateral ends of the mixer and at least one vent oriented toward the exhaust opening. A different feature involves a method of dampening noise and heat form engine exhaust.
