Abstract

An exhaust gas-cooling device for use on an exhaust gas conveyance system of a vehicle having an exhaust gas passageway to emit exhaust gases from an engine to an outlet includes an exhaust passageway pipe in fluid communication with the engine, and a micro-venturi mixing chamber pipe in fluid communication with and located downstream of the exhaust passageway pipe. The micro-venturi mixing chamber pipe defines the outlet of the exhaust gas-cooling device and has at least one aperture disposed on a pipe body of the micro-venturi mixing chamber for introducing ambient air into the micro-venturi mixing chamber pipe.
