ABSTRACT:
An exhaust gas cooling and particulate scrubbing system for automobiles includes a first stage intercooler for initial, indirect cooling of the exhaust gas and a direct exhaust gas cooling and scrubbing device preferably positioned downstream in the exhaust system therefrom. The intercooler is designed to provide circulation of a liquid cooling medium by convection and has airflow ducts positioned within a surrounding jacket oriented to permit air to move therethrough during movement of the automobile. The a direct exhaust gas cooling and scrubbing device passes the exhaust gas through a liquid cooling medium whereby the exhaust gas is cooled in an effort to trap suspended particulates in the liquid cooling medium.
