Abstract
An emission control system for an internal combustion engine cools the exhaust gases sufficiently to condense a substantial portion of the pollutants as a separable liquid or solid phase. The engine exhaust gases are initially cooled and then compressed, again cooled, and work-expanded in an open reversed Brayton cycle to obtain a significant temperature decrease. The resulting cooled gases from this the pollutants are readily separated may be employed to provide refrigeration or air-conditioning for moving vehicles.
