Abstract
Abstract A device for automobiles for preventing air contamination by forcing compressed air to an engine exhaust manifold for reburning the incompletely burned components of the engine exhaust gas. The device comprises a compact air-pump-alternator consisting of an air pump portion and an alternator portion connected in series with the air pump along a common shaft. The air pump delivers compressed air generated thereby into the alternator for cooling. The compressed air, which is heated by cooling the alternator, is forced into the engine exhaust manifold for effectively reburning the incompletely burned components.
