This patent specification discloses an engine exhaust gas reflux apparatus constructed so as to purify exhaust gas coming out of various engines mounted on vehicles or ships for preferably preventing NOx from being discharged in the atmosphere. The engine exhaust gas reflux apparatus has a technical construction which removes dust particles and impurities contained in exhaust gas by means of a dust collector installed at the discharge port of the exhaust manifold, draws purified exhaust gas into the intake manifold and lowers combustion temperature produced when the engine fuel burns to eliminate NOx out of exhaust gas coming out of the exhaust manifold.
