  "textContent": "Provided is an engine exhaust gas purification device which reduces or eliminates the electric power required for raising the pressure of exhaust gas recirculation (EGR) gas extracted from the upstream side of an exhaust gas turbocharger to be used for EGR after cleaning processing by an exhaust gas cleaning unit. An engine exhaust gas purification device (1) for reducing and eliminating air pollution substances contained in exhaust gases discharged from a main engine (10) equipped with an exhaust gas turbocharger (20) includes an exhaust gas cleaning unit (70) that cleans a portion of the exhaust gases introduced as an EGR gas from an exhaust line (L1) located at the upstream side of a turbine unit (21) of the exhaust gas turbocharger (20), and a recirculation exhaust gas turbocharger (60) that raises the pressure of the EGR gas which is caused to pass through the exhaust gas cleaning unit (70) by a recirculation compressor unit (62) coaxial with the recirculation turbine unit (61) which is dispose at the upstream side of the exhaust gas cleaning unit (70) and is driven by using the EGR gas.",
