    摘要： 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.

    摘要： An object is to provide an engine-exhaust-gas energy recovery apparatus that can set the fuel consumption rate of an engine to a predetermined value or lower in response to various loads and rotation speeds of the engine, and that can effectively utilize exhaust gas discharged from the engine. Provided are a hybrid turbocharger (3) having a turbine unit (3a) that is supplied with exhaust gas discharged from an engine (2), a compressor unit (3b) that pressure-feeds scavenging-air pressure to the engine (2), and a generator/motor unit (3d) that generates electricity when the turbine unit (3a) is driven; a bypass channel (L2) that allows the exhaust gas supplied toward the hybrid turbocharger (3) to bypass the hybrid turbocharger (3); an engine-load detecting part; an engine-rotation-speed detecting part; a scavenging-air-pressure detecting part; and a control device having a database for calculating a scavenging-air pressure, at which the fuel consumption rate of the engine (2) becomes lower than or equal to a predetermined value, from the detection values of the respective detecting parts. The control device controls an exhaust-gas bypass control valve (V1) so as to control the scavenging-air pressure of the engine (2).
