<P>PROBLEM TO BE SOLVED: To provide an exhaust gas turbocharger structure for internal combustion engine, a driving system equipped with the exhaust gas turbocharger structure, and a setting method of the driving system. <P>SOLUTION: The exhaust gas turbocharger structure is provided with an exhaust gas turbocharger having an exhaust gas turbine installed inside an exhaust gas line connected to an exhaust gas exit of an internal combustion engine, and a compressor which is installed inside a supercharging air line connected to an air inlet of the internal combustion engine and is connected to the exhaust gas turbine in a rotatable and drivable manner; and an exhaust gas recirculation device having an inlet connected to the exhaust gas line, and an exit connected to the supercharging air line so that the exhaust gas branched from the exhaust gas line enters into the supercharging air line at an exhaust gas entering position. The exhaust gas entering position is located at a fluid compressing route inside the compressor so that the exhaust gas which flows into the compressor simply compensates the pressure difference between the entering pressure of the exhaust gas into the fluid compressing route and a target supercharging pressure and is compressed from the entering pressure to the target supercharging pressure. <P>COPYRIGHT: (C)2011,JPO&INPIT |
