发明名称 EXHAUST GAS RECIRCULATION DEVICE IN INTERNAL COMBUSTION ENGINE
摘要 <P>PROBLEM TO BE SOLVED: To provide a technique suppressing seeping of a reducing agent added to exhaust gas on the upstream side of a supercharger into an intake passage by a low-pressure EGR device, for regenerating the exhaust emission conversion capacity of an exhaust emission control device, in an exhaust gas recirculation device in an internal combustion engine, performing EGR by using the low-pressure EGR device, especially in the internal combustion engine operating a plurality of superchargers by using energy of exhaust gas from a plurality of cylinder groups. <P>SOLUTION: In this exhaust gas recirculation device for the internal combustion engine with the cylinders of the internal combustion engine divided into the plurality of cylinder groups and the exhaust passage and supercharger provided for every cylinder group, the exhaust passage 62 having a low-pressure passage EGR 72 and the exhaust passage 12 adding the reducing agent on the upstream side of the supercharger, are branched from the exhaust passage corresponding to the plurality of cylinder groups. <P>COPYRIGHT: (C)2008,JPO&INPIT
