<P>PROBLEM TO BE SOLVED: To prevent a rise of an intake temperature in an internal combustion engine having an exhaust turbo charger and attached with a low-pressure loop exhaust gas recirculation system. <P>SOLUTION: In the internal combustion engine 0 including a low-pressure loop type exhaust gas recirculation system, a bypass path 7 connecting the upstream of a compressor 51 with the downstream of a throttle valve 33 is provided. The operation of opening a bypass valve 71 takes place when supercharging so as to reflux part of the supercharged intake air to the upstream of the compressor 51. Since a heat capacity of an intake path 3 and the bypass path 7 in total is increased substantially, the intake temperature can be lowered. <P>COPYRIGHT: (C)2012,JPO&INPIT |
