INTAKE SYSTEM STRUCTURE OF INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To provide an intake system structure of an internal combustion engine capable of preventing corrosion and an abnormal sound, by properly processing a condensate in an intercooler.

SOLUTION: A condensate introducing part (19) is arranged in an intake manifold (12) so that an introducing port (17a) and a condensate introducing plate (19a) overlap in an introducing port-direction view of an EGR passage (17) and a discharge part (19e) becomes the counter side of the introducing port side. The condensate introducing part (19) is adjusted by energizing force of a coil spring (20) so that the condensate introducing plate (19a) becomes parallel to the flow direction of suction air when EGR gas is not introduced from the introducing port (17a) and a rotation degree in the direction to the counter side of the introducing port side changes depending on a flow rate of the EGR gas when EGR is introduced.
