Abstract
PURPOSE: An EGR system to be obtained sufficient reducing effects of NOx without providing torque fluctuation and misfire by equalizing spouting amount, timing and velocity of EGR gas fed into each air cylinder.
CONSTITUTION: In concurrence of providing EGR gas feeding branch passages 20aW20d having each one extremity opening into each air cylinder 4aW4d of a 4-cylinder internal combustion engine with providing auxiliary air intake valves 21aW21d which open and close those opening extremities, are conducted other extermities of each branch passage to an EGR gas common passage 29. Then, the contrivance is made up such that with auxiliary air intake valves 21aW21d of each air cylinder opened at exhasut stroke latter cycles and air intake stroke terminal cycles which are respectively commensurate, at the same time as the length of passages 29a, 29d are made equal so as to even up the passage resistance to one another at the mixed air passage 29 plying between the air cylinders which open their valves in synchronization with the auxiliary air intake valves, the length of passages 29b, 29c are made equal, or each branch passage are inserted with orifices which are properly selected.
