Abstract: An EGR system has an EGR distributor in the form of a single plate integrally equipped with an exhaust gas passage and a coolant passage for recirculated exhaust gas therewith. The lengths of each exhaust gas passages for the recirculated exhaust gas to reach each cylinder are equal to each other, whereby the amount of the exhaust gas recirculated to each intake passage is same and the overall efficiency of the EGR system is improved. The EGR distributor is preferably manufactured in the form of a single component by AL die casting method.
