Zusammenfassung:	PURPOSE:To simplify the structure of piping and to attain uniform combustion in a plurality of cylinders, by forming an exhaust-gas recirculating passage to extend along concentrated portions of intake passages, and providing ports for communicating the exhaust-gas recirculating passage and the intake passages with each other. CONSTITUTION:An exhaust-gas recirculating passage 33 for recirculating exhaust gas from an exhaust passage to a plurality of cylinders is formed to extend along concentrated portions of intake passages 19, 19' in the direction of a crankshaft. Further, connecting ports 34 are provided for communicating the exhaut-gas recirculating passage 33 and the intake passages 19, 19' with each other. Thus, by a single exhaust-gas recirculating passage 33, exhaust gas can be distributed substantially uniformly and supplied to a plurality of intake passages 19, 19' extending respectively toward banks on both sides. By employing such as arrangement, it is enabled to simplify the structure of piping and to attain uniform combustion in a plurality of cylinders.
