摘要： The present invention provides a multi-cylinder engine capable of inhibiting an EGR cooler from being damaged and at the same time making the EGR cooler compact. On the assumption that a direction where a crank shaft spans is taken as a front and rear direction and a widthwise direction of a cylinder head (2) perpendicular to this front and rear direction is deemed as a lateral direction, an intake-air distributing passage wall (3) is attached to one lateral side surface of the cylinder head (2) and an exhaust-gas converging passage wall (4) is attached to the other lateral side of the cylinder head (2), the exhaust-gas converging passage wall (4) having an interior area communicated with an interior area of the intake-air distributing passage wall (3) through the EGR cooler (6). In this multi-cylinder engine, an intake-air inlet pipe (5) is made to stand up at an upper portion of the intake-air distributing passage wall (3) and the EGR cooler (6) spans above the intake-air distributing passage wall (3). Further, the intake-air inlet pipe (5) is arranged side by side with the EGR cooler (6).
