ABSTRACT:
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 perpendicular to this front and rear direction is deemed as a lateral direction, an intake-air distributing passage wall is attached to one lateral side surface of the cylinder head and an exhaust-gas converging passage wall ached to the other lateral side of the cylinder head, the exhaust-gas converging passage wall having an interior area communicated with an interior area of the intake-air distributing passage wall through the EGR cooler. In this multi-cylinder engine, an intake-air inlet pipe is made to stand up at an upper portion of the intake air distributing passage wall and the EGR cooler is above the intake-air distributing passage wall. Further, the intake-air inlet pipe is arranged side by side with the EGR cooler.
