Summary:A multi-cylinder engine wherein a direction in which a crank shaft spans is a front and rear direction and a widthwise direction of a cylinder head perpendicular to the front and rear direction is a lateral direction, the multi-cylinder engine comprising the cylinder head which has one lateral side to which an intake-air distributing passage wall and has the other lateral side to which an exhaust-gas converging passage wall, a common rail being arranged around the cylinder head. In this multi-cylinder engine, the common rail is arranged immediately lateral of the intake-air distributing passage wall, thereby positioning the intake-air distributing passage wall between the cylinder head and the common rail. Preferably, an intake-air inlet pipe is made to stand up at an upper portion of the intake-air distributing passage wall and is provided with an intake-air flange portion, which is positioned just above the common rail.
