Patent ID: 7275526

Claim:
A multi-cylinder engine, on the assumption that a direction where a crank shaft ( 1 ) spans is taken as a front and rear direction and that a widthwise direction of a cylinder head ( 2 ) perpendicular to this front and rear direction is deemed as a lateral direction, which comprises an intake-air distributing passage wall ( 3 ) attached to one lateral side surface of the cylinder head ( 2 ) and an exhaust-gas converging passage wall ( 4 ) 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 an EGR cooler ( 6 ), wherein 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 ) in the front and rear direction, the intake-air inlet pipe ( 5 ) being arranged side by side with the EGR cooler ( 6 ) in the front and rear direction.
