Abstract
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 () is attached and has the other lateral side to which an exhaust-gas converging passage wall () is attached, an EGR cooler being interposed between an exhaust-gas converging passage and an intake-air distributing passage. In this multi-cylinder engine, the EGR cooler () spans in the front and rear direction laterally of a cylinder block () and the exhaust-gas converging passage wall () is positioned just above the EGR cooler (). Preferably, an EGR gas lead-out pipeconducted out of the EGR cooler () is arranged rearwards of an engine cooling fan () so that the engine cooling air produced by the engine cooling fan () might blow against the EGR gas lead-out pipe ().
