Beschreibung
Zusammenfassung:	A pump attaching portion is formed at a specified outside portion of an engine body beside a boss portion of a cylinder-head fastening bolt in such a manner that the pump attaching portion is continuous from the boss portion. The pump attaching portion has an attachment face, which contains a cooling-water introducing port, which is located on the outside of the flange wall and faces toward an engine front side in such a manner that the position of the attachment face is retreated from the flange wall. Accordingly, the sufficient pump-support rigidity can be ensured, restraining the pump attaching portion from projecting greatly toward the side of the engine body.
