摘要： A water passage forming member (10) embedded in a connection wall (4) between adjacent bores (3a) (3a) of a multi-cylinder (2) by a casting process is provided with a pair of left and right vertical jacket communication passages (12)(12) for making cylinder jackets (8)(8) within a cylinder block (1) communicate with a head jacket (22), cooling water passages (15) arranged vertically and in multiple stage for making the paired jacket communication passages (12)(12) communicate with each other, and non-hollow portions (11) arranged in multiple stage and alternately with the cooling water passages (15). A pair of left and right cooling water induction portions (13)(13) are disposed in the lower portions of the jacket communication passages (12)(12) and opened toward the cylinder jackets (8)(8), and the paired left and right cooling water induction portions (13)(13) are constructed by spreading a pair of fore and rear cooling water guiding plates (14)(14) projected leftward and rightward, along the respective external circumferential surfaces (3a) (3a) of adjacent fore and rear cylinders (3)(3).
