Abstract (en)
An apparatus (2) controls heat transfer between a cooling heat medium for cooling an internal combustion engine and an inner wall (18) of a cylinder block (14). The heat medium flows through the groove-like flow passage provided between the inner wall (18) and an outer wall (20). The apparatus (2) includes a lower side cover (4) and a guiding member (6, 8). An upper side of the inner wall (18) is uncovered with the cover (4) and exposed directly to the heat medium so that the upper side of the inner wall (18) is cooled easier than the lower side. Therefore, the difference in temperature in a vertical direction of each of the bores (18a-18d) can be reduced. The guiding member (6, 8) guides the heat medium having a lower temperature from the lower side to the upper side of the inner wall (18) in the direction of arrangement of the cylinders at a plurality of points. Thus, the upper portion of the bores 18a-18d can be sufficiently cooled even at down stream of the water jacket (16) and differences in temperature among the bores (18-18d) of the cylinders #1-4 can be reduced. Thus, not only differences in temperature in the up-and-down direction of each of the cylinder bores (18a-18d) but also differences in temperature among the cylinders (#1-4) can be reduced without partitioning the heat medium among the cylinders (#1-4).
