As shown in FIGS. 1 and 2, a cooling water passage 6 is formed in the multiple Siamese cylinder block 2 so as to go around the continuous cylinder bore wall 4. As shown in FIGS. The cooling water passage 6 extends from one longitudinal end 2 a of the cylinder block 2 along one side (intake manifold side) of the cylinder bore wall 4 to the other longitudinal end 2 b of the cylinder block 2 , and then makes a U-turn and extends along the other longitudinal end 2 b of the cylinder bore wall 4 . side (exhaust manifold side) to one end 2a in the longitudinal direction of the cylinder block. A cooling water inlet portion 8 to the cooling water passage 6 is formed in one end portion 2a of the cylinder block, and the cooling water pumped from the water pump 10 passes through the cooling water inlet portion 8 to the inflow side end of the cooling water passage 6. flow into the department. The cooling water outlet section 12 from the cooling water passage 6 to the water jacket in the cylinder head is
It is provided above the outflow side end of the cooling water passage and adjacent to the cooling water inlet section 8 . A guide member 1 is installed in the cooling water inlet section 8.
4 is provided. The guide member 14 extends from the outer wall inner surface 16 of the cooling water inlet portion toward the cylinder bore wall outer surface 18 of the portion facing the guide member 14, and extends from the outer wall inner surface 16 of the cooling water inlet portion
The cooling water flowing in from the cooling water inlet part 8 by blocking the cooling water outlet part 12 from the cooling water outlet part 12 flows in one direction in the cooling water passage 6, except for water leaking through the gap means described later. There is. A gap 20 is provided between the tip of the guide member 14 and the cylinder bore wall outer surface 18 so that a portion of the cooling water flowing into the cooling water passage 6 from the cooling water inlet 8 leaks to the cooling water outlet 12. Cooling water leaks to the cooling water outlet portion 12 side through this gap 20, eliminating the difference in water temperature before and after the guide member 14.

When the intersection of the tangent 22 at the tip of the guide member 14 and the cylinder bore wall outer surface 18 is A, and the angle between the line 24 connecting the bore center and A is α, 0<α<90°. The bending angle is set as follows. This prevents the cooling water from leaking to the cooling water outlet section 12 side more than necessary.

The guide member 14 has an arcuate shape so that it can be fitted into the circular cooling water inlet portion 8 formed in the cylinder block. Thereby, the amount of cooling water leaking from the top and bottom of the guide member 14 can be limited. Furthermore, by forming the guide member 14 in an arc shape, the flow of the cooling water that has made a U-turn and flowed is promoted by the arc shape of the guide member 14, and collides with the water leaking from the upper and lower parts of the guide member 14. , it is as if a wall had been built, and the amount of leakage can be limited. Further, the guide member 14 is formed integrally with a gasket 30 interposed between the water pump 10 and the cylinder block 2. This prevents an increase in parts and assembly man-hours.

Water discharged from the radiator first flows through the intake side passage 28 of the cylinder head 26, is sucked into the water pump 10, and is supplied to the cylinder block 2. In the cylinder block 2, the cooling water flows through the intake side passage of the cooling water passage 6 from the first cylinder to the fourth cylinder.
Make a U-turn around the No. 1 cylinder, return to the No. 1 cylinder through the cooling water passage on the exhaust side, go up to the cylinder head from there, and go around the cylinder head plug and the exhaust side passage toward the No. 4 cylinder. so that it flows and exits to the radiator side.
Cooling water channels are set up.

4, most of the cooling water does not flow directly to the cooling water outlet section 12, but instead flows through the intake side of the cooling water passage 6.
It flows from the first cylinder to the fourth cylinder. The water then makes a U-turn around the No. 4 cylinder, flows through the exhaust side of the cooling water passage 6 from the No. 4 cylinder toward the No. 1 cylinder, and flows from the cooling water outlet portion 12 to the cylinder head. While flowing in the cooling water passage 6 around the continuous cylinder bore wall 4, the cooling water cools the cylinder bore wall and heats itself up. Therefore, the temperature of the cooling water tends to be higher at the cooling water outlet section 12 than at the cooling water inlet section 8.

に一体に成形しても問題が生じなくなる。In the present invention, since the gap 20 is provided between the tip of the guide member 14 and the cylinder bore wall outer surface 18, a portion of the cooling water in the cooling water inlet section 8 passes through the gap 20 and reaches the cooling water outlet. It leaks to the part 12 side. Therefore, the circumferential temperature difference in the portion of the cylinder bore wall 4 facing the guide member 14 is reduced, and the thermal strain that conventionally occurs in this portion is suppressed. By suppressing thermal distortion, the sliding performance of the piston of the first cylinder against the cylinder bore wall becomes better. Further, since an excessive clearance is not generated between the piston and the inner surface of the cylinder bore wall, there is no increase in oil consumption and no worsening of piston slap noise. By leaking cooling water through the gap 20, the guide member 14
The pressure difference before and after the guide member 14 is also reduced, deformation of the guide member 14 due to water pressure is prevented, and durability is also improved. Further, since a large pressure difference is not applied to the guide member 14, the guide member 14 is moved between the water pump gasket 30 and the water pump gasket 30, as described above.
No problem will occur even if it is integrally molded.

At the same time, since a gap 20 is provided between the tip of the guide member 14 and the cylinder bore wall surface 18, a part of the cooling water leaks from the cooling water inlet part 8 to the cooling water outlet part 12 side,
The temperature gradient in the circumferential direction of the portion of the cylinder bore wall facing the guide member can be made gentler, and thermal distortion of the cylinder bore wall can be reduced.
