Embodiment Construction
[0013] In conjunction with Fig. 1 and Fig. 2, a single-row automobile engine body is composed of a cast crankcase 2 and a cylinder block 1. There is a water trap outside the hole wall, and the centerlines of the cylinder bores are located in the same plane. The distance between the walls of the cylinder 3 provided on the cylinder block 1 is 8 mm, and the distance between the cylinder centers / bore diameter is L 0 / D=1.11. In this embodiment, the design of the water jacket between two adjacent cylinders is abandoned. In the water interlayer, within 60mm below the top surface of the body, support columns are symmetrically arranged on both sides of the plane where the center line of the cylinder liner hole is located. ; For the convenience of casting production, a mud core support 4 is provided in the interval between two adjacent cylinders 3 (refer to Figure 2). In order to solve the problem of enhanced cooling of the engine, intersecting cooling water holes 6 (refer to FIG. 2 )...
