Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subject to the restriction of embodiment.
As shown in Figure 3 and Figure 4, it has shown respectively according to longitudinal sectional view and transverse sectional view between cylinder block two cylinders of the large diesel engine of dry cylinder liner structure of the present utility model.As we can see from the figure, cooling jacket between the two adjacent cylinder of dry construction cylinder sleeve cylinder block is cast into entity, and process multiple slotted holes 4 by mach method on this entity, be used for replacing the special-shaped slotted hole between original two cylinders, but role is consistent with different in nature slotted hole, that is, the cooling liquid in cooling jacket (for example water) is guided to cylinder block opposite side from cylinder block one side by described slotted hole 4.Reach the object of cooling cylinder.
The arrangement mode of slotted hole 4 can be linear array, and oblique line is arranged.Heterogeneous Permutation etc.In this concrete enforcement, the arrangement mode of slotted hole is for to be the single-row layout of certain intervals along vertical direction.The number of slotted hole need to pass through to calculate total discharge area, then determines and the quantity of circular hole by the area calculating, and Circularhole diameter can be determined by the thickness of cylinder wall 5.The slotted hole 4 of processing, can make the wall thickness of the cylinder wall 5 between two cylinders dwindle like this, thereby the in the situation that of equal cylinder core distance, the cylinder block that is processed into slotted hole scheme can be larger than the cylinder block cylinder diameter that is cast as different in nature hole scheme.Reach the object that increases diesel engine discharge capacity.There is not scab problem in the cylinder block that is simultaneously processed into slotted hole scheme, thereby guarantees water jacket heat radiation evenly.Improve the cooling of diesel engine.
