Inferior part of the cylinder block is realized with outer wall clearance fit and is positioned, and the accurate positionin for realizing cylinder sleeve is coordinated at upper and lower two；In cylinder block inner wall
Portion is the up-small and down-big conical surface, and the cylinder block middle part conical surface forms cooling water cavity with outer wall of cylinder jachet, and the setting of the conical surface expands cooling
The space of water cavity, it is ensured that cooling effect, while the lower end of cylinder sleeve upper end closely this seam allowance position is cooling water cavity, it is ensured that cylinder sleeve
Top cooling is reliable.
With being provided with stainless steel gasket on the composition surface of cylinder sleeve cooperation, cylinder block lower part passes through cylinder block with outer wall of cylinder jachet
Twice O-ring seals, and ensures the leakproofness of cooling water cavity.
Increase electronically controlled unit pump installation site in the V-arrangement angle space of the cylinder block of 8 cylinder body of water cooling, basic wall thickness is carried
Up to 10mm~11mm further improves body overall stiffness.
Attachment mounting bracket is provided in machine main body both sides, ensures the abundance of attachment installation site.Installing plate passes through T-shaped
The cooperation of block and T-slot is realized and substrate is flexibly connected, and is conveniently replaceable with a variety of different reference for installation and mounting hole
Installing plate expands the attachment type in attachment mounting bracket.

Specific embodiment
The utility model is described in further details with reference to embodiment：
As shown in Fig. 1~5, a kind of 8 cylinder Electronic Unit Pump Diesel Engine bodies, including machine main body 1,1 top of machine main body
Two rows of cylinder block 2 of V-shaped arrangement are provided with, cylinder sleeve 3 is installed in two rows of cylinder block 2,2 top of cylinder block passes through with cylinder sleeve 3
