Secondly, said body is provided with back oil road, and said back oil road is arranged on the both sides of said cylinder barrel.
Further, be provided with the stiffening plate that extends below perforation in the said back oil road.
Secondly, many stiffening ribs that connect before and after the both sides of said body are equipped with.
Once more, said rear end flanged surface is connected through the inclined-plane with the both sides sidewall of said body.
Further, said rear end flanged surface is provided with many radial stiffening ribs.
Further, said rear end flanged surface is provided with a plurality of going and heavily cheats.
Wherein, the top of said water jacket is a closing structure.
Secondly, said engine cylinder-body is six-in-line formula engine cylinder-body or eight cylinder type engine cylinder bodies in upright arrangement.
The engine cylinder-body that the utility model embodiment provides; With said correct time chamber, water supply water channel and water pump spiral case all be integrated on the body of engine cylinder-body, make engine structure compacter, resistance to shock improves; Especially said water supply water channel is integrated on the said body; Rather than introduction pipe is as the water supply water channel in addition, and wherein, the shell of said water supply water channel has further been reinforced the join strength between crankcase and cylinder barrel.

Embodiment
Below in conjunction with accompanying drawing the utility model embodiment engine cylinder-body is described in detail.
Should be clear and definite, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making all other embodiments that obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Like Fig. 1, Fig. 4, Fig. 5 and shown in Figure 6, the engine cylinder-body that the utility model embodiment provides comprises body; Be provided with a plurality of cylinder barrels 1 in the said body and around the water jacket 4 of cylinder barrel 1; Wherein, the integrated water supply water channel in flanged surface chamber in 11 integrated correct time 6, right side 3, the integrated water pump spiral case 2 of front end in the rear end of said body, and as shown in Figure 3; The right sidewall of said body is provided with the water intake 20 of water jacket 4, and the inlet of water supply water channel 3 connects the water intake 20 of water pump spiral case 2, outlet connection water jacket 4.
The engine cylinder-body that the utility model embodiment provides; With said correct time chamber, water supply water channel and water pump spiral case all be integrated on the body of engine cylinder-body, make engine structure compacter, resistance to shock improves; Especially said water supply water channel is integrated on the said body; Rather than introduction pipe is as the water supply water channel in addition, and wherein, the shell of said water supply water channel has further been reinforced the join strength between crankcase and cylinder barrel.
Referring to Fig. 1, Fig. 2 and shown in Figure 3, said body is provided with back oil road 5, and back oil road 5 is arranged on the both sides of cylinder barrel 1.The both sides that said back oil road is arranged on said cylinder barrel more help oil return and ventilation, because when motor tilt to be installed, low side back oil road is used for oil return, and a higher side back oil road is used for ventilating, and when satisfying oil return, ventilation effect is better; If motor is not when tilting installation, oil return simultaneously of the back oil road of both sides and ventilation, it is better that oil return and ventilation effect also can only be provided with back oil road in a side.
As shown in Figures 2 and 3, be provided with the stiffening plate 7 that extends below perforation in the back oil road 5.Because the position of said back oil road and the position of main bearing seat are corresponding, and the rigidity that said stiffening plate can improve main bearing seat is set in said back oil road.
As shown in Figures 2 and 3, many stiffening ribs 10 that connect before and after the both sides of said body are equipped with.The stiffening rib that said front and back connect matches with said back oil road engine cylinder-body is divided into a plurality of cell cubes, has improved the rigidity and the intensity of engine cylinder-body, has effectively improved resistance to shock, has reduced noise and risk of distortion.
Referring to shown in Figure 1, rear end flanged surface 11 is connected through inclined-plane 12 with the both sides sidewall of said body once more.Since between the both sides of said rear end flanged surface and said body join strength a little less than; Generally need reinforcement; Common way is the welding stiffening rib; Can further improve join strength and directly the two is made integral body through ramp structure, simultaneously also can with the body integrally casting moulding of engine cylinder-body, technology is simple.
As shown in Figure 6, rear end flanged surface 11 is provided with many radial stiffening ribs 9.Thereby said radial stiffening rib can improve the rigidity of rear end flanged surface and improve anti-seismic performance, and flanged surface can also be provided with and a plurality ofly go heavily to cheat 8 in the rear end simultaneously, is used for reducing because the weightening finish problem of the said body that the said stiffening rib of welding causes.
As shown in Figure 4, the top of water jacket 4 is a closing structure.The top of existing technology water jacket generally is continuous structure, can reduce the intensity at cylinder body top like this, causes the cylinder barrel easy deformation, and the top design of water jacket is become discontinuous enclosed construction, can overcome the problems referred to above.
To the foregoing description, said engine cylinder-body can be six-in-line formula or eight cylinder type engine cylinder bodies in upright arrangement.
The above; Be merely embodiment of the present invention, but protection scope of the present invention is not limited thereto, any technician who is familiar with the present technique field is in the technical scope that the present invention discloses; Can expect easily changing or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of said claim.
