Abstract
A cylinder body and cylinder cover connecting structure of an automobile engine comprises a cylinder body with a water jacket, a cylinder cover, a cylinder gasket and a cylinder cover bolt and is characterized in that the cylinder gasket is arranged at the sealing position, where the cylinder body and the cylinder cover are connected; a cylinder body threaded hole for connecting with the cylinder cover bolt on the cylinder body extends deeply to the lower-end position of the bottom of the water jacket of the cylinder body. The present engine cylinder body, the cylinder cover, the cylinder cover bolt are utilized and the cylinder cover bolt is lengthened; meanwhile, the corresponding cylinder body threaded hole is lengthened and the cylinder cover bolt is screwed up to the high-rigidity position at the lower end of the bottom of the water jacket of the cylinder body, so that the screwing deformation of the cylinder hole is reduced. The cylinder body and cylinder cover connecting structure of the automobile engine has the advantages of simple and rational structure, long service life, safety and reliability and wide application range and the like.
Description
Technical field
The invention belongs to technical field of automobile engine, specifically the linkage structure of a kind of automobile engine cylinder body and cylinder cap.
Background technique
At present, in order to reduce the frictional loss of engine running, taking the piston ring of low-tension, causing consumption of lubricating oil also in rising trend.Main cause is: tension force is low subtract after, the following of piston ring to cylinder-bore also declines simultaneously, and cylinder-bore due to thermal distortion and cylinder bolt screwing force impact and produce distortion.The two compares, and the amount of deformation of thermal distortion is relatively a little bit smaller, and it is then larger to tighten distortion.In the past when on engine cylinder cover bolt tightening to cylinder block, it is the position, top being tightened to cylinder block, the stress of such cylinder bolt screw section can pass to cylinder-bore through cylinder block upper wall, cause cylinder-bore distortion to increase, therefore how to suppress to tighten the key that distortion is reduce engine oil consumption and air leakage.
Summary of the invention
The object of this invention is to provide and a kind ofly reduce the automobile engine cylinder body of cylinder-bore distortion amount and the linkage structure of cylinder cap.
The object of the present invention is achieved like this, it comprises the cylinder block with water jacket, cylinder head, head gasket, cylinder head bolt, it is characterized in that: described head gasket is arranged on the sealing station that cylinder block is connected with cylinder head, and the cylinder block thread hole depth for connecting cylinder head bolt in cylinder block extends to the position of lower end bottom block jacket.
Specifically, described cylinder block thread hole depth extends on the position that bottom block jacket, lower end rigidity is high, is out of shape and reduce engine oil consumption and air leakage to suppress to tighten.
The present invention utilizes available engine cylinder block, cylinder head, cylinder head bolt, extended by cylinder bolt, meanwhile, corresponding cylinder block thread hole also extends, cylinder bolt is tightened on the position that bottom block jacket, lower end rigidity is high, thus reduce cylinder-bore tighten distortion.
The technical solution adopted in the present invention comprises the cylinder bolt and the cylinder block that also extends of corresponding tapped hole that design one lengthens, together with cylinder head is securely fixed in cylinder block by the cylinder bolt of lengthening.
This is novel also have simple and reasonable, long service life, safe and reliable, the advantages such as application area is wide.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 be in Fig. 1 B-B to cross-sectional view;
Fig. 3 be in Fig. 1 A-A to cross-sectional view.
The symbol description of accompanying drawing major component
1-cylinder head, 2-cylinder block, 3-head gasket, 4-cylinder head bolt, 5-block jacket.
Be described in further detail the present invention by example below in conjunction with accompanying drawing, but following example is only the present invention's example wherein, do not represent the right protection scope that the present invention limits, the scope of the present invention is as the criterion with claims.
Embodiment
example 1
As shown in Figures 1 to 3,1 in figure is cylinder head, and 2 is cylinder block, and 3 is head gasket, and 4 is cylinder head bolt, and 5 is block jacket; Described head gasket 3 is arranged on the sealing station that cylinder block 2 is connected with cylinder head 1, and the cylinder block thread hole depth for connecting cylinder head bolt 4 in cylinder block 2 extends to the position that bottom block jacket 5, lower end rigidity is high.
Structure of the present invention is simple, through installation test: consumption of lubricating oil has obvious reduction in 3000 ~ 4000rpm scope, and other speed range effect slightly well; Low to subtract effect better at 2000 ~ 4500rpm for air leakage.
Claims (2)
1. the linkage structure of an automobile engine cylinder body and cylinder cap, it comprises the cylinder block with water jacket, cylinder head, head gasket, cylinder head bolt, it is characterized in that: described head gasket is arranged on the sealing station that cylinder block is connected with cylinder head, and the cylinder block thread hole depth for connecting cylinder head bolt in cylinder block extends to the position of lower end bottom block jacket.
2. a linkage structure for automobile engine cylinder body and cylinder cap, is characterized in that: described cylinder block thread hole depth extends on the position that bottom block jacket, lower end rigidity is high.
