Technical field
The present invention relates to field of internal combustion engine, particularly to a kind of body of internal combustion engine.
Background technology
Usually, the body cylinder holes of traditional combustion engine and cylinder sleeve are usually dynamic cooperation or interference fits load body, cylinder sleeve
Outer surface is not contacted with cooling water, therefore no-cooling-water sealing problem.In cylinder jacket, the sealing between part and cylinder head is by cylinder
Set and cylinder pad pressurized formation band.
In the prior art scheme, shoulder of cylinder liner width little it is desirable to there be bulge quantity just can have good sealing, to cylinder pad will
Ask high, and convex shoulder is pressurized big, is easily broken off, cylinder pad is easily washed out by combustion gas.Convex shoulder and body same plane, sealing is fair, but work
Skill requires strictly, and cylinder pad is easily washed out by combustion gas.During the Cylinder sticking of cylinder sleeve lower end, cylinder sleeve axial displacement may be caused, make cylinder-liner distortion.
The information being disclosed in this background section is merely intended to increase the understanding of the general background to the present invention, and should not
Recognize when being considered or imply in any form that this information structure has been the prior art well known to persons skilled in the art.
Content of the invention
It is an object of the invention to provide a kind of body of internal combustion engine, it is to avoid cylinder pad is washed out by combustion gas.
For achieving the above object, the invention provides a kind of body of internal combustion engine, including：Cylinder block, this cylinder block has
Organism cylinder holes portion；Cylinder head, this cylinder head has cylinder cap cylinder holes portion, and cylinder head is fixedly mounted in cylinder block, machine body cylinder
The cylinder holes of the body of hole portion and cylinder cap cylinder holes portion combination formation internal combustion engine, the joining place in machine body cylinder hole portion and cylinder cap cylinder holes portion has
Locating slot；And cylinder jacket, it is used for being arranged in cylinder holes, and the outer wall of the middle part of cylinder jacket is provided with shoulder, shoulder with
Locating slot coordinates.
Preferably, cylinder jacket and the matching part in cylinder cap cylinder holes portion are interference fit, and cylinder jacket is joined with machine body cylinder hole portion
Close position to coordinate for gap.
Preferably, the inner side of machine body cylinder hole portion is provided with damping trough, and this damping trough is used for installing rubber ring.
Preferably, the number of damping trough is two.
Compared with prior art, the present invention has the advantages that：Body is cooperatively formed by cylinder block and head
Cylinder holes, cylinder jacket is partly installed in cylinder head, is partly installed in cylinder block under cylinder jacket, and the support of cylinder jacket is convex
Shoulder (shoulder) is located at the centre position of cylinder jacket, without cylinder pad, therefore does not exist and rushes cylinder pad problem.And solve cylinder jacket and add
The problem of work, body casting and processing technology difference.
Brief description
Fig. 1 is the structural representation of the body of the internal combustion engine according to the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings, the specific embodiment of the present invention is described in detail, it is to be understood that the guarantor of the present invention
Shield scope is not limited by specific embodiment.
Explicitly indicate that unless otherwise other, otherwise in entire disclosure and claims, term " inclusion " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other units
Part or other part.
As shown in figure 1, a kind of body of the internal combustion engine according to the specific embodiment of the invention, including cylinder block 2, cylinder head
1 and cylinder jacket 3, this cylinder block 2 has machine body cylinder hole portion, this cylinder head 1 has cylinder cap cylinder holes portion, cylinder head 1 is fixing
Be arranged in cylinder block 2, machine body cylinder hole portion and cylinder cap cylinder holes portion combination formed internal combustion engine body cylinder holes, machine body cylinder hole portion and
The joining place in cylinder cap cylinder holes portion has locating slot (position with shoulder 31 cooperation), and cylinder jacket 3 is used for being arranged in cylinder holes, cylinder
The outer wall of the middle part of set 3 is provided with shoulder 31, shoulder 31 and locating slot cooperation.
In such scheme, the body of internal combustion engine is formed by cylinder block and head segmented fit system, and top is divided into
Cylinder head 1, bottom is divided into cylinder block 2, and middle is cylinder jacket 3, and cylinder jacket 3 is partly installed in cylinder head 1, cylinder jacket 3
Under be partly installed in cylinder block 2, the support convex shoulder (shoulder 31) of cylinder jacket 3 is located at the centre position of cylinder jacket 3, without cylinder
Pad, therefore do not exist and rush cylinder pad problem.In processing, cylinder head 1 pushes up bottom distance by controlling the platform of cylinder jacket 3 with cylinder jacket 3
Shoulder 31 and the size of locating slot to be adjusted, during solution Cylinder sticking, cylinder jacket 3 axial displacement problem and machining cylinder block manufacturability issues.
And, no water cavity around the cylinder holes of the body of this internal combustion engine, this makes body casting technique simplify, and strengthens the intensity of body, subtracts
Little cylinder centre line spacing, reduces body weight.
As a kind of preferred embodiment, cylinder jacket 3 is interference fit with the matching part in cylinder cap cylinder holes portion, cylinder jacket 2 with
The matching part of machine body cylinder hole portion coordinates for gap.In this programme, part and the joining of cylinder cap cylinder holes portion on the shoulder of cylinder jacket 3
It is combined into interference fit, under the shoulder of cylinder jacket 3, part and machine body cylinder hole portion coordinate for gap, can improve cylinder head high-temperature region
Heat-sinking capability.
As a kind of preferred embodiment, the inner side of machine body cylinder hole portion is provided with damping trough 21, and this damping trough 21 is used for installing rubber
Cushion rubber.In this programme, due to coordinating for gap between cylinder block 2 and cylinder jacket 3, therefore it is located at lower end and is provided with damping trough 21, subtract
It is equipped with O-shaped rubber ring in shake groove 21.When descent of piston, partly there is side force under cylinder jacket, this damping trough 21 can have
Imitate prevents the periodic alternate stress of cylinder jacket 3, prevents the fatigue rupture of cylinder jacket 3.
As a kind of preferred embodiment, the number of damping trough 21 is two.
To sum up, the body of the internal combustion engine of the present embodiment, cooperatively forms body cylinder holes, cylinder by cylinder block 2 and cylinder head 1
It is partly installed in cylinder head 1 on set 3, be partly installed under cylinder jacket 3 in cylinder block 2, the support convex shoulder of cylinder jacket 3
(shoulder 31) is located at the centre position of cylinder jacket 3, without cylinder pad, therefore does not exist and rushes cylinder pad problem.And solve cylinder jacket and add
The problem of work, body casting and poor in processability.
The description of the aforementioned specific illustrative embodiment to the present invention illustrate that and illustration purpose.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can much be changed
And change.The purpose of selecting and describing the exemplary embodiment is that explaining that the certain principles of the present invention and its reality should
With so that those skilled in the art be capable of and utilize the present invention various different exemplary and
