Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail, it is to be understood that this practicality
Novel protection domain is not restricted by specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " comprising " or its change
It changes such as "comprising" or " including " etc. and will be understood to comprise stated element or component, and do not exclude other members
Part or other component parts.
As shown in Figures 1 to 4, according to the cooling water of the Multi-cylinder diesel engine cylinder body of specific embodiment of the present invention
Set is respectively provided with one layer of ring-shaped water jacket 1 around the week of each cylinder 2, and a whole water is connected between the ring-shaped water jacket 1 of each cylinder
Chamber.As a kind of specific embodiment, the arbitrary two cylinders adjacent region of ring-shaped water jacket 12 can be designed as being connected to or not being connected to two kinds of knots
Structure, with the ring-shaped water jacket of two cylinder adjacent regions 12, connectivity structure is not one of example to the present embodiment, and by taking this structure as an example
This programme is described in detail.The bottom of the right side wall of ring-shaped water jacket 1 per cylinder is all provided with there are one water inlet 4, and water inlet 4 is tight
Against the bottom of each cylinder ring-shaped water jacket 1, the shape of water inlet 4 is ellipse.In the present solution, the ring-shaped water jacket of each cylinder
There are one water inlets 4 for corresponding design, it is ensured that the flow uniformity of each cylinder cooling water is reinforced the lateral flow of cooling water, had
Help ensure the cooling effect of each cylinder.The purpose that the shape of water inlet 4 is designed as ellipse is that water jacket water inlet is allowed to lean on as far as possible
Nearly water jacket bottom position, can increase the sectional area of water inlet, you can to increase the inflow of each cylinder, while also having as much as possible
Help reduce casting difficulty.
As shown in Fig. 2, there are multiple upper water holes for leading to cylinder head in the top surface of ring-shaped water jacket 1.Wherein, per cylinder water jacket top surface
Left side is respectively there are two water hole 11 on first, and the cross sectional shape in water hole 11 is triangle on first.Right side per cylinder water jacket top surface is each
There are two water hole 3 on second, the cross sectional shape in water hole 3 is long waist shaped on second.There are one in third for the rearmost end of water jacket top surface
Water hole 9, the cross sectional shape in water hole 9 is elongated kidney-shaped or rectangle structure in third.
Continue as shown in Fig. 2, cylinder periphery has been evenly arranged multiple cylinder bolt hole lugs 18, in order to improve gland shim
Sealing performance and reliability, if clocking requirement as much as possible by cylinder bolt hole lug 18 close to cylinder arrangement, therefore,
The outside corresponding position of 1 top half of ring-shaped water jacket is respectively equipped with arc resigning.Wherein, in two side positions of two cylinder adjacent regions 12
Locate arc 7 (the second inner fovea parts) of big resignings, arc it is big resigning 7 lower section be connected with recessing groove 8 straight down.Except two cylinders are adjacent
Outside the cylinder bolt hole lug 18 of 12 both sides of area, the ring-shaped water jacket at other all cylinder bolt hole lugs 18 has been each provided one
5 (the first inner fovea parts) of a small resigning of arc.After the periphery of ring-shaped water jacket 1 increases arc resigning, in order to ensure the water jacket at resigning
Wall thickness, therefore a vertical arc convex 6 is respectively arranged in the inside at ring-shaped water jacket resigning.
As shown in Figure 2 and Figure 4, sand removal is handled when being cast for the ease of cylinder block, is needed more in ring-shaped water jacket periphery design
A sand cleaning hole.Wherein, there are one front end sand cleaning holes 14 for the front end of water jacket, and also there are one rear end sand cleaning holes 10 for the rear end of water jacket, left
Side shares 3 left side sand cleaning holes 13.The periphery of each sand cleaning hole, is all evenly equipped with 4 technique small boss 16, technique small boss 16
Shape is " u "-shaped or rectangle, is highly 1~4mm.The effect of technique small boss 16 is：When machining each sand cleaning hole, iron
The group of cutting, which disconnects at technique small boss 16 and becomes short and small iron, cuts section, and the formation that iron cuts group can be prevented to throw into inside water jacket,
Facilitate the cleaning (remarks of water jacket inner cavity：When being machined each sand cleaning hole, the iron pin on the inside of sand cleaning hole can be fallen into water-jacket space
Portion, the effect of technique small boss 16 are to allow coarse iron to cut group to become short and small iron and cut section, and short and small iron cuts section than coarse iron
The group of cutting is easy cleaning, reduces cleaning difficulty).
In addition, cylinder block is in process of production, it, be in the annular water of each cylinder because technique needs when making sand core of water jacket
1 lower section 4 areas Ge Shesha 15 of each arrangement of set, the areas She Sha 15 of the left and right side per cylinder water jacket are respectively two, in order to ensure every place
Sand mouth region domain of penetrating there is enough spaces, this programme to devise a cylindric bulge, cylinder in the sand mouth region domain of penetrating at every place
The height of shape bulge is 20~60mm.This programme can be the special jacket structure for water of four-cylinder diesel engine, 1 specific wall thickness of ring-shaped water jacket
Size should determine that, when the discharge capacity of diesel engine is smaller, the average wall thickness of water jacket is got over according to the specification size of specific model
It is small.When the discharge capacity of diesel engine is bigger, the average wall thickness of water jacket is bigger, and the average wall thickness of general ring-shaped water jacket 1 is 5~
12mm.It is fixed for convenience to support the sand core of water jacket in casting, set on right side that there are two use in cylinder of diesel engine cooling jacket
The stud mounting platform 17 of water jacket is fixed in installation stud, two 17 shapes of stud mounting platform are all round, are located at the
Two, third cylinder right positions.
To sum up, the cooling jacket of the Multi-cylinder diesel engine cylinder body of the present embodiment is improved cold by improving the water flow field of water jacket
But uniformity improves the cooling efficiency of cylinder holes periphery water jacket, it is possible to reduce cylinder holes thermal deformation prevents cylinder holes abrasion, piston scraping
Etc. failures, improve the reliability of diesel engine.Cooling jacket uses the arrangement of compact, reduces the volume of cylinder block,
Reduce the main screw lift and its manufacturing cost of diesel engine.
The description of the aforementioned specific exemplary embodiment to the utility model is in order to illustrate and illustration purpose.These
Description is not wishing to for the utility model to be limited to disclosed precise forms, and it will be apparent that according to the above instruction, can carry out
Many change and variations.The purpose of selecting and describing the exemplary embodiment is that explaining the specific principle of the utility model
And its practical application, so that those skilled in the art can realize and utilize a variety of different examples of the utility model
Property embodiment and various chooses and changes.The scope of the utility model is intended to by claims and its waits similar shapes
