Technical field
The utility model relates to diesel engine manufacturing technologies, and in particular to a kind of diesel engine cylinder block.
Background technique
Diesel engine is extremely complex movable machinery, and externally output acting is that diesel oil is burnt in the combustion chamber by thermal energy turn
Kinetic energy is turned to, is carried out by conversion with crankshaft with rotated versions.Combustion chamber be by piston, cylinder cap, cylinder sleeve, Piston volume tube at
, it is a relatively closed space, behind diesel oil spirt combustion chamber, diesel combustion makes gas expansion in combustion chamber, to push
Piston moves up and down in cylinder sleeve, by the thermal energy after burning at the kinetic energy of piston up-down.Piston is upper and lower in cylinder sleeve
Movement, the sealing between them is a few road piston rings by being mounted on piston crown.Diesel engines at present cylinder body has the following defects,
It is not provided with cooling heat radiation system, cooling and cooling effect is bad, and durability is poor, and service life is short, these defects seriously limit
The further development of diesel engine cylinder block.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies of the prior art and provide a kind of cooling and cooling effect
Good, durability is good and diesel engine cylinder block with long service life.
In order to solve the above technical problems, the utility model uses following technical scheme:
A kind of diesel engine cylinder block, including ontology, reinforcing exterior ring cap and thermal insulation layer, the ontology are arranged to Y type ring body structurc,
The periphery for reinforcing exterior ring cap and being sheathed on the ontology, the periphery of the outer peripheral surface for reinforcing exterior ring cap and the bodies top
Face is coplanar, is connected with connection ring, the reinforcing exterior ring cap, the connection between the bottom end and the ontology for reinforcing exterior ring cap
Ring and the ontology are enclosed closed cooling space, and the thermal insulation layer fitting sle is fixed in the periphery for reinforcing exterior ring cap
Wall is respectively equipped with cool-air device and aspirator in the right side side of the ontology and left side side on the outer wall of the thermal insulation layer, it is described plus
Gu exterior ring cap and the thermal insulation layer are equipped with interconnected perforation wind path, the cool-air device and the aspirator pass through institute respectively
It states perforation wind path and is connected to the cooling space.
As a further improvement of the above technical scheme:
The top fitting sle of the thermal insulation layer is fixed in the ontology.
High silica wool or super glass wool are folded in the thermal insulation layer.
Compared with the prior art, the advantages of the utility model are:
The diesel engine cylinder block of the utility model includes that ontology, reinforcing exterior ring cap and thermal insulation layer, the ontology are arranged to Y type ring
Body structure, the periphery for reinforcing exterior ring cap and being sheathed on the ontology, the outer peripheral surface for reinforcing exterior ring cap and the ontology top
The outer peripheral surface in portion is coplanar, is connected with connection ring between the bottom end and the ontology for reinforcing exterior ring cap, the reinforcing exterior ring cap,
The connection ring and the ontology are enclosed closed cooling space, and the thermal insulation layer fitting sle is fixed in the reinforcing exterior ring cap
Periphery wall, be respectively equipped with cool-air device and aspirator in the right side side of the ontology and left side side on the outer wall of the thermal insulation layer,
Exterior ring cap and the thermal insulation layer reinforced is equipped with interconnected perforation wind path, the cool-air device and aspirator difference
The cooling space is connected to by the perforation wind path.The diesel engine cylinder block of the structure has cool-air device and aspirator, cold wind
Device is used to be sent into cold wind to cooling space, accelerates the cooling of ontology, and the hot-air of aspirator extraction cooling space accelerates cooling
The circulation of hot and cold air in space, further increases the cooling velocity of ontology, so that extend the durability and service life of ontology；
Also have and reinforce exterior ring cap, further increases durability.
Detailed description of the invention
Fig. 1 is the schematic cross-sectional view of the utility model diesel engine cylinder block.
Each label indicates in figure:
1, ontology；2, exterior ring cap is reinforced；21, connection ring；3, thermal insulation layer；4, cooling space；5, cool-air device；6, aspirator；

Specific embodiment
Below with reference to the attached drawing of the utility model, the technical solution of the utility model embodiment is described in detail, is shown
So, described embodiment is only the embodiment of the utility model a part, instead of all the embodiments, practical based on this
Novel embodiment, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, fall within the protection scope of the utility model.
As shown in Figure 1, the diesel engine cylinder block of the present embodiment, including ontology 1, reinforcing exterior ring cap 2 and thermal insulation layer 3, ontology 1 are set
It is set to Y type ring body structurc, reinforces the periphery that exterior ring cap 2 is sheathed on ontology 1, reinforces 1 top of outer peripheral surface and ontology of exterior ring cap 2
Outer peripheral surface is coplanar, reinforces between the bottom end and ontology 1 of exterior ring cap 2 and is connected with connection ring 21, reinforces exterior ring cap 2,21 and of connection ring
Ontology 1 is enclosed closed cooling space 4, and 3 fitting sle of thermal insulation layer is fixed in the periphery wall for reinforcing exterior ring cap 2, thermal insulation layer 3 it is outer
