Abstract
The utility model discloses a kind of cast aluminium variable cross-section engine housings, including cylinder head and cylinder body, cylinder head ontology and the cylinder cap being arranged on cylinder head ontology are included on the cylinder head, cooling fin is additionally provided on cylinder head ontology, one end is equipped with the upward raised chamber connected in the cylinder body.The cast aluminium variable cross-section engine housing of the utility model is using cleverly cylinder head and cylinder body are combined, cylinder head thermal diffusivity is good, structure design in cylinder body enables machine oil during use to obtain circulating for maximum dynamics, because machine oil can make it rise to the upper end of raised chamber using kinetic energy to greatest extent when being disturbed by stroke, then machine oil is swept away above raised chamber again comes, to the disturbance of one acceleration of machine oil, and then constantly machine oil is promoted to disturb, it avoids depositing and be greatly prolonged with the usage time for ensureing machine oil, is worthy to be popularized.
Description
Technical field
The utility model belongs to engine manufacturing field more particularly to a kind of cast aluminium variable cross-section engine housing.
Background technology
At present, the case construction of engine is always that common version obtains, tactical rule, and there are babinet inner engine oil is easy
The problem of deposition so that people have to improve the frequency for replacing machine oil, and cost is higher, and waste is big, and people need to find one kind
The engine housing of more preferable structure.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of cast aluminium variable cross-section engine housings.
The utility model is achieved through the following technical solutions：
Cast aluminium variable cross-section engine housing includes cylinder head ontology including cylinder head and cylinder body, on the cylinder head and is arranged on cylinder
Cylinder cap on head ontology, is additionally provided with cooling fin on cylinder head ontology, and one end is equipped with the upward raised chamber of connection in the cylinder body.
Preferably, the cylinder head and cylinder body are split structure.
Preferably, on the cylinder head body outer surface, on the axial direction along cylinder head ontology, it is additionally provided with several and adds
Strong thermal column, the cylinder for strengthening thermal column is in hollow-core construction, and the cooling fin is around the cylinder head ontology and surrounding
Strengthen thermal column.
Preferably, the cooling fin is spiral stream guidance cooling fin, if the spiral stream guidance cooling fin to bending up obliquely
Dry radian, the thickness of the spiral stream guidance cooling fin are gradually thinning on the direction for leaving cylinder head ontology.
Preferably, the cylinder head body exterior is in up big and down small pyramidal structure.
Preferably, several baffles are equipped in the cylinder body.
Preferably, the cylinder body is equipped with fuel feed hole and oil outlet.
The beneficial effects of the utility model are：
The cast aluminium variable cross-section engine housing of the utility model is combined using cleverly cylinder head and cylinder body, cylinder head thermal diffusivity
Good, the structure design in cylinder body enables machine oil during use to obtain circulating for maximum dynamics, because machine oil can rushed
Journey can make it rise to the upper end of raised chamber using kinetic energy to greatest extent when disturbing, and then machine oil is swept away above raised chamber again
Come, to the disturbance of one acceleration of machine oil, and then constantly machine oil is promoted to disturb, avoid depositing to ensure the usage time of machine oil
It greatly prolongs, is worthy to be popularized.
Description of the drawings
For ease of explanation, the utility model is described in detail by following specific embodiment and attached drawing.
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
As shown in Figure 1, cast aluminium variable cross-section engine housing, including cylinder head and cylinder body 1, includes cylinder head ontology on the cylinder head
2 and the cylinder cap 3 that is arranged on cylinder head ontology 2, it is additionally provided with cooling fin 4 on cylinder head ontology 2, one end, which is equipped with, in the cylinder body 1 connects
Logical upward raised chamber 5.
The cylinder head and cylinder body 1 are split structure.
On 2 outer surface of cylinder head ontology, on the axial direction along cylinder head ontology 2, it is additionally provided with several and strengthens heat dissipation
Column, the cylinder for strengthening thermal column are dissipated in hollow-core construction, the cooling fin around the cylinder head ontology and surrounding reinforcement
Plume.
The cooling fin 4 is spiral stream guidance cooling fin, and the spiral stream guidance cooling fin to bending up several radians, institute obliquely
The thickness for stating spiral stream guidance cooling fin is gradually thinning on the direction for leaving cylinder head ontology 2.
2 outside of cylinder head ontology is in up big and down small pyramidal structure.
Several baffles 6 are equipped in the cylinder body 1.
The cylinder body is equipped with fuel feed hole 7 and oil outlet 8.
The cast aluminium variable cross-section engine housing of the utility model is combined using cleverly cylinder head and cylinder body, cylinder head thermal diffusivity
Good, the structure design in cylinder body enables machine oil during use to obtain circulating for maximum dynamics, because machine oil can rushed
Journey can make it rise to the upper end of raised chamber using kinetic energy to greatest extent when disturbing, and then machine oil is swept away above raised chamber again
Come, to the disturbance of one acceleration of machine oil, and then constantly machine oil is promoted to disturb, avoid depositing to ensure the usage time of machine oil
It greatly prolongs, is worthy to be popularized.
The above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
In this, any change or replacement expected without creative work should be covered within the scope of the utility model.
Therefore, the scope of protection of the utility model should be determined by the scope of protection defined in the claims.
