Description
Technical field
The utility model is related to a kind of engine section variable box bodies.
Background technology
At present, the case construction of engine is always common version, due to the friction of stroke head and cylinder head, unavoidably
It can generate some impurity, and these impurity enter in machine oil machine oil can be caused muddy, the permanent smooth movement of different engine,
In addition, as environmental requirement is increasingly strict, it is desirable to use small automobile that can have big power, existing engine can not yet
Meet, people need to find a kind of 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 engine section variable box bodies.
The utility model is achieved through the following technical solutions：
Engine section variable box body, including cylinder head, cylinder body, bent axle, connecting rod and stroke head, the stroke head is arranged on cylinder
In head, cooling fin is equipped on the outside of the cylinder head, the cylinder head top is connected with air inlet pipe and outlet by air inlet and gas outlet
Pipe, the area of section of the gas outlet is bigger than the area of section of air inlet, and the cylinder base is equipped with a recessed portion, the recess
Subordinate end is equipped with outage, among the recessed portion, above outage, is additionally provided with a circle catch.
Preferably, the cylinder head and cylinder body are split structures.
Preferably, the cooling fin helically structure.
Preferably, cooling water flow conduits are additionally provided in the cylinder head wall body for same cooling water.
Preferably, the engine section variable box body is cast aluminium material.
The beneficial effects of the utility model are：
The utility model clever structure by setting cooling fin, can radiate well for cylinder head, improve safety, prolong
Long life；Gas outlet area of section is bigger than air inlet, can increase capacity, accelerates exhaust velocity, and exhaust is more clean,
And then can air inlet is more smooth, air inlet is more, more often, burning can be more abundant, conducive to increasing for the fresh oxygen in cylinder head
Add power, be also conducive to improve the feature of environmental protection of tail gas；And recessed portion is equipped in cylinder base, a circle catch is equipped among recessed portion,
The impurity that can be used for the cylinder head for blocking and cylinder body friction generation is not disturbed back and forth, conducive to machine oil in use is kept
Cleanliness factor makes engine operation more smooth.
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, engine section variable box body, described including cylinder head 1, cylinder body 2, bent axle 3, connecting rod 4 and stroke head 5
Stroke head 5 is arranged in cylinder head 1, and 1 outside of cylinder head is equipped with cooling fin 6, and 1 top of cylinder head passes through air inlet 7 and outlet
Mouth 8 is connected with air inlet pipe and air outlet pipe, and the area of section of the gas outlet 8 is bigger than the area of section of air inlet 7, the cylinder body 2
Bottom is equipped with a recessed portion 9, and 9 lower end of recessed portion is equipped with outage 10, among the recessed portion 9,10 top of outage, also
Equipped with a circle catch 11.
The cylinder head 1 and cylinder body 2 are split structures.
The cooling fin 6 helically structure.
Cooling water flow conduits 12 are additionally provided in 1 wall body of cylinder head for same cooling water.
The engine section variable box body is cast aluminium material.
The utility model clever structure by setting cooling fin, can radiate well for cylinder head, improve safety, prolong
Long life；Gas outlet area of section is bigger than air inlet, can increase capacity, accelerates exhaust velocity, and exhaust is more clean,
And then can air inlet is more smooth, air inlet is more, more often, burning can be more abundant, conducive to increasing for the fresh oxygen in cylinder head
Add power, be also conducive to improve the feature of environmental protection of tail gas；And recessed portion is equipped in cylinder base, a circle catch is equipped among recessed portion,
The impurity that can be used for the cylinder head for blocking and cylinder body friction generation is not disturbed back and forth, conducive to machine oil in use is kept
Cleanliness factor makes engine operation more smooth.
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.
