Description
Technical field
This utility model relates to piston combustion bowl technical field, is specifically related to a kind of piston of automobile engine combustor and vapour
Car.
Background technology
The piston of automobile engine chamber structure that presently, there are, including head valve room and top land, wherein piston
Top structure determines the shape of combustor to a certain extent, also determines the fired state of electromotor.The work of prior art
Plug combustor, also exists burning problem uneven, inefficient.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of piston of automobile engine combustor and automobile, can solve
Certainly burn problem uneven, that efficiency of combustion is low.
For solving above-mentioned technical problem, the piston of automobile engine combustor that this utility model provides includes: head valve
Room and top land, described top land includes the first end face and the second end face, in the centre position shape of described first end face
Become to have top pit, be formed around air inlet valve pit and aerofluxus valve pit at described top pit；Wherein, described piston top
The maximum of the thickness in portion is between 8.4～8.6mm.
Preferably, the end, hole of described air inlet valve pit to the distance of the second end face between 2.1～2.2mm.
Preferably, the end, hole of described aerofluxus valve pit to the distance of the second end face between 2.6～2.7mm.
This utility model additionally provides a kind of automobile, including above-described piston of automobile engine combustor.
Compared with prior art, a kind of piston of automobile engine combustor of this utility model offer and automobile, at least have
There is a following beneficial effect:
This utility model can improve efficiency of combustion, in Tumble and swirl, tubulence energy and flame propagation velocity, deflagrating jar voltage crest
Further effect of optimization is obtained in the projects such as value, heat liberation rate, heat release rate speed.
Accompanying drawing explanation
The top view of the piston of automobile engine combustor that Fig. 1 provides for this utility model embodiment；
Fig. 2 provides the side view of piston of automobile engine combustor for this utility model embodiment.
Detailed description of the invention
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And specific embodiment is described in detail.
This utility model embodiment provides a kind of piston of automobile engine combustor, this piston of automobile engine combustor
Including: head valve room and top land.Wherein, as shown in Fig. 1～2, described top land includes the first end face 1 and second
End face 2, is formed with top pit 3 in the centre position of described first end face 1, described top pit 3 be formed around into
Gas valve pit 4 and aerofluxus valve pit 5；Wherein, the maximum of the thickness of described top land is between 8.4～8.6mm.
Here, during the design of air inlet valve pit 4 and aerofluxus valve pit 5 makes piston movement, meet and head valve
Having rational clearance requirement, top pit 3 beneficially combustion mixture is formed and burns and regulate engine compression ratio.
Preferably, the end, hole of described air inlet valve pit 4 to the distance of the second end face between 2.1～2.2mm.
Preferably, the end, hole of described aerofluxus valve pit 5 to the distance of the second end face between 2.6～2.7mm.
This utility model embodiment additionally provides a kind of automobile, including above-described piston of automobile engine combustor.
Fig. 2 furthermore present a concrete example of the structural parameters of top land of the present utility model, such as Fig. 2 institute
Show:
The maximum of the thickness of described top land is 8.5mm.
Preferably, the end, hole of described air inlet valve pit 4 is 2.15mm to the distance of the second end face.
Preferably, the end, hole of described aerofluxus valve pit 5 is 2.63mm to the distance of the second end face.
After above-mentioned improvement, the piston combustion bowl that this utility model embodiment provides is at Tumble and swirl, tubulence energy and flame
It is further enhanced in the projects such as spread speed, deflagrating jar voltage crest value, heat liberation rate, heat release rate speed, fires through the piston with prior art
Burning room to test and contrast, after finding to use this utility model structure, Tumble and swirl brings up to 1.68 from 1.56, in-cylinder tumble flow
Respond well, the distribution of tubulence energy maximum is improved, and in cylinder, ignition is fast, and heat liberation rate, heat release rate improves, and it is more uniform that flame propagates ratio.
The above is preferred implementation of the present utility model, it is noted that for the ordinary skill of the art
For personnel, on the premise of without departing from principle described in the utility model, it is also possible to make some improvements and modifications, these improve
Also protection domain of the present utility model is should be regarded as with retouching.
