Description
Technical field
The utility model relates to a kind of piston assembly, particularly a kind of internal combustion engine assembly.
Background technique
It is " maincenter " of motor that piston can be understood as, except being in abominable working environment, in it or the motor the most busy one, constantly carrying out to-and-fro motion up and down, there are three piston ring grooves at the skirt body place of each piston, for the twice compression ring being installed with oil ring, and compression ring at upper oil ring lower.When assembling, the opening of twice compression ring need to stagger, and plays the effect of sealing.The effect of oil ring mainly is to strike off the unnecessary lubricant oil that is splashed on the casing wall, and the lubricant oil sheaing is even.
Piston ring is a kind of metallic elastic ring with the distortion of expanding outwardly, and compression ring is when work, owing to being subjected to the impact of high temperature, high pressure, poor lubrication, its wearing and tearing are very fast, the elastic force of compression ring also weakens along with wearing and tearing, and the gap between compression ring and the piston wall will increase, and has affected the sealing of compression ring.
For efficient energy-conservation and the raising internal-combustion engine, people have done a lot of improvement to piston, have in the patent at present and disclose the efficient that improves internal-combustion engine at 2 piston rings of a piston ring groove general assembly, but it can not reach best effect, does not satisfy existing people to the demand of the efficient of energy-conservation and raising internal-combustion engine.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of internal combustion engine assembly that improves the efficiency of internal combustion engine, good energy-conserving effect is provided.
The technological scheme that solves the problems of the technologies described above is: a kind of internal combustion engine assembly, comprise piston body and piston ring, offer compression I and compression II on the described piston body, described piston ring is installed in respectively in compression I and the compression II, offer an opening on this piston ring, the width A of described compression II is 4 times of compression I width B.
Further technological scheme of the present utility model is: an end of the opening on the described piston ring has seal recess, and the other end of this opening is provided with the sealing flange that is complementary with seal recess.
Described piston ring comprises the compression ring I that is complementary with the compression I and the compression ring II that is complementary with the compression II.
The cylindrical of described compression ring II is the concentric step circle that is connected with a roundlet by a great circle.
The thickness of described great circle and roundlet is respectively half of whole compression ring II thickness H.
Because adopt technique scheme, the internal-combustion engine piston assembly of the utility model has following beneficial effect:
1. the utility model comprises piston body, offer compression I and compression II on the described piston body, the width of described compression II is 4 times of compression I width, can be so that compression ratio has increased by 7 times, can make the power of internal-combustion engine obviously improve 40%, save 40% oil mass.And the increase along with compression II width, the thickness that is installed in the compression ring in this compression II also needs to increase to some extent, perhaps also several compression rings can be installed in this compression II more, thereby can reduce the wearing and tearing of compression ring, prevent weakening of compression ring elastic force, improve the sealing of compression ring, increased the working life of piston, thereby reached well energy-conservation efficient with improving internal-combustion engine.
2. an end of the opening on the piston ring in the utility model has seal recess, the other end of this opening is provided with the sealing flange that is complementary with seal recess, thereby can better improve the tightness of piston ring, and the cylindrical of the compression ring II that comprises in the piston ring concentric step circle that to be a great circle be connected with a roundlet, piston is when work, only have great circle to contact with the gas wall, area of contact has reduced, in the situation that piston ring elasticity is identical, piston ring has increased the pressure of cylinder wall, thereby so that the airtight effect of piston is better, has also improved the efficient of internal-combustion engine, conserve energy, reduced cost, the utility model is convenient to promote the use of.
Below, be further described in conjunction with Figure of description and the specific embodiment technical characteristics to the internal-combustion engine piston assembly of the utility model.
