Abstract
At present, problems exist during the operating process of the internal combustion engine of an automobile, and the prior piston used in an automobile engine has the disadvantages that because one piston gas ring is positioned in one gas ring groove, the friction is increased, the opening of the gas ring is expanded, gas leakage occurs, the fuel consumption of the automobile is high because of oil use, power is insufficient, and the exhaust emissions are high. The utility model relates to a sealing piston of an internal combustion engine, which can solve the problems. Two gas rings are installed in one gas ring groove of the piston; the openings are symmetrically installed; when gas leaks downwards via the opening above, a closed surface is arranged below; the gas can not leak; and at the same time, the oil cannot jump into the combustion chamber. Therefore, the oil for the automobile can be saved, the power is increased, and the exhaust gas pollution can be reduced.
Description
Technical field
The utility model belongs to a kind of sealed member of internal-combustion engine.
Background technique
At present, in car industry, train industry, steamer industry, there are some problems in the internal-combustion engine of use.Car combustion engine exists oil consumption big, and exhaust emissions is many, and power is low etc.Reason is the piston of automobile of existing use, places a compression ring in the compression, and along with friction increases, the opening of compression ring increases gradually, causes gas leakage, burn oil.
Summary of the invention
The purpose of this utility model is the generation for fear of above-mentioned situation, and has designed sealing piston of internal-combustion engine.
It is made up of three parts, first portion is on the basis of the specification of former piston, quality, and the piston gas ring groove is widened one times, and two compression rings are arranged in each compression of second portion, third part two compression ring openings when mounted wants symmetry to install, and can seal the compression ring opening mutually.When gas from top to down the time, gas is a sealing surface below after breaking through from top compression ring opening, does not go under the gas, has increased the sealing of firing chamber gas.When machine oil from bottom to top the time, after machine oil is broken through from following compression ring opening, above the lower end surface of compression ring be sealing surface, machine oil is scurried less than in the firing chamber, burn oil reduces, the pollution emission of automobile reduces, their advantage has: 1, improve the piston of automobile sealing; 2, increase automobile power; 3, reduce automobile fuel consumption; 4, reduce motor vehicle exhaust emission and reduce pollution.
Description of drawings
The utility model is described in further detail below in conjunction with the embodiment of accompanying drawing.
Fig. 1 is the sealing piston of internal-combustion engine structural drawing, (1) is piston body, (2), (3), (4), (5) are piston gas rings, (6) be that oil piston ring, (7), (8) are the piston gas ring grooves, (9) be the piston oil annular groove, two piston gas rings are respectively placed in plug cock compression (7), (8), and the placement of the opening of compression ring symmetry, differ 180 degree.
Embodiment
The purpose of this utility model is to implement like this, and when machining piston body (1), compression is widened to a times of original size, places two compression rings in the compression ring groove, and when compression ring was installed, two opening symmetries differed 180 degree.
Claims (4)
1, the packed-piston that is used for internal-combustion engine is characterized in that placing in the compression two piston gas rings, and it is by piston body (1), piston gas ring (2), (3), (4), (5), and oil piston ring (6), compression (7), (8), oil ring groove (9) is formed.
2, sealing piston of internal-combustion engine as claimed in claim 1 is characterized in that piston gas ring groove (7), (8), and well width is widened one times.
3, sealing piston of internal-combustion engine as claimed in claim 1 is characterized in that placing two compression rings in the piston gas ring groove (7), places two compression rings in the compression (8).
4, sealing piston of internal-combustion engine as claimed in claim 1 is characterized in that two compression ring opening symmetries in the compression are placed, and opening differs 180 degree.
