Abstract
The utility model discloses a motor piston, which comprises a gas ring groove and an oil ring groove which are arranged on the surface of the piston body, and a plurality of annular grooves are arranged at the lower position of the oil ring groove on the surface of the piston body. The motor piston has simple structure, prevents the leakage of fuel and improves the efficiency of the motor, which is widely used in motors.
Description
Technical field
The utility model relates to a kind of engine piston.
Background technique
Cylinder and the piston structure in it are because there is the gap in frictional contact surface in existing automobile or the motorcycle engine, being formed with of this gap: behind cylinder bore process bore hole and the endoporus rubbing down, the morpheme cylindricity of endoporus has tolerance range, vapour ring on the piston and oil ring and cylinder bore combine that circumference produces; In addition, because vapour ring and oil ring all are openings, these rings have closed gap again with after cylinder bore cooperates between per pass ring and the cylinder, and these gaps make understands generation gasoline atomizing gas leakage in the acting process, had a strong impact on the stability of power; When adopting liquid gas to make fuel, because of liquid gas is stronger than gasoline atomizing combustion gas seepage, leak even more seriously, compression ratio that is produced and power do not reach engineering design standard at work, cause incomplete combustion, exhaust index instability.
Summary of the invention
In order to overcome the deficiencies in the prior art, it is a kind of simple in structure that the utility model provides, and prevents the engine piston of fuel leak.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of engine piston comprises the vapour annular groove and the oil ring groove that are arranged on the piston body surface, and described piston body surface is positioned at the oil ring groove below and is provided with a plurality of oil storage tanks.
In the utility model, described oil storage tank ringwise.
In the utility model, the quantity of oil storage tank is the 2-12 bar.
In the utility model, oil storage tank is concave point shape.
The beneficial effects of the utility model are: because the utility model is provided with a plurality of oil storage tanks below the piston body surface is positioned at oil ring groove, lubricant oil can be stored in these oil storage tanks like this, in process of manufacture, can further improve the degree of finish of cylinder inner wall, reduced the friction factor between piston and the cylinder inner wall, prevent that product combustion gas when acting from the situation of leaking taking place, reduced the carbon deposit of piston head, stable and increased the compression ratio of firing chamber, improved the power of motor.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is a structural representation of the present utility model;
Fig. 4 is a structural representation of the present utility model.
Embodiment
Referring to figs. 1 through Fig. 4, a kind of engine piston comprises the vapour annular groove 1 and the oil ring groove 2 that are arranged on the piston body surface, and described piston body surface is positioned at oil ring groove 2 belows and is provided with a plurality of oil storage tanks 3.
In the utility model, oil storage tank 3 ringwise.
In the utility model, the quantity of oil storage tank 3 is the 2-12 bar.
In the utility model, oil storage tank 3 is concave point shape.
Because the utility model is provided with a plurality of oil storage tanks 3 below the piston body surface is positioned at oil ring groove 2, lubricant oil can be stored in these oil storage tanks 3 like this, in process of manufacture, can further improve the degree of finish of cylinder inner wall, reduced the friction factor between piston and the cylinder inner wall, prevent that product combustion gas when acting from the situation of leaking taking place, reduced the carbon deposit of piston head, stable and increased the compression ratio of firing chamber, improved the power of motor.
The utility model is simple in structure, prevents fuel leak, has improved the power of motor, is a kind of in-engine engine piston that is widely used in.
