Abstract
The utility model discloses an airtight piston for piston type diesel oil and gasoline engine, which is related to improvement of piston structure for piston type diesel oil, gasoline engine. The utility model provides an airtight piston for piston type diesel oil, gasoline engine to reduce air leak of piston. The utility model comprises a piston, a key point of the structure is that two piston rings with staggered opening are arranged in each air ring groove on the piston.
Description
Technical field:
The utility model relates to piston type diesel oil, petrolic structure of piston is improved.
Background technique:
At present, be provided with a piston ring in the compression of piston type diesel oil, petrolic piston with opening.Piston is when work, and the gas in the cylinder is partly discharged from opening, and especially when piston wear was big, the gas of discharge was more, has influenced efficiency of engine.
The model utility content:
The utility model is exactly at the problems referred to above, and a kind of piston type diesel oil of blow-by of piston, petrolic air tight piston of reducing is provided.
The utility model adopts following technological scheme: the utility model comprises piston, is provided with the piston ring that two openings stagger in each compression on its structure outline piston.
The beneficial effects of the utility model:
Owing to be provided with the piston ring that two openings stagger in each compression on the piston, therefore, just can effectively avoid gas to overflow from the piston opening, improve efficiency of engine.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a piston structure schematic representation of the present utility model;
Fig. 3 is the structural representation of piston ring of the present utility model.
Embodiment:
The utility model comprises piston 5, is provided with the piston ring 2 that two openings 3 stagger in each compression 4 on the piston 5.
During use, earlier a piston ring 2 is put in the compression 4, and then another piston ring 2 is put into same compression 4, and opening 3 staggers.The minimum groove of piston ring 2 is an oil ring groove 1.
Claims (1)
1, piston type diesel oil, petrolic air tight piston comprise piston (5), it is characterized in that being provided with in each compression (4) on the piston (5) piston ring (2) that two openings (3) stagger.
