Abstract
The utility model discloses an environmental protective oil-saving piston comprising a piston body (1) and a third ring land (4). The utility model is characterized in that at least one radial oil drainage hole (5) which penetrates the piston body (1) is arranged on the third ring land (4). The motor oil scraped from an oil ring doesn not enter a burning chamber to burn.The utility model is the environmental protective oil-saving piston with simple structure, convenient manufacture and dependable performance.
Description
Technical field
The utility model relates to a kind of piston, particularly relates to a kind of environmental protection fuel-saving type piston.
Background technique
General compression ring and the oil ring of adopting finished sealing and the effect of control oil on piston body, the 3rd ring at piston body is provided with compression ring in the side on the bank, its below is provided with oil ring, the main effect of compression ring is a sealing gas, and auxiliary knife-type oil stripping action arranged, and the effect of oil ring is cloth oil and wipes unnecessary machine oil off, in order to avoid machine oil enters combustion chambers burn.When piston in cylinder during high-speed motion, partly machine oil is deposited between the oil ring and compression ring of the 3rd ring bank, increase along with the machine oil accumulation, machine oil will raise at the oil ring and the pressure between the compression ring of the 3rd ring bank, and finally cross compression ring and scurry into combustion chambers burn, emit blue smoke, befouling environment, and because the burning carbon deposit that machine oil caused increases the weight of the wearing and tearing of piston assembly and the working efficiency of reduction internal-combustion engine again.In the running-in period of piston ring with piston ring, piston, cylinder wear make the frizing and oil-sealing performance reduction of piston ring when increasing after, scurry scaling loss on the machine oil, the carbon deposit that is produced has more increased the weight of the wearing and tearing to piston assembly.
The model utility content
Technical problem to be solved in the utility model provides a kind of machine oil of scurrying into the oil ring top can not enter the environmental protection fuel-saving type piston of combustion chambers burn.
The technological scheme that the utility model adopts in order to solve the problems of the technologies described above is: a kind of environmental protection fuel-saving type piston, comprise piston body and the 3rd ring bank thereof, it is characterized in that: be provided with a radially draining hole that connects described piston body on the bank at least at described the 3rd ring.
As a kind of improvement of the present utility model, the aperture in described radially draining hole is 0.10～5.0mm.
Adopt the environmental protection fuel-saving type piston of technique scheme, owing to be provided with the radially draining hole that connects piston body on the bank at the 3rd ring, when piston in cylinder during high-speed motion, the high-pressure oil of scurrying into oil ring top is gone into piston cavity by draining orifice flow radially and is got back in the crankcase, its oil pressure is reduced, prevent to scurry scaling loss on the machine oil, reduced oil consumption.
In sum, the utility model is that a kind of machine oil of scurrying into the oil ring top can not enter combustion chambers burn and environmental protection fuel-saving type piston simple in structure, easily manufactured, reliable performance.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
Referring to accompanying drawing, be the radially draining hole 5 of 2mm by comprising that piston body 1, wrist pin 2, snap ring 3, first compression ring 6, second compression ring 7, oil ring 8 are drilled with the aperture that connects piston body 1 on the 3rd ring bank 4 of piston body 1.
Owing on the 3rd ring bank 4, be provided with radially draining hole 5, when piston body 1 in cylinder during high-speed motion, the high-pressure oil of oil ring 8 tops flows into piston bodies 1 inner chamber by draining hole 5 radially and gets back in the crankcase, and its oil pressure is reduced, prevent to scurry scaling loss on the machine oil, reduced oil consumption.
Claims (2)
1, a kind of environmental protection fuel-saving type piston comprises piston body (1) and the 3rd ring bank (4) thereof, it is characterized in that: be provided with a radially draining hole (5) that connects described piston body (1) at least on described the 3rd ring bank (4).
2, a kind of environmental protection fuel-saving type piston according to claim 1, it is characterized in that: the aperture in described radially draining hole (5) is 0.10～5.0mm.
