Abstract
The utility model discloses a gas ring cooling structure of diesel engine, which is characterized in that an annular cooling trough is arranged on opposite position at the upper dead point of gas ring on cylinder and cylinder sleeve, the side of cooling trough is provided with an inlet connecting with cooling water channel of the diesel engine and the other side has outlet connecting the cooling water channel of the cylinder cover. The utility model is arranged on combination position of the cylinder and the cylinder sleeve head, the cooling liquid flows round the cylinder sleeve by cooling trough for taking away the heat quantity, the heat radiation condition of the gas ring on upper dead point can be effectively improved and the failure because of gas ring caused by too high temperature can be avoided.
Description
Technical field
The utility model relates to a kind of piston ring cooling structure that is used for cylinder of diesel engine.
Background technique
The function of diesel engine top piston ring (compression ring) is the sealing that guarantees between piston and cylinder wall, prevents that the pressurized gas of piston top from entering crankcase.Except sealing, piston ring also plays the effect of heat transfer, the heat that piston head absorbed, and major part will be passed to cylinder wall by compression ring, is taken away by the cooling medium of outside again.
When piston was in top dead center, generally speaking, compression ring was answered all or part of being positioned at below the cooling water channel upper-end surface, so that can in time dispel the heat.For highly-intensified diesel engine, because of the restriction of structure and reinforcing degree, often can not meet above-mentioned requirements, the heating that compression ring is subjected to piston and combustion gas more very, when temperature was too high, compression ring tended to may cause scuffing of cylinder bore and gas leakage because of gum deposit follows the string and mobility.
The model utility content
The purpose of this utility model is to provide a kind of diesel engine compression ring cooling structure, and it can improve the heat dissipating state of compression ring when top dead center, avoids compression ring Yin Wendu too high and lost efficacy.
The technical solution of the utility model is: the diesel engine compression ring is contained in piston tip, the compression ring outside contacts with the cylinder sleeve that is arranged in cylinder, improvements are to be in the corresponding position of top dead center position with compression ring to be provided with the ring-type cooling bath on cylinder and cylinder sleeve, one side of cooling bath has import, and opposite side has outlet.
Described cooling bath import communicates with the diesel coolant road, and outlet communicates with the cylinder head cooling water channel; The transverse section of cooling bath is circular-arc.
The utility model is provided with the ring-type cooling bath on cylinder and cylinder sleeve, the cooling bath position is corresponding at top dead center position with compression ring, generally be in equal height, cooling liquid from cylinder cooling water channel enters cooling bath by import, after one week, enters cylinder head cooling water channel from outlet around cylinder sleeve, coolant flow is unobstructed, take away heat, thereby effectively improve the heat dissipating state of compression ring when top dead center, avoid compression ring Yin Wendu too high and lost efficacy.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
As figure, cylinder 2 and cylinder sleeve 1 are provided with ring-type cooling bath 4, position when the cooling bath position is in top dead center with the compression ring 5 that is contained in piston 6 tops is contour, the cooling bath transverse section is circular-arc, cooling bath one side has the import 3 that communicates with the diesel coolant road, and opposite side has the outlet 7 that communicates with the cylinder head cooling water channel.
Claims (3)
1, a kind of diesel engine compression ring cooling structure, compression ring is contained in piston tip, and the compression ring outside contacts with the cylinder sleeve that is arranged in cylinder, it is characterized in that being in the corresponding position of top dead center position with compression ring on cylinder and cylinder sleeve is provided with the ring-type cooling bath, one side of cooling bath has import, and opposite side has outlet.
2, by the described diesel engine compression ring of claim 1 cooling structure, it is characterized in that the cooling bath import communicates with the diesel coolant road, outlet communicates with the cylinder head cooling water channel.
