Abstract
The utility model relates to a cooling structure for a nose bridge area of a cylinder cover of a two-valve diesel engine. One straight hole (3) is arranged at the position of a water feeding opening on a bottom plate of the cylinder cover; a cooling nozzle (2) is pressed in a water jacket of the cylinder cover in an interference way through the straight hole (3); and a nozzle opening of the cooling nozzle (2) is aligned with the nose bridge area and guides cooling liquid to the nose bridge area. By using the cooling structure, as one straight hole is arranged at the position of the water feeding opening on the bottom plate of the cylinder cover, rather than one cooling pipeline is drilled on the cylinder cover, a distance between the nose bridge area and the water feeding opening is not necessary to consider; the problems that a drilling angle is too big and the drilling difficulty is high do not exist; and the strength of the bottom plate cannot be reduced.
Description
Technical field
The utility model relates to a kind of cooling structure that is used for vehicular engine cylinder cap bridge of the nose district, especially relates to a kind of two valve diesel cylinder cap bridge of the nose district cooling structures.
Background technique
Because it is modern to of the pursuit of two valve diesel to performance; Size to air flue and valve all requires bigger; Adding the oil sprayer of in-cylinder direct injection, can make the nasal bridge region that forms together between air flue and the oil sprayer not have enough spaces to make water jacket, perhaps water jacket is blocked; Can't form flow tendency smoothly, so need some special designs to realize cooling to this zone.Comparatively the common structural mode is to bore the water hole over against bridge of the nose district at present, strengthens the current in bridge of the nose district, reaches the purpose that improves bridge of the nose district cooling effect.Boring is divided into two kinds, and a kind of is rat holing from the bottom surface, and benefit is to consider sealing, and shortcoming is that cylinder diameter is greatly the time more in other words when the position in bridge of the nose district and last water hole, and the difficulty of holing is too big, can reduce the intensity of base plate simultaneously; Second method is that (air inlet or exhaust) from the side bored straight hole, and though advantage be bridge of the nose district and last water the position apart from distance can, shortcoming is to need to seal, and is easy to generate risk of leakage.
Summary of the invention
The utility model has designed a kind of two valve diesel cylinder cap bridge of the nose district cooling structures; The technical problem of its solution is that existing two valve diesel cylinder cap bridge of the nose districts cooling structures exist: the position in (1) bridge of the nose district and last water hole is cylinder diameter greatly the time more in other words; The boring difficulty is too big, can reduce the intensity of base plate simultaneously; (2) from the side (air inlet or exhaust) brill straight hole seals difficulty, is easy to generate risk of leakage.
In order to solve the technical problem of above-mentioned existence, the utility model has adopted following scheme:
A kind of two valve diesel cylinder cap bridge of the nose district cooling structures; Open a straight hole (3) in the position of cylinder head plate filling pipe end; Cooling jet (2) is pressed in the cylinder cap water jacket through said straight hole (3) interference, and the nozzle of cooling jet (2) is aimed at bridge of the nose district and with the cooling liquid bridge of the nose district of leading.
Said straight hole (3) is perpendicular to cylinder head plate.
Said cooling jet (2) comprises cooling elbow (5) and chassis (6), and said chassis (6) are pressed in the cylinder cap through said straight hole (3).
Said chassis (6) is shaped as Bowl Plug.
Position, edge, said chassis (6) has a chassis locating slot (7), and at said straight hole (a 3) next door processing cylinder head plate locating slot (4), said chassis locating slot (7) and said cylinder head plate locating slot (4) be alignment each other.
This two valve diesel cylinder cap bridge of the nose district cooling structure has following beneficial effect:
(1) the utility model is owing to open a straight hole in the position of cylinder head plate filling pipe end; Rather than on cylinder cap, bore a cooling pipe and come out, so need not consider the distance of bridge of the nose district and filling pipe end, do not exist bore angle too big; The boring difficulty is high, can not reduce the intensity of base plate.
(2) the utility model has been avoided the risk of leaking because the position that the position of cooling jet is positioned at the cylinder head plate filling pipe end is installed, thus do not worry seepy question, because all be water on every side.

Embodiment
Below in conjunction with Fig. 1 to Fig. 6, the utility model is further specified:
At first, at straight hole 3 perpendicular to base plate of the position of cylinder head plate filling pipe end processing, the aperture of this straight hole 3 is bigger, then cylinder head plate locating slot 4 of reprocessing on straight hole 3 next doors; Then cooling jet 2 is packed into by hand, the cylinder head plate locating slot 4 of the chassis locating slot 7 of cooling jet and cylinder cap aligns then, with frock chassis 6 is pressed in the cylinder cap 1, with the nearly 1mm in cylinder cap 1 bottom surface～2mm spacing again again.
The main assembly space demand of considering that arrangement space and cooling jet 2 are packed into of the size of straight hole 3 is confirmed on the cylinder cap 1, because cooling jet 2 is fitted on the cylinder cap 1 by interference, so the diameter tolerance of hole straight hole 3 needs strict control, with the assurance magnitude of interference.
Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the realization of the utility model does not receive the restriction of aforesaid way; As long as adopted method design of the utility model and the various improvement that technological scheme is carried out; Or the design of the utility model and technological scheme are directly applied to other occasion without improving, all in the protection domain of the utility model.
