Specific embodiment
With reference to the accompanying drawing, specific embodiments of the present invention will be described in detail, it is to be understood that guarantor of the invention
Shield range is not limited by the specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " includes " or its change
Changing such as "comprising" or " including " etc. will be understood to comprise stated element or component, and not exclude other members
Part or other component parts.
As shown in Figure 1 to Figure 3, the water inlet structure of a kind of cylinder jacket water jacket 10 of specific embodiment according to the present invention, packet
Lateral inlet channel 1 and longitudinal inlet channel 2 are included, L-shaped, the cross wherein lateral inlet channel 1 extends outwardly from cylinder sleeve bleeder 11
It connect to form arcwall face 12 in the outside of cylinder sleeve bleeder 11 with the lateral wall of cylinder jacket water jacket 10 to the lateral wall of inlet channel 1,
The lateral wall of lateral inlet channel 1 connect to form rounded face with the lateral wall of cylinder jacket water jacket 10 in the inside of cylinder sleeve bleeder 11
13, longitudinal inlet channel 2 was connected to the end of lateral inlet channel 1 and in sagging type (referring to fig. 2), and the end of longitudinal inlet channel 2 is
Balance port 23 of intaking (participating in Fig. 3), the sectional area for balance port 23 of intaking are determined according to thin-walled aperture flow rate calculation formula.
In above scheme, since the flow rate of water flow for flowing to cylinder sleeve two sides at conventional engines cylinder sleeve bleeder is uneven,
In the present solution, the lateral wall of lateral inlet channel 1 connect shape in the outside of cylinder sleeve bleeder 11 with the lateral wall of cylinder jacket water jacket 10
The lateral wall in camber face 12, lateral inlet channel 1 is connect with the lateral wall of cylinder jacket water jacket 10 in the inside of cylinder sleeve bleeder 11
Rounded face 13 is formed, arcwall face 12 can be such that cooling water enters along cylinder sleeve tangential direction, play the guiding role to the flowing of water, and
It effectively prevent water inlet cavitation pitting.Rounded face 13 can be such that cooling water enters along circular hole water jacket tangential direction, be conducive to water
Flowing, and prevent water inlet cavitation pitting.Meanwhile the bifurcation structure of cylinder sleeve bleeder is designed in this way, can play keeps coolant liquid uniform
Distributional effects.
In addition, due to having on-way resistance during water flowing, it is inconsistent to will lead to each water inlet balance port hydraulic pressure, to lead
It causes the water flow for entering each cylinder to differ greatly, it is uneven to eventually lead to cylinder sleeve heat dissipation.In the present solution, by longitudinal inlet channel 2
Tip designs are at water inlet balance port 23 (participating in Fig. 3), and the sectional area for balance port 23 of intaking is according to thin-walled aperture flow rate calculation formula
Determine, can according to each point water feeding pressure size adjust water inlet captured area size, thus reach make cooling water even into
Each cylinder sleeve is cooled down.
Specifically, according to thin-walled aperture flow rate calculation formula:Wherein qv-flow (m3/s) in formula；
Cd-discharge coefficient；A-orifice area；Pressure difference (Pa) before and after Δ p-aperture；ρ-fluid density (kg/m3).This formula it is found that
Water inlet balance port sectional area is determined according to water inlet balance port pressure difference, it is ensured that each cylinder uniform flow.Certainly, such as body water inlet
Position is inconsistent, also results in the pressure gap of each water inlet balance port, in short, the difference of the pressure difference of water inlet balance port can be led
Cause the sectional area of each water inlet balance port inconsistent.
As a kind of preferred embodiment, the bottom position (referring to fig. 2) of cylinder jacket water jacket 10 is arranged in cylinder sleeve bleeder 11.
In the present solution, since conventional engines water jacket majority is arranged in body cylinder holes waist and with upper bit, first to upper portions under heat
Area is preferentially cooled down, and the convection current or turbulent flow for recycling the temperature difference to generate cool down lower part.It will lead under body in this way
Half part water flowing is very poor, it is understood that there may be slough.In the present solution, the bottom end of cylinder jacket water jacket 10 is arranged in cylinder sleeve bleeder 11
Position, so that partial distance very little under the lower part of the water inlet structure and cylinder sleeve, or part slightly less than under cylinder sleeve.So can both it make
Part is preferential cooling on cylinder sleeve, and also can solve part under cylinder sleeve, there may be slough problems.
As a kind of preferred embodiment, longitudinal inlet channel 2 and the upper wall 21 of the junction of lateral inlet channel 1 are tilted in upward
Shape.In the present solution, upper wall 21 has upward gradient, there is guiding role to water flow, water flows into top from below, this turning can make
The water flowing of top is greater than lower section, is so conducive to the cooling on cylinder sleeve top.In the present solution, longitudinal inlet channel 2 with laterally into
The lower wall 22 of the junction of water channel 1 is designed to small round corner or small oblique angle, and flow velocity is slightly smaller, can drive the stream of part cooling water under cylinder sleeve
It is dynamic, prevent slough.
As a kind of preferred embodiment, cylinder jacket water jacket 10 is six cylinder water jackets, and every cylinder water jacket all has water inlet structure.At this
In scheme, since the pressure difference of the water inlet balance port of six cylinder water jackets is sequentially reduced, to guarantee each cylinder uniform flow, therefore balance port of intaking
Sectional area be sequentially increased.
To sum up, the water inlet structure of the cylinder jacket water jacket 10 of the present embodiment, first does the flow dividing structure at cylinder sleeve bleeder
Peculiar design out, it is ensured that the flow rate of water flow for flowing to cylinder sleeve two sides is uniform, can make the more uniform distribution of coolant liquid, and will not draw
Play cavitation pitting.Meanwhile the sectional area for balance port 23 of intaking adjusts the captured area size of water inlet according to water feeding pressure size, thus
Reaching cools down cooling water even into each cylinder sleeve, so that the water flow into each cylinder is almost the same, guarantees cylinder sleeve heat dissipation
Uniformly.
The aforementioned description to specific exemplary embodiment of the invention is in order to illustrate and illustration purpose.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to the above instruction, can much be changed
And variation.The purpose of selecting and describing the exemplary embodiment is that explaining specific principle of the invention and its actually answering
With so that those skilled in the art can be realized and utilize a variety of different exemplary implementation schemes of the invention and
Various chooses and changes.The scope of the present invention is intended to be limited by claims and its equivalents.
