Abstract
The invention discloses an engine cylinder cover capable of increasing the swirl ratio. The engine cylinder cover capable of increasing the swirl ratio comprises a cover body which is provided with an air inlet channel, an air exhaust channel and a combustion chamber; a spiral groove is formed in the pipe wall of the outlet part of the air inlet channel; the portion, surrounding the combustion chamber, of the cover body is provided with an annular sealing ring installing groove; and a sealing ring is arranged in the sealing ring installing groove. According to the engine cylinder cover capable of increasing the swirl ratio, the sealing ring is arranged on the portion, surrounding the combustion chamber, of the cylinder cover to seal fuel gas, and the sealing structure is easy to manufacture; and according to the sealing ring, an elastic steel protecting piece is supported by a rubber gasket, so that the rebound resilience of the sealing ring is good, and the sealing effect is good. Besides, due to the fact that the spiral groove structure is arranged on the pipe wall of the outlet part of the air inlet channel, and air does rotation motion in advance before entering the combustion chamber, the swirl ratio of the air entering the combustion chamber can be larger, air and fuel oil can be mixed more evenly, and the combustion efficiency and the engine performance can be improved.
Description
Technical field
The present invention relates to a kind of engine components, particularly a kind of cylinder cap of motor.
Background technique
Cylinder head is one of main parts size of motor, and major function is sealing cylinder top, and forms firing chamber with piston head together with cylinder.Cylinder head is provided with intake valve and exhaust valve, be provided with valve stem in intake valve and exhaust valve, motor in the course of the work, controls the opening and closing of intake valve and exhaust valve by valve stem, realize from intake valve inhale fresh air or combustion gas, discharge the waste gas after burning from exhaust valve.
In prior art, cylinder cap is only provided with an intake valve, intake duct swirl rate is little, and this causes the air entered in cylinder to be difficult to fully mix with fuel oil, is unfavorable for fuel oil Thorough combustion, affects the performance of motor.Therefore, how carrying induction swirl ratio in firing chamber, guarantee that air fully can mix with fuel oil, is the technical problem that those skilled in the art are devoted to solve always.
Summary of the invention
In view of this, the object of this invention is to provide a kind of engine cylinder cover that can increase swirl rate, less to solve the intake swirl of cylinder head in prior art, air and fuel oil can not well-mixed technical problems; And solve the technical problem of cylinder head of the prior art maintenance difficult after intake valve and exhaust valve wearing and tearing.
The present invention can increase the engine cylinder cover of swirl rate, comprises lid, described lid is provided with intake duct, air outlet flue and firing chamber;
Export department's tube wall of described intake duct is provided with spiral chute;
Described lid is provided with O-ring seal mounting groove around firing chamber, be provided with seal ring in described seal ring mounting groove, described seal ring comprises annular reinforcing bar sheet, be arranged on rubber pad on annular reinforcing bar sheet bi-side and the Elastic Steel bluff piece of sealed envelope outside rubber pad.
Further, the export department of described intake duct is straight tube structure.
Further, described lid is also provided with the recessed seam coordinated with cylinder liner, described recessed seam is provided with steel plate washer.
Further, the surface of described steel plate washer is provided with annular projection.
Further, described lid is provided with cooling water passage on the oral area side of intake duct and air outlet flue.
Beneficial effect of the present invention:
1, the present invention can increase the engine cylinder cover of swirl rate, it adopts and around cylinder head upper combustion chamber, arranges seal ring seal combustion gas, the making of sealing configuration is simple, and the seal ring in the present invention utilizes rubber pad to support Elastic Steel bluff piece, make the resilience of seal ring good, sealing effect is good; The intensity of its Elastic Steel bluff piece and annular reinforcing bar sheet is good simultaneously, and make the structural strength of seal ring good, not fragile, and rubber pad is by Elastic Steel bluff piece sealed envelope, and it is not contacted with high-temperature fuel gas, the life-span of seal ring is long; Thus solve existing head combustion chamber sealing there is the technical problem that difficulty of processing is large, sealing effect is poor.
2, the present invention can increase the engine cylinder cover of swirl rate, it by arranging helical groove structure on export department's tube wall of intake duct, air is added with rotary motion in advance before entering firing chamber, thus make the swirl rate of the air entering firing chamber larger, air and fuel oil mix evenly, combustion efficiency and engine performance can be improved.
Accompanying drawing explanation
Fig. 1 is the broken section structural representation that the present embodiment can increase the engine cylinder cover of swirl rate;
Fig. 2 is the enlarged diagram in P portion in Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in the figure, the present embodiment can increase the engine cylinder cover of swirl rate, comprises lid 1, described lid is provided with intake duct 2, air outlet flue 3 and firing chamber 4;
Export department's tube wall of described intake duct is provided with spiral chute 5;
Described lid is provided with O-ring seal mounting groove around firing chamber, be provided with seal ring 6 in described seal ring mounting groove, described seal ring comprises annular reinforcing bar sheet 61, be arranged on rubber pad 62 on annular reinforcing bar sheet bi-side and the Elastic Steel bluff piece 63 of sealed envelope outside rubber pad.
The present embodiment can increase the engine cylinder cover of swirl rate, it adopts and around cylinder head upper combustion chamber, arranges seal ring seal combustion gas, the making of sealing configuration is simple, and the seal ring in the present invention utilizes rubber pad to support Elastic Steel bluff piece, make the resilience of seal ring good, sealing effect is good; The intensity of its Elastic Steel bluff piece and annular reinforcing bar sheet is good simultaneously, and make the structural strength of seal ring good, not fragile, and rubber pad is by Elastic Steel bluff piece sealed envelope, and it is not contacted with high-temperature fuel gas, the life-span of seal ring is long; Thus solve existing head combustion chamber sealing there is the technical problem that difficulty of processing is large, sealing effect is poor.
And the present embodiment can increase the engine cylinder cover of swirl rate, it by arranging helical groove structure on export department's tube wall of intake duct, air is added with rotary motion in advance before entering firing chamber, thus make the swirl rate of the air entering firing chamber larger, air and fuel oil mix evenly, combustion efficiency and engine performance can be improved.
As the improvement to the present embodiment, the export department of described intake duct 2 is straight tube structure, and the resistance of straight tube structure is less, is conducive to improving air velocity, and then improves the mixed effect of air and fuel oil.
As the improvement to the present embodiment, described lid is also provided with the recessed seam coordinated with cylinder liner, described recessed seam is provided with steel plate washer 7, can be sealed combustion gas further by steel plate washer, can ensure to start function normally to work when seal ring damages.
As the improvement to the present embodiment, the surface of described steel plate washer is provided with annular projection 8, by the resiliently deformable of annular projection, the sealing effect of steel plate washer can be improved further.
As the improvement to the present embodiment, described lid is provided with cooling water passage 9 on the oral area side of intake duct and air outlet flue, utilize the cooling water flowing through lonely water channel to cool lid and seal ring during engine operation, the intake duct that hood local superheating can be avoided to cause and air outlet channel oral area cross the problem such as quick-wearing, deformed damaged.
