Abstract
The invention discloses an engine cylinder cover capable of improving the swirl rate and cooling of a valve part. The engine cylinder cover comprises a cover body. The cover body is provided with an air inlet channel, an exhaust channel, a combustion chamber, an air inlet valve pipe seat, an exhaust valve pipe seat, and water holes communicated with water jackets and grooves. A spiral groove is formed in the inner wall of the air inlet valve pipe seat. According to the engine cylinder cover, friction and abrasion of the air inlet valve pipe seat and the exhaust valve pipe seat in the working process can be avoided so that when the clearance between the rest of valve rods exceeds a design value, the engine cylinder cover can be maintained by replacing the air inlet valve pipe seat and the exhaust valve pipe seat, and the maintenance convenience is good; in addition, the water jackets and the grooves are communicated through the water holes so that cooling water in the water jackets can be directly introduced to the air inlet valve pipe seat and the exhaust valve pipe seat to be cooled, and cooling of the valve part is improved; and in addition, the inner wall of the air inlet valve pipe seat is provided with the spiral groove structure, and therefore the swirl rate of air entering the combustion chamber is larger, and the combustion efficiency and the performance of an engine can be improved.

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.
Because motor there will be high-frequency combination and is separated between valve stem and intake valve, exhaust valve in the course of the work, this makes the intake valve of cylinder and the easy fretting wear of exhaust valve part, cause valve stem can not excellent sealing inlet and outlet door, engine efficiency is caused to reduce, but cylinder head of the prior art is monolithic construction, make the maintenance after the inlet and outlet door section fretting wear of cylinder head comparatively difficult.
And when engine operation, intake valve directly contacts with high-temperature fuel gas with exhaust valve, valve portion temperature height is very fast, temperature is higher, the rising of the intensity temperature in valve portion can reduce, poor to the Cooling Design in the valve portion of cylinder head in prior art, not can solve valve portion Yin Wendu and raise the technical problem causing intensity to reduce.
And in prior art, cylinder head is only provided with an intake valve, intake duct swirl rate is little, 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 improve swirl rate and the cooling of valve portion, to solve the technical problem of cylinder head of the prior art maintenance difficult after intake valve and exhaust valve wearing and tearing; And the valve portion of cylinder head can not can be raised the technical problem causing intensity to reduce by Yin Wendu by good cooling, valve portion in solution prior art; And the intake swirl of cylinder head is less in solution prior art, air and fuel oil can not well-mixed technical problems.
The present invention can improve the engine cylinder cover of swirl rate and the cooling of valve portion, comprises lid, described lid is provided with intake duct, air outlet flue and firing chamber;
The oral area of described intake duct is provided with the intake valve base coordinated with valve stem, and described air outlet flue oral area is provided with the exhaust valve base coordinated with valve stem;
Described intake valve base and exhaust valve base include body and are arranged on the annular flange flange of body leading portion, the groove that the oral area of described intake duct and air outlet flue is provided with the recessed seam of the annular coordinated with annular flange flange and coordinates with body, the position that described body is connected with annular flange flange is provided with the groove of weakened annular flange and body thickness;
Described lid is also provided with water jacket and is communicated with the water hole of water jacket and groove;
The inwall of described intake valve base is provided with spiral chute.
Further, described body is provided with the first seal ring coordinated with groove walls, the recessed seam of described annular is provided with the second seal ring coordinated with annular flange flange.
Further, described intake valve base and exhaust valve base are straight tube structure.
Beneficial effect of the present invention:
1, the present invention can improve the engine cylinder cover of swirl rate and the cooling of valve portion, it is by arranging intake valve base and exhaust valve base at intake duct and air outlet flue oral area, make when intake valve base and exhaust valve base at work fretting wear occur, when causing the gap between all the other valve stems to exceed design load, mode by changing intake valve base and exhaust valve base is keeped in repair engine cylinder cover, and servicing ease is good.
2, the present invention can improve the engine cylinder cover of swirl rate and the cooling of valve portion, water jacket is communicated with groove by arranging water hole by it, thus the cooling water in water jacket is directly caused intake valve base and exhaust valve base cools, good cooling results, solves lid valve portion and intake valve base and exhaust valve base Yin Wendu and raises and the problem of intensity reduction.
3, the present invention can improve the engine cylinder cover of swirl rate and the cooling of valve portion, it by arranging helical groove structure on the inwall of intake valve base, 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.
