Abstract
The invention discloses an engine cylinder cover capable of enhancing the air and fuel oil mixing effect. The engine cylinder cover comprises a cover body. The cover body is provided with an air inlet channel and an exhaust channel, and a spiral groove is formed in the pipe wall of an outlet part of the air inlet channel. According to the engine cylinder cover capable of enhancing the air and fuel oil mixing effect, the spiral groove structure is arranged on the pipe wall of the outlet part of the air inlet channel, and rotation movement is applied to air before the air enters a combustion chamber, so that the eddy ratio of the air entering the combustion chamber is larger, the air and fuel oil are 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 strengthen air and fuel oil mixed effect, less with the intake swirl solving cylinder head of the prior art, air and fuel oil can not well-mixed technical problems.
The present invention can strengthen the engine cylinder cover of air and fuel oil mixed effect, comprises lid, described lid is provided with intake duct and air outlet flue, and export department's tube wall of described intake duct is provided with spiral chute.
Further, the export department of described intake duct is straight tube structure.
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:
The present invention can strengthen the engine cylinder cover of air and fuel oil mixed effect, 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 strengthen the engine cylinder cover of air and fuel oil mixed effect.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in the figure, the present embodiment can strengthen the engine cylinder cover of air and fuel oil mixed effect, comprises lid 1, described lid is provided with intake duct 2 and air outlet flue 3, and export department's tube wall of described intake duct is provided with spiral chute 4.
The present embodiment can strengthen the engine cylinder cover of air and fuel oil mixed effect, 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 1 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 provided with cooling water passage 5 on the oral area side of intake duct and air outlet flue, utilize the cooling water flowing through lonely water channel to cool hood 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.
What finally illustrate is, above embodiment is only in order to illustrate technological scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technological scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
Claims (3)
1. can strengthen an engine cylinder cover for air and fuel oil mixed effect, it is characterized in that: comprise lid, described lid be provided with intake duct and air outlet flue, export department's tube wall of described intake duct is provided with spiral chute.
