Abstract
The invention discloses a cylinder cover of an engine. The cylinder cover is internally provided with an air inlet channel and an air outlet channel; a first spherical groove is formed at an air inlet throat opening of the air inlet channel; and a second spherical groove is formed at an air outlet throat opening of the air outlet channel. With the adoption of the arrangement, the cylinder cover of the engine can reduce the resistance borne by an air flow in the air inlet channel effectively, increases air input of the engine, and allows oil and air to be mixed more sufficiently when the engine works. The invention further provides the engine comprising the cylinder cover.
Description
Technical field
The present invention relates to technical field of engines, relate to more specifically a kind of motor and cylinder cap thereof.
Background technique
Motor is as the heart of automobile, and sufficient air inflow can guarantee that air-fuel mixture is abundant, and then improves engine power performance and reduce discharging.
The intake duct of motor and air outlet flue are arranged on the cylinder cap of motor, in prior art, intake duct is the common blank hole of casting, behind the aditus laryngis place of air-flow through intake duct, pass through again in the valve flowing in combustion chamber, yet, be the common blank hole of casting due to intake duct of the prior art, the resistance that air-flow runs into through its throat location the time is larger, and then has affected the air inflow of motor.
Therefore, how to reduce the resistance that in prior art, air-flow is subject in the intake duct of cylinder cap, become those skilled in the art's important technological problems to be solved.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of cylinder cap of motor, it can effectively reduce the resistance that air-flow is subject in intake duct, increased the air inflow of motor, and when making engine operation, air-fuel mixture is more abundant.The present invention also provides a kind of motor that comprises above-mentioned cylinder cap.
The cylinder cap of a kind of motor provided by the invention is provided with intake duct and air outlet flue in described cylinder cap, the air inlet aditus laryngis place of described intake duct is provided with the first ball recess, and the exhaust aditus laryngis place of described air outlet channel is provided with the second ball recess.
Preferably, the radius of described the first ball recess is 5-7mm, and the radius of described the second ball recess is 8.5-10.5mm.
Preferably, the radius of described the first ball recess is 6mm, and the radius of described the second ball recess is 9.5mm.
The present invention also provides a kind of motor, comprises the as above described cylinder cap of any one.
The cylinder cap of a kind of motor provided by the invention is provided with intake duct and air outlet flue in described cylinder cap, the air inlet aditus laryngis place of described intake duct is provided with the first ball recess, and the exhaust aditus laryngis place of described air outlet channel is provided with the second ball recess.so arrange, cylinder cap provided by the invention, because the air inlet aditus laryngis place of its intake duct is provided with the first ball recess, when extruding from the gap between valve and cylinder wall after the gas shock valve, can roll stream in first ball recess place's formation, simultaneously, the exhaust aditus laryngis place of air outlet flue is provided with the second ball recess, same air-flow is during through the second ball recess place of the exhaust aditus laryngis of air outlet flue, also can form and roll stream increase Ventialtion rate, so in the balance that does not affect charge flow rate and extraction flow, increased Ventialtion rate, and then improved engine intake airflow.
The present invention also provides a kind of motor, comprises cylinder cap as above.So arrange, motor provided by the invention, it can effectively increase its air inflow, makes air-fuel mixture more abundant.The beneficial effect derivation that the derivation of this beneficial effect and above-mentioned cylinder cap bring is substantially similar, therefore this paper repeats no more.

Embodiment
The invention provides a kind of cylinder cap of motor, it can effectively reduce the resistance that air-flow is subject in intake duct, has increased the air inflow of motor, and when making engine operation, air-fuel mixture is more abundant.The present invention also provides a kind of motor that comprises above-mentioned cylinder cap.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technological scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment who obtains under the creative work prerequisite.
Please refer to Fig. 1, Fig. 1 intake duct provided by the invention and air outlet flue schematic diagram.
The cylinder cap of motor provided in the present embodiment is provided with intake duct 11 and air outlet flue 12 in cylinder cap, the air inlet aditus laryngis place of intake duct 11 is provided with the first ball recess 13, and the exhaust aditus laryngis place of air outlet flue 12 is provided with the second ball recess 14.
So arrange, cylinder cap provided in the present embodiment, because the air inlet aditus laryngis place of its intake duct 11 is provided with the first ball recess 13, the exhaust aditus laryngis place of air outlet flue 12 is provided with the second ball recess 14.When extruding from the gap between valve and cylinder wall after the gas shock valve, can roll stream in the first ball recess 13 places formation, increased Ventialtion rate, simultaneously, the exhaust aditus laryngis place of air outlet flue 12 is provided with the second ball recess 14, same air-flow is during through second ball recess 14 place at the exhaust aditus laryngis place of air outlet flue 12, also can form and roll stream increase Ventialtion rate, so in the balance that does not affect charge flow rate and extraction flow, increase Ventialtion rate, and then improved engine intake airflow.
In the preferred version of this embodiment, the radius of the first ball recess 13 is 5-7mm, and the radius of the second ball recess is 8.5-10.5mm.
Please refer to following table 1, table 1 is Flow coefficient of inlet correlation data table in intake duct provided by the invention and prior art.
Table 1
Can find out intuitively from table 1, when valve lift is consistent with the ratio of the diameter of air valve seat ring, if the radius of the first ball recess 13 is made as 5-7mm, the radius of the second ball recess is made as 8.5-10.5mm, the flow coefficient of intake duct provided by the invention and air outlet channel is apparently higher than the flow coefficient of intake duct of the prior art and air outlet channel, and then effectively improved the air inflow of motor, can make the more abundant of air-fuel mixture.
Further, the radius of the first ball recess 13 provided in the present embodiment is 6mm, and the radius of the second ball recess 14 is 9.5mm.The radius of the first ball recess 13 is made as 6mm, and when the radius of the second ball recess 14 was made as 9.5mm, the flow coefficient of intake duct provided by the invention and air outlet channel was maximum, and then so arranged, and the air inflow of motor is also maximum.
This embodiment also provides a kind of motor, comprises cylinder cap as above.So arrange, motor provided in the present embodiment, it can effectively increase its air inflow, makes air-fuel mixture more abundant.The beneficial effect derivation that the derivation of this beneficial effect and above-mentioned cylinder cap bring is substantially similar, therefore this paper repeats no more.
Above a kind of motor provided by the present invention and cylinder cap thereof are described in detail, used specific case herein principle of the present invention and mode of execution are set forth, above embodiment's explanation just is used for helping to understand method of the present invention and core concept thereof.Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also carry out some improvement and modification to the present invention, these improvement and modification also fall in the protection domain of claim of the present invention.
