Description
Technical field
The invention belongs to technical field of engines, is related to a kind of pressurized cylinder of motorcycle engine.
Background technology
Engine with supercharger is relatively conventional in automotive field, is divided into worm gear supercharging engine and mechanically-sapercharged engine, both
Principle be that air inflow is increased by impeller rotating boosting so that mixed oil and gas fully burn, with improve start it is motor-driven
Power, improve fuel economy.And motorcycle is smaller due to overall structure, it is difficult to using the pressurized construction on automobile, therefore it is logical
It is often to increase pressurized cylinder on the deflagrating jar periphery of engine, the piston movement in pressurized cylinder is driven come compressed gas by bent axle,
Supercharging is realized, such as Chinese utility model patent application (application number：200720089284.1) disclose a kind of two-cycle gasoline hair
Motivation, it is made up of working cylinder part and compressed gas cylinder portion, wherein working cylinder part includes working cylinder cylinder body, gas
Both sides are respectively arranged with intake valve and air bleeding valve at the top of cylinder, gas dome are provided with intake valve, compressed gas cylinder portion includes
By compressed gas cylinder block, it is arranged on built with piston, piston on connecting rod, cylinder top is respectively arranged with intake valve
Piece, non-return valve block, non-return valve block are connected by gas dome with intake valve, and compressed gas cylinder can provide supercharging for working cylinder
Gas, but compact-sized just because of motorcycle engine, the volume of pressurized cylinder is caused to be difficult to do larger, therefore piston list
The decrement of secondary stroke is smaller, and charging efficiency is relatively low.
The content of the invention
The purpose of the present invention is above mentioned problem be present for existing technology, it is proposed that a kind of supercharging of motorcycle engine
Cylinder, the pressurized cylinder of the motorcycle engine have higher charging efficiency.
The purpose of the present invention can be realized by following technical proposal：A kind of pressurized cylinder of motorcycle engine, including cylinder
Body and the cylinder cap for being fixed on cylinder body top, two check valve sheets for being used for cylinder body ventilation are provided with cylinder cap, it is characterised in that two
The individual check valve sheet is set in splayed, and the inner space between two check valve sheets is filled by obturator, described to fill out
Fill on body offer respectively inlet end by above-mentioned check valve sheet control break-make air admission hole and outlet side pass through above-mentioned check valve
Piece controls the steam vent of break-make.
The check valve sheet of air admission hole break-make is controlled to open when the piston in cylinder body moves down, control steam vent break-make
Check valve sheet is closed, and cylinder body controls the unidirectional of air admission hole break-make when the piston in cylinder body moves up by air inlet gas inlet hole
Valve block is closed, and the check valve sheet of control steam vent break-make is opened, and the gas in cylinder body is forced out, and supercharging is realized, wherein in cylinder body
Radial dimension it is set in the case of two check valve sheets be inclined to splayed setting, i.e., the upper edges of two check valve sheets is relative to be leaned on
Closely, lower edge is relatively distant from, and cylinder cap is made full use of in the upward space of Boring mill, so as to open up the inlet end of air admission hole
It is bigger, to increase air inflow, at the same two check valve sheets there is angle after the wedge angle that piston is difficult to reach can be formed in inner side
Shape space, the application are then filled by obturator, to reduce or eliminate the space that cylinder body inner carrier is difficult to reach, so as to
Compression ratio is improved, i.e., the application is by increasing the air inlet end area of air admission hole, to improve air inflow, with reference to obturator, to reduce
Gas residual quantity when piston compresses in cylinder body, so as to improve the charging efficiency of pressurized cylinder.
In the pressurized cylinder of above-mentioned motorcycle engine, the inlet end area of section of the air admission hole is more than air admission hole
The inlet end area of section sum of outlet side area of section and steam vent.I.e. the inlet end of air admission hole is more than outlet side, in air-flow
Enter fashionable generation Venturi effect, i.e., flow velocity becomes big when air-flow passes through air admission hole the inner, so as to increase air inflow, and relative to straight
Connect the whole air admission hole of increase to compare to increase the conventional art means of air inflow, this air admission hole can reduce air inlet after piston compression
Gas residual quantity in hole, that is, be correspondingly improved compression ratio.
In the pressurized cylinder of above-mentioned motorcycle engine, the obturator and cylinder cap are integral type structure, and obturator

It can take advantage of a situation into air admission hole, avoid elastic spring from giving birth to resistance to gas stream movable property, similarly, gas flows from the bottom to top in exhaust
Dynamic, the elastic spring upper end of steam vent outlet side can outwards take advantage of a situation swings so that gas, which can take advantage of a situation, flows out steam vent, avoids
Elastic spring gives birth to resistance to gas stream movable property.
In the pressurized cylinder of above-mentioned motorcycle engine, the inlet end aperture edge of the air admission hole and going out for steam vent
Gas stomidium mouth edge circumferentially has recessed shoulder, and the edge of two limiting plates is born against in two recessed shoulders, wherein with air inlet
Throttle valve body is fixed with the mounting surface in hole, the port edges of the throttle valve body are pressed on outside the limiting plate at air admission hole inlet end
Side edge, have and be fixed with voltage stabilizing casing on the mounting surface of steam vent, the port edges of the voltage stabilizing casing are pressed on steam vent
Limiting plate lateral surface edge at outlet side.Gas is entered in cylinder body by throttle valve body, in press-in pressurizer tank body, wherein air inlet
The limiting plate at gas inlet hole end is directly pressed in recessed shoulder by throttle valve body, and the limiting plate of steam vent outlet side directly passes through voltage stabilizing
Casing is pressed in recessed shoulder, so as to reduce connection member, simplifies structure.
Compared with prior art, the pressurized cylinder of this motorcycle engine has advantages below：
1st, because the radial dimension in cylinder body is set in the case of two check valve sheets be obliquely installed, make full use of cylinder cap in cylinder
Space on body axial direction, it is bigger so as to open up the inlet end of air admission hole, to realize that the inlet end of air admission hole is more than
Gas end, flow velocity becomes big when air-flow passes through air admission hole the inner, so as to increase air inflow.
2nd, because air admission hole the inner is smaller, the gas residual quantity in air admission hole after piston compresses can be reduced, two unidirectional
Space on the inside of valve block is filled by obturator, to reduce or eliminate the space that cylinder body inner carrier is difficult to reach, so as to
Improve compression ratio and charging efficiency.
3rd, arch upward because the air admission hole inlet end hole wall relative with check valve sheet is curved and close to check valve sheet, can subtract
Gas residual quantity after few piston compression in air admission hole, so as to improve compression ratio, while the hole wall arc at this arch upward and with list
