Description
Technical field
The present invention relates to field of internal combustion engine, more particularly to a kind of gas machine air intake duct.
Background technology
Talk about publicly it is known, gas machine air intake duct be Combustion System Design and cylinder cap general structure design important component it
One, good volumetric efficiency and air movement state play the role of in-cylinder combustion key.Rational air intake duct pattern simultaneously
It is also beneficial to cylinder cap overall structural arrangement and design, ensures gas machine overall performance and discharge, improves Cooling of Cylinder Head, is improved reliable
Property.Existing Four valve gas machine valve generally use arranged in series or torsion arrangement, air intake duct are usually the air flue or partly simultaneously of connecting
The air flue of connection, one of them is helical intake, another is tangential air flue or is double helix air intake duct；Using above-mentioned air flue cloth
The air intake duct for setting form is conjuncted air flue, has conjuncted air intake duct identical with number of cylinders in each cylinder head, to meet
Air flue and cooling jacket arrangement space, while under the premise of taking into account casting manufacturability, the cylinder head using existing air intake duct is usual
Installation and the sealing Water Cavity of Cylinder Head of spark plug are realized using edge spark plug boot.Meanwhile to improve compatibility, air intake duct can collect
At air feeder structure, sealed interface is reduced, ensures air inlet consistency, improves use reliability.
Gas machine intake port layout is related to vortex intensity and discharge coefficient in cylinder, while it is logical to influence the cooling of cylinder cap ridge area
Road arranges that there are the following problems for existing gas machine intake port layout：
1, series connection or mid-shunt air intake duct two air inlet runners in engine intake process, which exist, interferes with each other situation,
In the case of different valve strokes, proximal end valve air-flow is more disorderly, influences each cylinder swirl ratio uniformity；
2, be to meet air flue and cooling jacket arrangement space, while under the premise of taking into account casting manufacturability, using it is existing into
The cylinder head generally use of air flue inlays spark plug boot to realize installation and the sealing Water Cavity of Cylinder Head of spark plug, but installs spark
Filling in sheath needs dedicated tooling device to ensure that technique is cumbersome, while increasing cylinder head cost；
3, as gas machine discharges upgrading and power ascension, explosion pressure is constantly promoted in cylinder, inlays the gas of spark plug boot
Cylinder cap fire power face structural strength is relatively low, and there are cylinder-head distortions, and big, cylinder head gasket seal failure, spark plug boot leak etc. are latent
In risk；

7.Air inlet pipe 1 is receiving through the filtered clean air of air cleaner；The first series connection series connection of twin-inlet 2 to the 6th it is double into
One end of air flue 7 is connected to air inlet pipe 1 respectively, and the other end is connected to the first cylinder to the 6th cylinder respectively, and the first series connection is double
Air intake duct 2 to the 6th connect twin-inlet 7 the other end be respectively provided with the first proximal end air intake duct 21, the second proximal end air intake duct 31,
Third proximal end air intake duct 41, the 4th proximal end air intake duct 51, the 5th proximal end air intake duct 61 and the 6th proximal end air intake duct 71 and first are remote
Hold 22 to the 6th distal end air intake duct 72 of air intake duct；Wherein, 22 to the 4th distal end air intake duct 52 of the first distal end air intake duct be spiral into
Air flue；Wherein, the 5th distal end air intake duct 62 is tangential air flue；Wherein, 71 part of the 6th proximal end air intake duct is narrowed, and the 6th proximal end
It is narrowed the inlet of air intake duct 71.
Preferably, gas machine air intake duct further includes：First row air flue to the 6th exhaust duct, respectively with the first cylinder to
Six cylinders be connected to, and first row air flue to the 6th exhaust duct with first connect twin-inlet 2 to the 6th series connection twin-inlet 7 surround
Spark plug adapter surrounding is arranged in parallel.
Preferably, air inlet pipe 1 is integrated in cylinder head；First series connection twin-inlet 2 to the 6th connect twin-inlet 7 with into
The inner cavity 11 of tracheae 1 is an integral structure；First series connection twin-inlet 2 to the 6th twin-inlet 7 of connecting all has and allows bit platform,
Bit platform is allowed to be installed to valve guide bushing.
In practical applications, air intake duct, exhaust duct are around spark plug adapter surrounding parallel arrangement (the i.e. first series connection twin-inlet
2 to the 6th series connection twin-inlets 7 are arranged in parallel with first row air flue to the 6th exhaust duct around spark plug adapter surrounding), Mei Geqi
Cylinder all has an air intake duct, divides distal end air intake duct and proximal end air intake duct, each same main air intake of cylinder that two valves is divided to enter
Cylinder, distal end air intake duct and proximal end air intake duct all there are one bit platform is allowed, are installed for valve guide bushing, the entrance of air intake duct with into
It combines together the inner cavity 11 of tracheae 1.
When gas machine works, by the clean air that air cleaner filters, by entering air inlet pipe 1 after compressed
Inner cavity 11 in, it is double then to pass through the concatenated first series connection series connection of twin-inlet 2 to the 4th of the first cylinder to the 4th cylinder single cylinder
6th series connection twin-inlet 7 of the concatenated 5th series connection twin-inlet 6 of air intake duct 5, the 5th cylinder single cylinder and the 6th cylinder single cylinder
Into in the combustion chamber of each cylinder.Wherein according to the installation site of air inlet tube, by the first cylinder to the first of the 4th cylinder
The first distal end air intake duct 22, the second distal end air intake duct 32 in the series connection series connection twin-inlet 5 of twin-inlet 2 to the 4th, third are remote
It holds air intake duct 42 and the 4th distal end air intake duct 52 to increase helical structure (spiral inlet duct), air can be effectively improved around cylinder axis
Rotary speed, the 5th distal end air intake duct 62 of the 5th of the 5th cylinder series connection twin-inlet 6 is set as tangential air flue, Ke Yigai
Kind cylinder interior air-flow rotation nearby narrows part the 6th proximal end air intake duct 71 of the 6th series connection double air passage of the 6th cylinder, together
When entrance structure is narrowed, be vortexed to form speed to reduce the cylinder, so while can guarantee each cylinder air inflow, ensure
Cylinder uniformity ensures burning fully, steadily.
In short, the gas machine air intake duct of the present invention has the advantages that：
1, according to air inlet tube entry position, each cylinder air flue is adjusted, the first series connection twin-inlet 2 to the 4th
Twin-inlet structure of connecting is identical, and the 5th series connection twin-inlet of the 5th cylinder is independent, the double air inlets of the 6th series connection of the 6th cylinder
Road is independent, it is possible thereby to make up because complete machine arrangement causes inlet structure undesirable, each cylinder air inlet stream unevenness is caused to generate
Influence；
2, distal end air intake duct and proximal end inlet structure are distinguish, and in the case where needing to reinforce vortex, reinforce distal end
Air intake duct helical structure weakens the air inlet of proximal end air intake duct, and to ensure under different valve strokes, better whirlpool is formed in cylinder
Rotation ensures that burning is abundant.
The description of the aforementioned specific exemplary embodiment to the present invention is in order to illustrate and illustration purpose.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to the above instruction, can much be changed
And variation.The purpose of selecting and describing the exemplary embodiment is that explaining the specific principle of the present invention and its actually answering
With so that those skilled in the art can realize and utilize the present invention a variety of different exemplary implementation schemes and
Various chooses and changes.The scope of the present invention is intended to be limited by claims and its equivalents.
