Background technique
At present, conventional gas engine all adopts single-point and multi-point gas spraying technique, assembles after its cylinder head, intake manifold, independent design again.Such design, have part many, install very complicated, power system total quality heavy, compact not attractive in appearance, structural strength is bad, sealing badly has gas leakage hidden danger; After long-time running, spot check needs to change air inlet pad, and versatility is not high, and single-point or multi-point injection need to adopt different cylinder caps and intake manifold, and same type needs exploitation two kinds of cylinder caps, and development cost is high.
Model utility content
Not enough for prior art, technical problem to be solved in the utility model is to provide a kind of gas engine cylinder cap, and intake manifold is integrated in cylinder head by it, reduces installation procedure, improves the intensity of gas-entered passageway.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is:
A kind of gas engine cylinder cap, comprise cylinder head, be provided with intake manifold and gas mixing chamber in described cylinder head, described cylinder head and intake manifold and gas mixing chamber are structure as a whole, intake manifold is provided with gas injection nozzle aperture, and corresponding intake manifold one end is provided with air inlet.
Further, described intake manifold horizontal integrating is in cylinder head.
Described gas injection nozzle aperture is one group that is arranged side by side.
Described gas injection nozzle aperture is one, and corresponding air inlet is arranged.
Also comprise the combustion gas mixing adapter of accessible site in cylinder head, combustion gas mixing is taken over one end and is connected with the gas mixing chamber in cylinder head, and the combustion gas mixing adapter the other end is air inlet, and gas injection nozzle aperture is located in combustion gas mixing adapter.
Described one group is arranged side by side a gas injection nozzle aperture corresponding cylinder machine firing chamber respectively.
The utility model compared with prior art, has the following advantages:
1, be a part by cylinder head integrated intake manifold, gas mixing chamber, effectively reduce engine part quantity, reduce installation procedure, promote total quality, compact structure;
2, be integrated in cylinder head by intake manifold, make intake manifold and cylinder head intensity suitable, significant increase admission manifold branch structure intensity, the detonation can born with firing chamber is the same is impacted, strengthen intake manifold reliability;
3, for multi-point injection gas engine, intake manifold is integrated in cylinder head, intake manifold is suitable with cylinder head intensity, intake manifold can arrange calmly gas injection nozzle, the little cylinder diameter high power engine of effective solution high speed, should spark plug be arranged in cylinder cap, arrange that the space of gas injection nozzle is awkward again;
4, for single-point discharge gas engine, by intake manifold, gas mixing chamber is integrated or be embedded in cylinder head, decrease combination gas passage length, namely firing chamber is entered through extremely short passage after combustion gas effectively mixes, burning responsiveness is better, the detonation that intake manifold can be born with firing chamber is the same is simultaneously impacted, the harm that after effectively reducing fuel gas mixture leakage, tempering is blown out, and Security is higher;
5, intake manifold is integrated in cylinder head, the gas injection nozzle aperture of reserved multi point injection engine on the gas-entered passageway wall that each combustion chamber charge road is corresponding, combustion gas mixing intake duct or the mixing chamber of single-point discharge motor is reserved in air inlet siphunculus both sides or side, realize the same blank of cylinder cap of single-point and multi point injection engine, even same cylinder cap, significantly reduces costs.
Accompanying drawing explanation
Below the content expressed by each width accompanying drawing of this specification and the mark in figure are briefly described:
Fig. 1 is the utility model gas engine cylinder cap schematic diagram one.
Fig. 2 is the utility model gas engine cylinder cap schematic diagram two.
Fig. 3 is the utility model gas engine cylinder cap schematic diagram three.
Fig. 4 is the utility model gas engine cylinder cap schematic diagram four.
In figure: 1. gas injection nozzle aperture group, 2. single-point gas injection nozzle aperture, 3. air inlet, 4. single-point discharge gas mixing chamber, 5. cylinder machine combustion chamber placement position, 6. combustion gas mixing adapter.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is described in further detail.
As shown in Figures 1 to 4, this gas engine cylinder cap, comprises cylinder head, intake manifold and gas mixing chamber, intake manifold and gas mixing chamber are integrated in cylinder head, the as a whole structure of three, intake manifold is provided with gas injection nozzle aperture, and corresponding intake manifold one end is provided with air inlet 3.
Wherein, intake manifold horizontal integrating is in cylinder head; Gas injection nozzle aperture is that the gas injection nozzle aperture group 1, a group be arranged side by side is arranged side by side a gas injection nozzle aperture corresponding cylinder machine firing chamber respectively, and form multipoint injection system, each gas injection nozzle aperture is all corresponding to a cylinder machine combustion chamber placement position 5.
Or gas injection nozzle aperture is a single-point gas injection nozzle aperture 2, corresponding air inlet is arranged, and forms single-point discharge gas mixing chamber 4 in the cylinder head of corresponding single-point gas injection nozzle aperture and air inlet, forms single-point discharge system; Cylinder head is gone back accessible site and arrange a combustion gas mixing adapter 6, combustion gas mixing is taken over one end and is connected with the gas mixing chamber in cylinder head, and the combustion gas mixing adapter the other end is air inlet, and the gas injection nozzle aperture of single-point is located in combustion gas mixing adapter.
Novel gas engine cylinder cover integrated intake manifold and gas mixing chamber, novel gas engine cylinder cover can effectively reduce engine part quantity, reduces installation procedure, reduces total quality, compact attractive in appearance.
