Abstract
The utility model belongs to the technical field of the technique of internal -combustion engine and specifically relates to a single cylinder diesel engine cylinder lid. A single cylinder diesel engine cylinder lid, has the combustion chamber of setting in the cylinder head, the top surface of combustion chamber has the injector orifice, the injector orifice below is equipped with the minor air cell rather than communicating cavity shape, the minor air cell below is combustion chamber, is equipped with the glow plug in the minor air cell, and the minor air cell below has the communicating passageway with combustion chamber, is equipped with the heat insulating block on this passageway. The utility model discloses work is steady, harmful gas discharges less, to the fuel and atomize insensitively, simultaneously, owing to installed glow plug and heat insulating block, improved the hot state of combustion chamber, improved the starting performance, reasonable in design ensures high -quality production demand.
Description
Technical field
This utility model relates to the technical field of internal combustion engine, especially a kind of single cylinder diesel cylinder cap.
Background technology
The gray iron of diesel engine is two parts that in diesel engine, shape is the most complicated, prescription is the highest, because they collectively constitute combustor, bears the heat of combustion gas and the repeated stock of high pressure. They generally all use the method for casting to produce, and for keeping the reasonability of casting technique, first structurally to reduce wall thickness variation, thermal center and wedge angle, in order to typing, molding etc. At present, the high speed of small diesel engine becomes the target that the sector is pursued, therefore needs appropriate design gray iron structure, to meet the demand of high quality of production.
Utility model content
The technical problems to be solved in the utility model is: based on the problems referred to above, it is provided that a kind of single cylinder diesel cylinder cap reasonable in design.
This utility model solves its technical problem and be the technical scheme is that a kind of single cylinder diesel cylinder cap, there is the combustor being arranged in cylinder head, the end face of described combustor has injector orifice, described injector orifice is connected with the minor air cell of the cavity shape communicated therewith, it it is main chamber below described minor air cell, being provided with glow plug in minor air cell, have the passage communicated with main chamber below minor air cell, this passage is provided with heat insulating block.
The beneficial effects of the utility model are: utility model works is steady, noxious gas emission is few, to fuel oil and be atomized insensitive, simultaneously as be mounted with glow plug and heat insulating block, improve the Warm status of combustor, improve starting performance, reasonable in design, it is ensured that high-quality Production requirement.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1. combustor, 2. main chamber, 3. heat insulating block, 4. glow plug, 5. minor air cell, 6. injector orifice, 7. passage.
Detailed description of the invention
Presently in connection with accompanying drawing, this utility model is described in further detail. These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the composition relevant with this utility model.
As shown in Figure 1, a kind of single cylinder diesel cylinder cap, there is the combustor 1 being arranged in cylinder head, the end face of combustor 1 has injector orifice 6, injector orifice 6 is connected with the minor air cell 5 of the cavity shape communicated therewith, and is main chamber 2, is provided with glow plug 4 in minor air cell 5 below minor air cell 5, having the passage 7 communicated with main chamber 2 below minor air cell 5, this passage 7 is provided with heat insulating block 3.
The mixed Daqu of the combustor 1 of the present embodiment mainly utilizes air-flow whirling motion method, twice whirling motion: compression and burning whirling motion, the requirement of combustion jet system and work quality thereof is decreased, required excess air coefficient is also only small, strengthen owing to compression eddy flow raises with rotating speed, add and be mounted with glow plug 4 and heat insulating block 3, improve the Warm status of combustor 1, improve starting performance, so being suitable for the high speed of small diesel engine.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not necessarily departing from this utility model technological thought, can carry out various change and amendment completely. The technical scope of this utility model is not limited to the content in description, it is necessary to determine its technical scope according to right.
