Abstract
The utility model discloses a high pressure fuel distribution pipe of a gasoline engine, which comprises a main oil pipe; an oil injector seat, a high pressure oil pipe connector and a sensor connector are arranged on the main oil pipe; a plurality of fixing brackets which are formed by punching are also arranged on the main oil pipe; the fixing brackets are provided with arc interconnecting pieces which correspond to the outer wall of the main oil pipe; the interconnecting pieces are used for connecting and fixing the fixing brackets and the main oil pipe; and fixing parts which fix the fixing brackets together with the main oil pipe on the gasoline engine are also arranged on the fixing brackets. By adopting a plurality of fixing brackets which are formed by punching, the material cost and the process cost of the high pressure fuel distribution pipe of the gasoline engine are greatly reduced; and each fixing bracket can be flexibly installed; and the high pressure fuel distribution pipe can adapt to the application of engines with different structures.
Description
Technical field
The utility model relates to a kind of part of high pressure gasoline motor, especially a kind of gasoline engine high pressure fuel distribution pipe.
Background technique
Along with development of technology, latest developments go out a kind of novel high compression engine, and gasoline has very big pressure in inflow engine.This motor is compared with motor before, can export bigger power, and makes the combustion efficiency of fuel higher.The structure of the fuel dispensing tube of existing this high compression engine comprises main oil pipe 1, backbone block 2, oil injector seat 3, high-pressure oil pipe joint 4, high pressure sensor joint 5 as shown in Figure 1.Support that wherein piece 2 is to make by casting technique or whole process for machining.The high pressure fuel distribution pipe that also has now is to adopt the integrated type pressed plate that main oil pipe is fixed.Existing high pressure fuel distribution pipe is because the system pressure height that uses can reach 200 kilograms.For proof strength, generally all can adopt the fuel dispensing tube of above-mentioned two kinds of structures.The cost of material and the technology cost of two kinds of above structures are all very high, and structure is also relatively heavier, can not be applicable to the motor of various different structures.
The model utility content
Technical problem to be solved in the utility model provides a kind of gasoline engine high pressure fuel distribution pipe, can reduce the cost of material and the technology cost of gasoline engine high pressure fuel distribution pipe, and can be suitable for the engine application of various different structures.
For solving the problems of the technologies described above, the technological scheme of the utility model gasoline engine high pressure fuel distribution pipe is, comprise main oil pipe, described main oil pipe is provided with oil injector seat, high-pressure oil pipe joint and sensor connector, also be provided with a plurality of fixed supports that are stamped to form on the described main oil pipe, joint with the corresponding circular arc of main oil pipe outer wall is arranged on the described fixed support, described joint is used for described fixed support and described main oil pipe are connected and fixed, and also is provided with on the described fixed support described fixed support is fixed on fixing part on the petrol engine together with main oil pipe.
The utility model adopts a plurality of fixed supports that are stamped to form, and greatly reduces the cost of material and the technology cost of gasoline engine high pressure fuel distribution pipe, and each fixed support can install flexibly, can adapt to the application of the motor of different structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail:
Fig. 1 is the structural representation of existing gasoline engine high pressure fuel distribution pipe;
Fig. 2 is an embodiment's of the utility model gasoline engine high pressure fuel distribution pipe a structural representation;
Fig. 3 is a support bracket fastened structural representation in the utility model;
Fig. 4 is another embodiment's of the utility model gasoline engine high pressure fuel distribution pipe a structural representation.
Reference character is among the figure, 1. main oil pipe; 2. support piece; 3. oil injector seat; 4. high-pressure oil pipe joint; 5. high pressure sensor joint; 6. fixed support; 7. joint; 8. fixing part; 9. stiffening rib.
Embodiment
The utility model discloses a kind of gasoline engine high pressure fuel distribution pipe, as shown in Figure 2, comprise main oil pipe 1, described main oil pipe 1 is provided with oil injector seat 3, high-pressure oil pipe joint 4 and sensor connector 5, also be provided with a plurality of fixed supports that are stamped to form 6 on the described main oil pipe 1, as shown in Figure 3, joint 7 with the corresponding circular arc of main oil pipe 1 outer wall is arranged on the described fixed support 6, described joint 7 is used for described fixed support 6 and described main oil pipe 1 are connected and fixed, and also is provided with on the described fixed support 6 described fixed support 6 is fixed on fixing part 8 on the petrol engine together with main oil pipe 1.Described fixed support 6 is provided with stiffening rib 9, in order to increase the intensity of fixed support 6.
As shown in Figure 2, described fixed support 6 is arranged at a side of described main oil pipe 1.
Described fixed support 6 can also be arranged at the both sides of described main oil pipe 1, as shown in Figure 4.
When making the utility model gasoline engine high pressure fuel distribution pipe, make described fixed support with the method for punching press earlier, afterwards described a plurality of fixed supports are welded on the described main oil pipe.
Compare with the high pressure fuel distribution pipe of existing employing foundry goods fixed block, the employed material of the utility model fixed support will reduce many, and the stamping process cost compare with the casting technique cost also can be much lower.Compare with the fixed structure of existing integrated type pressed plate, the support bracket fastened joint of the utility model is and the corresponding circular arc of main oil pipe outer wall, therefore in fixed support and main oil pipe connection, the link position of each fixed support and main oil pipe outer wall can be regulated around the axis of main oil pipe, with the needs of the motor that adapts to different structure, and existing integrated type pressed plate fixed structure just can not be regulated like this.
In sum, the utility model adopts a plurality of fixed supports that are stamped to form, and greatly reduces the cost of material and the technology cost of gasoline engine high pressure fuel distribution pipe, and each fixed support can install flexibly, can adapt to the application of the motor of different structure.
