In order to achieve the above object, the present invention is realized as follows: an electronic fuel rail assembly, comprising: including tee bend oil duct and oil rail overcoat, the axis of wherein two oil ducts of tee bend oil duct is located same straight line, the oil rail overcoat is two and rotatably overlaps respectively and establish the outer wall at two oil ducts that are located same straight line, the oil rail overcoat have with the communicating oil pocket of oil duct. By adopting the electronic fuel injection rail assembly arranged in the mode, after the fuel rail outer sleeve is fixedly installed on the double-cylinder valve body, the connector of the three-way oil passage can rotate, the length of the fuel rail assembly can be adjusted according to the distance between the double-cylinder valve body, the universality of the electronic fuel injection rail assembly is improved, and the matching of an engine and the matching of electronic fuel injection accessories can be realized by carrying multiple vehicle types.
Further, a sealing ring is arranged between the inner wall of the oil rail outer sleeve and the outer wall of the oil duct.
Furthermore, the oil rail outer sleeve is provided with an oil duct interface connected with the valve body.
Preferably, the outer wall of the oil rail outer sleeve is further provided with a support lug, and the support lug is provided with a mounting hole.
Preferably, the other oil passage of the three-way oil passage is a middle oil passage and is perpendicular to the two other oil passages which are positioned on the same straight line.
Preferably, one ends of the two oil ducts which are positioned on the same straight line and close to the middle oil duct are respectively provided with a limiting boss.
Preferably, the oil rail outer sleeve in the utility model is a plastic part.
Has the advantages that:
the utility model discloses the rotatability of kneck has been realized to electricity spouts oil rail subassembly, can satisfy the variety of whole car overall arrangement, makes the supporting electricity of same kind double-cylinder engine spout the annex and carry on multiple motorcycle type and become possible. Experiments prove that by adopting the rotatable plastic electronic injection oil rail assembly structure, an engine can be matched with the same set of electronic injection accessories to carry various vehicle types. The disadvantage that the universality of the traditional oil rail is low is made up, the universality of the electric injection accessory is improved, and the development cost of the electric injection accessory is reduced. The issuing of the electronic fuel injection rail has an unusual significance for the same model needing to be equipped with different models.
In addition, the rotatable plastic electric injection oil rail assembly can enable electric injection accessories to be generalized on the basis of a traditional electric injection oil injector pressure cap, and the plastic molding product is high in accuracy and can meet the sealing requirement of an oil way.

Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings, but the present invention is not limited to these embodiments, and any modifications or replacements within the basic spirit of the embodiments still fall within the scope of the present invention claimed in the claims.
Example (b): as shown in fig. 1-3, the present embodiment provides an electronic fuel injection rail assembly, which is suitable for a two-cylinder engine, and is used for connecting with an oil inlet of a two-cylinder valve body 3 on the engine, and externally connecting with an oil tank to deliver fuel into an engine cylinder.
The method specifically comprises the following steps: the utility model provides an electricity spouts oil rail subassembly, includes tee bend oil duct 1 and oil rail overcoat 2, wherein two oil duct 11's of tee bend oil duct axis is located same straight line, oil rail overcoat is two and rotatably overlaps respectively and establish the outer wall at two oil ducts that are located same straight line, oil rail overcoat have with the communicating oil pocket of oil duct.
The oil rail outer sleeve in the embodiment comprises a cylindrical cavity used for wrapping the outer wall of the oil duct, and further comprises an interface part connected with the oil inlet of the double-cylinder valve body. In addition, the outer wall of the oil rail outer sleeve is also provided with a support lug 21 which extends outwards, and the support lug is provided with a mounting hole 22. The mounting hole is matched with a threaded hole in the double-cylinder valve body, and the oil rail outer sleeve is fixed on the double-cylinder valve body through a screw.
Two oil passages located on the same straight line in the three-way oil passage in the embodiment have outlets in opposite directions, and a third oil passage, namely the middle oil passage 12 is arranged in the middle of the two oil passages, and the middle oil passage is perpendicular to the other two oil passages. And the middle oil passage is used for being connected with the oil tank.
Since the oil passage 11 in this embodiment is rotatably covered in the oil rail jacket, the interface of the intermediate oil passage is circumferentially rotatable. Therefore, the engine can be matched with the same set of electronic fuel injection accessories to carry various vehicle types.
In addition, a sealing ring 4 is arranged between the inner wall of the oil rail jacket and the outer wall of the oil duct in the embodiment. And limiting bosses 13 are respectively arranged at one ends of the two oil ducts which are positioned on the same straight line and are close to the middle oil duct. The oil duct is sealed through the sealing ring, and the oil rail jacket is limited through the limiting boss.
That is to say, do not adopt fixed connection between oil duct and the oil rail overcoat, but adopt the sealing washer to seal, so guaranteed that the interface of middle oil duct can carry out axial rotation, adapts to different models of style motorcycle types.
In addition, the oil rail outer sleeve is fixed with the double-cylinder valve body through a screw and a connector, and is limited through a limiting boss.
As one of the implementation manners in this embodiment, the oil rail jacket is a plastic part, and the plastic part is high in cost, fast in forming, high in precision, and good in sealing effect.
The electronic fuel injection rail assembly realizes the rotatability at the interface, can meet the diversity of the whole vehicle layout, and makes it possible for the electronic fuel injection accessories matched with the same double-cylinder engine to carry various vehicle types. Experiments prove that by adopting the rotatable plastic electronic injection oil rail assembly structure, an engine can be matched with the same set of electronic injection accessories to carry various vehicle types. The disadvantage that the universality of the traditional oil rail is low is made up, the universality of the electric injection accessory is improved, and the development cost of the electric injection accessory is reduced. The issuing of the electronic fuel injection rail has an unusual significance for the same model needing to be equipped with different models.
