Description
A Fuel Rail Assembly
Technical Field
The present utility model is directed to a fuel rail assembly, and more particularly, to a fuel rail assembly for use in the automotive engine.
Background Technology
On today's Chinese automobile market, many engine manufacturers use the same engine module design but different air intake manifolds and other accessory engine parts depending on the actual needs. On the other hand, the engines have the same cylinder volume and bore spacing to provide the same injector spacing in the engines, thus making it possible to allow injectors to have the same flow rate.
However, as each model of engine has a different air intake manifold while the fuel rail is fixed to the air intake manifold through the bolt holes in the mounting bracket with bolts, the mounting bracket of each model of engine must be different because it should be mated with the air intake manifold. Similarly, the fuel inlet pipe is mounted to a different area depending on the automobile, which leads to different fuel inlet pipes for the fuel rail in each model of engine. Each engine is equipped with a different mounting bracket and fuel inlet pipe that are fitted in their corresponding locations, which directly results in the impossibility of their sharing the same type of fuel rail.
Up to this point, each different model of engine in an engine family uses a specific fuel rail construction. For the 465 engine that is commonly seen on today's Chinese market, there are 4 major manufacturers in China who produce the 465 engine in 25 models and the total output of this engine is 600,000 units per year.
The fuel rails of these engines are all made of stainless steel and have a mounting bracket and fuel inlet pipe fitted on them through the brazing process. Generally, the output of engines in each particular design is so low that use of cheaper plastic material such as PA66 30-35% glass fiber is out of the question because of the high cost associated with mold development. However, if some of these engines can share the same fuel rail design, the output of such a fuel rail can be greatly increased, making it possible to use more cost-effective plastic material.
Description of the Utility Model
The fuel rail made of stainless steel used in the prior art has a higher cost, and the mounting bracket and fuel inlet pipe of the fuel rail for each type of engine have different constructions, which makes it difficult to use a cheaper material (such as plastic) because of the higher cost of molds designed specifically for the fuel rail for each type of engine .
To solve this problem, the present utility model provides a fuel rail assembly for an automotive engine, which comprises a fuel rail main pipe and a mounting bracket arranged on the fuel rail main pipe, and said fuel rail main pipe is detachably connected to the mounting bracket. The mounting bracket is composed of a top bracket part and a bottom bracket part which are mated with each other. The external circumference of the fuel rail main pipe is provided with ribs which are matched with the grooves of the mounting bracket.
The fuel rail assembly of the present utility model further comprises a fuel inlet pipe connected with the fuel rail main pipe. Said fuel inlet pipe may be connected to the fuel rail main pipe through ultrasonic welding or rotary friction welding, or may be fixed to one end of the fuel rail main pipe with a clamping piece and an 0-ring is provided at the
connecting end of the fuel inlet pipe for sealing.
The fuel rail assembly of the present utility model has several benefits .
Firstly, the mounting bracket and the fuel rail main pipe of the present utility model are detachably connected, and the fuel inlet pipe is connected to the fuel rail main pipe through welding or otherwise by assembling so that these 3 parts of the fuel rail can be manufactured separately, and large-scale production is possible since the same model of engine shares the same type of fuel rail main pipe which matches the injector. In this case, stainless steel can be replaced by a cost-effective material such as plastic in production. As the mold cost per main pipe is greatly reduced, the total cost is lower than the brazed stainless steel component. As a result, the cost of the entire fuel rail will be reduced.
Secondly, the fuel rail has ribs which are mated with the grooves of the mounting bracket, and each rib has a flat portion and each groove has a protruding portion to mate with the flat portion to ensure that the fuel rail main pipe will not move relative to the mounting bracket, thereby improving safety of engine operation.
Thirdly, the fuel rail main pipe, the mounting bracket and the fuel inlet pipe are manufactured separately. In practical application, this allows for the flexibility to select different models of mounting bracket and fuel inlet pipe according to actual needs and assemble them and connect the assembly to the fuel rail main pipe. As a result, the flexibility of fuel rail mounting is greatly enhanced.

Embodiments
The fuel rail assembly of the present utility model will be described in detail below with reference to the drawings.
A fuel rail assembly 10 comprises a fuel rail main pipe 1, a mounting bracket 2 consisting of a top bracket part 2a and a bottom bracket part 2b and a fuel inlet pipe 3. Said fuel rail main pipe 1 is often made of low-cost plastic material such as PA66 30-35% glass fiber.
As shown in Figure 1, the fuel rail main pipe 1 is provided with a plurality of injector connectors 7, and the main pipe has one closed end and one open end. The internal diameter of the mounting bracket 2 corresponds to the external diameter of the fuel rail main pipe 1. For example, as shown in Figure 5 and Figure 8, this can be achieved by having corresponding arcs on both the top bracket part 2a and the bottom bracket part 2b of the mounting bracket 2.
During assembling of the fuel rail assembly 1, in order to securely fit the mounting bracket 2 onto the fuel rail main pipe 1, there are ribs 4 with a protrusion part on the external circumference of the fuel rail main pipe 1, preferably on the center line of the fuel rail bolt hole in the engine, and there are grooves in both of the top bracket part 2a and the bottom bracket part 2b of the mounting bracket 2, as shown in Figure 4 and Figure 7. During mounting, the top bracket part 2a slides into the bottom bracket part 2b, and the bolt hole 23 in the top bracket part 2a coincides with the bolt hole 24 in the bottom bracket part 2b, and the recessing portion 21 of the top bracket part 2a is mated with the protruding portion 22 of the bottom bracket part 2b, and the ribs 4 on the fuel rail main pipe 1 sets into the grooves of the mounting bracket parts 2a, 2b. The arc portions of the top bracket part 2a and the bottom bracket part 2b are combined to correspond to the external diameter of the fuel rail main pipe 1 so as to ensure that the mounting bracket 2 is fixed onto the fuel rail main pipe 1. In the actual production process, the fuel rail main pipe 1 is often provided with two or more ribs 4 of different models to enable the fuel rail main pipe 1 to mate with the mounting
brackets 2 of different models, as shown in Figure 1.
In addition, as illustrated, each rib 4 is provided with a flat portion 41, and each groove of the mounting bracket is provided with a protruding portion 42 to mate with the flat portion 41. The flat portion 41 of different ribs 4 is located in different places, which help the alignment operation that ensures the mounting bracket is fitted to the right place. As such, once the mounting bracket 2 is fitted onto the fuel rail main pipe 1, the fuel rail main pipe 1 will not rotate relative to the mounting bracket 2 by relying on said flat portion 41 and protruding portion 42, which further ensures the firmness of the fuel rail and improves the safety of engine operation.
The fuel inlet pipe 3 of the fuel rail assembly 10 according to the present utility model will be described below with reference to Figure 10 and Figure 11. Figure 10 is a front view of the fuel inlet pipe 3. As shown, one end of the fuel inlet pipe 3 is used to admit fuel, and the other end is connected to the open end of the fuel rail main pipe 1. Said fuel inlet pipe 3 can be made of plastic or stainless steel. The fuel inlet pipe 3 made of plastic can be directly connected with the open end of the fuel rail main pipe 1 through ultrasonic welding or rotary friction welding. When the fuel inlet pipe 3 is made of stainless steel, it is inserted into the corresponding hole in the open end of the fuel rail main pipe 1 and fixed onto the fuel rail main pipe 1 with the clamping piece 5, and there is an O-ring 6 installed onto the fuel inlet pipe 3 to ensure tightness of the connection.
For the material cost of the present utility model, as described above, the fuel rail is an assembly, and the same model of engines can share the same model of fuel rail main pipes so that several types of fuel rails in smaller production quantity can be combined to become a larger production quantity. In this case, the stainless steel material used in
the prior art can be replaced by the plastic material for large-scale production of fuel rail main pipes. In this way, the mold cost per plastic fuel rail is greatly reduced, and the total cost is lower than the brazing stainless steel fuel rail.
The design of the mounting bracket 2 for each engine can be different according to the needs of the air intake manifold and the structure of the mounting bracket 2 is simpler than the fuel rail main pipe 1. According to the present utility model, there is also the need to design a mold for each type of mounting bracket but the cost of this investment is not high due to the simple construction. The mounting bracket 2 can be made of low-cost plastic compound such as PP or ABS.
It is evident that the fuel rail assembly design of the present utility model can allow fuel rails to be produced at a lower cost and increase the mounting flexibility as well.
