Abstract
This utility model relates to technical field of automobile engine, particularly relate to a kind of high pressure oil rail, described oil rail body (1) side is sequentially provided with multiple fixture (2), and described fixture (2) is provided with the fixed bolt hole (3) for being fixed on cylinder cap by oil rail body (1), and it is additionally provided with the mounting hole of oil sprayer (4) for fixing fuel injector on described fixture (2), it is characterized in that: it also includes fuel pump, and described fuel pump is arranged on oil rail body (1) opposite side and one-body molded with oil rail body (1).By fuel pump and oil this body by integral forming of rail, it is more convenient for so making, it is not necessary to be divided into two part manufactures, manufacturing cost is relatively low, and need not between the two be mounted with, not only increases efficiency, and because decrease the support needed for installation, so overall weight is lighter.
Description
Technical field
This utility model relates to technical field of automobile engine, particularly relates to a kind of high pressure oil rail.
Background technology
Along with the development of automobile engine industry, energy-saving and emission-reduction are the Main way of current engine research, development, electromotor zero
Parts are progressively to lightweight, simplification development.Prior art high pressure oil rail and fuel pump are all single parts, need individually system
Making, such manufacturing cost is higher, and fuel pump needs fix by being arranged on support extra on high pressure oil rail, install number
Tired, and overall weight is heavier.
Summary of the invention
Technical problem to be solved in the utility model is: provide the high pressure oil rail of a kind of integrated fuel pump.
This utility model be the technical scheme is that a kind of high pressure oil rail, including the oily rail body of oval tubulose, described
Oil rail body side is sequentially provided with multiple fixture, and described fixture is provided with for being fixed on cylinder cap by oil rail body
Being additionally provided with the mounting hole of oil sprayer for fixing fuel injector on fixed bolt hole, and described fixture, it also includes fuel pump, and
Described fuel pump be arranged on oil rail body opposite side and with oil this body by integral forming of rail.
Using above structure compared with prior art, this utility model has the advantage that fuel pump and oil rail body
One-body molded, it is more convenient for so making, it is not necessary to being divided into two part manufactures, manufacturing cost is relatively low, and between the two
Need not be mounted with, not only increase efficiency, and because decrease the support needed for installation, so overall weight is lighter.
As preferably, described fuel pump is additionally provided with one section of boss with oil this body by integral forming of rail place.So it is arranged on and makes
Obtaining the structural strength between fuel pump and oil rail body higher, fuel pump is not easy to come off from oil rail body.
As preferably, described fuel pump includes fuel pump body and the rhombus fixed block being arranged on fuel pump body,
And described fixed block is provided with the fuel pump fixing hole for being fixed on cylinder cap by fuel pump apart from farthest both sides.At fuel pump
On the fixed block of a rhombus is set, and be fixed on cylinder cap by fixed block, after such integral installation, fuel pump is less
Easily come off.
As preferably, described fuel pump body is provided with automatically controlled interface away from oil rail body side.So arrange and can allow electricity
Control interface, away from oil rail body, i.e. makes fuel pump wiring more convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model high pressure oil rail.
As shown in the figure: 1, oil rail body；2, fixture；3, fixed bolt hole；4, mounting hole of oil sprayer；5, boss；6、
Fuel pump body；7, fixed block；8, fuel pump fixing hole；9, automatically controlled interface.
Detailed description of the invention
With detailed description of the invention, this utility model is described further below in conjunction with accompanying drawing, but this utility model is not only
It is limited to detailed description below.
A kind of high pressure oil rail, including the oily rail body 1 of oval tubulose, described oil rail body 1 side is sequentially provided with multiple solid
Locking member 2, and described fixture 2 is provided with for by the oil fixed bolt hole 3 that is fixed on cylinder cap of rail body 1 and described fixing
Being additionally provided with the mounting hole of oil sprayer 4 for fixing fuel injector on part 2, it also includes fuel pump, and described fuel pump is arranged on oil
Rail body 1 opposite side and with oil rail body 1 one-body molded.
Described fuel pump is additionally provided with one section of boss 5 with the oil one-body molded place of rail body 1.
Described fuel pump includes fuel pump body 6 and the rhombus fixed block 7 being arranged on fuel pump body 6, and described
Fixed block 7 is provided with the fuel pump fixing hole 8 for being fixed on cylinder cap by fuel pump apart from farthest both sides.
Described fuel pump body 6 is provided with automatically controlled interface 9 away from oil rail body 1 side.And it is additionally provided with low on fuel pump body 6
Compression ignition oil interface.
