Abstract
The utility model relates to a part of an engine, in particular to a fuel guide rail assembly fueling a plurality of oil injectors of the engine. The fuel guide rail assembly comprises an oil rail provided with an oil inlet, a plurality of rigid connecting blocks which are fixedly connected between the oil rail and the oil injectors and communicate the oil rail with the oil injectors are arranged on the oil rail at intervals, and mounting holes for being connected with a body of the engine are arranged on at least two of the connecting blocks. The oil rail and the oil injectors are connected by the connecting blocks, and accordingly fuel leakage caused in demounting of high-pressure pipes is avoided. In addition, the mounting holes are arranged on the connecting blocks, and accordingly stability of the fuel guide rail assembly can be increased, the oil rail is prevented from vibration, and noise is eliminated.
Description
Technical field
The utility model relates to a kind of engine components, and specifically relating to a kind of is the fuel rail assembly of a plurality of oil sprayer fuel feeding of motor.
Background technique
Fuel rail assembly is that very important parts in the motor of oil sprayer are housed, and it is connected with a plurality of oil sprayers of motor, is used for the fuel oil of high pressure is delivered to oil sprayer, burns so that fuel oil is sprayed in the cylinder by oil sprayer.Existing fuel rail assembly comprises the oily rail of a tubulose, is provided with filler opening and the Duo Gen high-voltage tube that enters for fuel oil at oily rail, if these high-voltage tubes are changed the improper fuel leakage that is easy to cause.Also be provided with laminar mounting ear on oily rail, the installation that is used for oily rail and motor is fixed, because the rigidity of mounting ear is lower, so that oily rail easily produces vibration after installation, makes a noise.
The model utility content
For solving the deficiencies in the prior art, the utility model provides a kind of fuel rail assembly, when having avoided leakage, has eliminated the noise of oily rail vibration.
For achieving the above object, fuel rail assembly of the present utility model, comprise the oily rail that is provided with filler opening, be provided with a plurality of be fixed between oily rail and the oil sprayer and with the contiguous block of the rigidity of oily rail and oil sprayer conducting in spacing on the oily rail, be provided with the mounting hole that is connected for engine body at two contiguous blocks at least wherein.
As to restriction of the present utility model, be equipped with mounting hole at each contiguous block.
As to restriction of the present utility model, described mounting hole is arranged on the same position at corresponding contiguous block top.
As to restriction of the present utility model, described contiguous block is for equidistantly be arrangeding in parallel.
As to restriction of the present utility model, be provided with in one of them end of oily rail the oil pressure in the oily rail is responded to.
As to restriction of the present utility model, described filler opening is arranged at the middle part of oily rail.
Adopt as above technological scheme, its effect is as follows: adopt contiguous block to connect oily rail and oil sprayer, the fuel leakage that has caused when having avoided the dismounting high-voltage tube, simultaneously, at contiguous block mounting hole is set, can increases the stability of this fuel rail assembly, avoid oily rail vibration-generating, thereby eliminated noise; Mounting hole all is set on each contiguous block, can further improves the stability of installation; Contiguous block spaced set and mounting hole are arranged on the same position of contiguous block, are convenient to make; At oily rail rail pressure sensor being set is convenient to the oil pressure in the oily rail is measured; Filler opening is arranged at the middle part of oily rail, so that the oil pressure of each oil sprayer approaches unanimously.
Description of drawings
Below in conjunction with the drawings and the specific embodiments the utility model is done further to describe in detail:
Fig. 1 is structural representation of the present utility model.
Among the figure: 10-oil rail, 11-filler opening, 12-rail pressure sensor, 20-contiguous block, 21-mounting hole, 30-oil sprayer.
Embodiment
As shown in Figure 1, fuel rail assembly of the present utility model, include the oily rail 10 of a tubulose, the middle part of oil rail 10 is provided with the filler opening 11 that enters for fuel oil, one of them end at oily rail 10 is provided with rail pressure sensor 12, is used for the real-time master control computer that passes to automobile of oil pressure pressure in the oily rail 10.
At the oily rail 10 equal intervals contiguous block 20 that a plurality of and oily rail 10 is connected that be arranged in parallel, this contiguous block 20 is connected respectively with oily rail 10 and oil sprayer 30, and by the inner pipeline that arranges oily rail 10 and oil sprayer 30 is communicated with.All contiguous blocks 20 all are made as and be arranged in parallel, so not only are convenient to make, and have reduced cost, and owing to saved the space, so that fuel rail assembly can also be installed in the top of motor.
Be provided with mounting hole 21 at least two contiguous blocks 20, this mounting hole 21 is used for passing bolt so that this fuel rail assembly is connected in engine body.In order to improve the stability after fuel rail is installed, attachment hole 21 can all be set on the same position of each contiguous block 20, in order to insert many bolts, thereby avoided reliably the vibration of fuel rail assembly, eliminated noise.
