Description
Technical Field
The utility model belongs to the technical field of the relevant technique of car high pressure oil rail and specifically relates to an oil spout seat for high pressure oil rail is related to.
Background
The high pressure fuel oil rail of engine is the oil pipeline in front of the oil sprayer for supplying oil to cylinder by internal combustion engine. It includes a fuel inlet and a seat sleeve connected with several fuel injectors, and an oil pressure sensor. With the continuous upgrading of high-pressure technology, 500MPa fuel rails have already been applied to automobiles. However, as the fuel pressure increases, the noise of the fuel system becomes one of the noise sources of the whole vehicle, especially under the idle condition of the whole vehicle, the fuel vibration noise becomes one of the important factors influencing the noise, vibration and sound vibration roughness indexes of the passenger vehicle.
The fuel oil is blocked when the fuel oil injector is closed, and the kinetic energy of the fuel oil at the blocked end is converted into pressure energy to start spreading in the pipeline due to the inertia effect, so that pressure shock waves are formed. In the process of pressure wave propagation, potential energy is converted into kinetic energy, the kinetic energy is gradually attenuated until the kinetic energy is 0 under the friction and deformation action of the fuel oil and the pipe wall of the fuel oil pipeline, but the periodical opening and closing of the fuel injector is continuously carried out all the time, the old potential energy is not attenuated, new potential energy is generated, and the process is repeated, so that periodical pressure pulsation is formed in the fuel oil system, and further fuel oil pressure pulsation noise is generated. As fuel pressure increases, fuel systems have become increasingly noisy and cannot be ignored.
In the design of the existing oil injector seat, after the interior of the oil injector seat is communicated with a main oil pipe, an integrated cavity is almost formed with the main oil pipe of an oil rail, pressure waves are repeatedly transmitted in the main oil pipe and the oil injector seat, the fuel pressure pulsation noise is large, and the oil injector seat is very unfavorable for weakening or inhibiting the pressure pulsation.
SUMMERY OF THE UTILITY MODEL
The present invention is directed to an injector seat for a high pressure oil rail to overcome the above-mentioned drawbacks of the prior art.
The purpose of the utility model can be realized through the following technical scheme:
the oil sprayer seat for the high-pressure oil rail comprises a seat body, wherein an accommodating cavity used for being connected and assembled with an oil sprayer is formed in the seat body, a concave cavity used for being connected and assembled with a main oil pipe of the high-pressure oil rail is formed in the seat body, an inner hole groove is formed in the concave cavity, a noise reduction throttling sheet is arranged in the inner hole groove, and a through hole is formed in the noise reduction throttling sheet.
Further, the diameter of the through hole is 1 mm.
Furthermore, the structure of the noise reduction throttle plate is a torus structure.
Furthermore, the seat body is also provided with a clamping hole for clamping installation.
Further, the clamping holes are symmetrically arranged on the seat body.
Furthermore, the base body is also provided with a clamping groove for clamping installation.
Further, the clamping grooves are symmetrically arranged on the base body.
Furthermore, the bottom of the seat body is also provided with a U-shaped notch for clamping installation.
Compared with the prior art, the utility model has the advantages of it is following:
(1) the utility model discloses increase the throttle piece of making an uproar that falls of a aperture diameter 1mm in the injector seat, can follow all parts and the technology with former design, all do not have the influence to injector seat and oil rail owner oil pipe, produce line transformation and cost increase influence few to high pressure oil rail, nevertheless can reach the very good effect of making an uproar of falling.
(2) The utility model discloses a seat integrated into one piece need not other more auxiliary component, and the cost is lower, and the easier replacement is maintained.
(3) The utility model discloses a throttle plate of making an uproar falls in seat simple installation, its preparation technology is also very simple, and actual ease of use is good.
