Abstract
A silencing fuel oil guide track component is used for resolving problems that fuel oil guide tracks are high in radiation and noise. The technical scheme includes that the silencing fuel oil guide track component consists of a high-pressure oil track assembly and an oil track silencing cover, the high-pressure oil track assembly comprises an oil track, an oil sprayer and a fuel oil distribution pipe joint, wherein the oil sprayer is connected with the oil track, the fuel oil distribution pipe joint is located at one end of the oil track, the oil track silencing cover is provided with a holding groove, and the oil track is located inside the holding groove and covered by the same. On the premise of not affecting arrangement of a total engine, the oil track silencing cover structurally matching with the high-pressure oil track is designed according to surface characteristics of the high-pressure oil track, the high-pressure oil track and the oil track silencing cover form the guide track component, and the oil track silencing cover utilizes multi-pore materials which absorbs large quantities of noise of the oil track, thereby effectively reducing the noise of the oil track. The silencing fuel oil guide track component is skillful in structural design and simple in structure, and can be used for various vehicles provided with high-pressure common tracks.
Description
Technical field
The utility model relates to the noise elimination fuel rail assembly in a kind of the motor car engine parts, particularly engine fuel system, belongs to automobile technical field.
Background technique
With the auto manufacturing technology develop rapidly, automaker is improving constantly for the performance index of each parts of automobile.At present, the diesel engine that automobile uses adopts the high-pressure common rail technology mostly, its oily rail tends to send bigger sound when idling, oil rail noise spreads in the whole cabin very noisy, even shut engine compartment cover, can clearly hear also that in vehicle front and Che Nei it is self-evident that noise is given the adverse effect that driver and environment caused.It is as follows to trace it to its cause: when engine operation, the opening and closing that ECU sends the SC sigmal control oil sprayer realize oil spout, oil sprayer comprises electromagnetic coil and has the needle-valve of armature, during oil spout, ECU makes the electromagnetic coil energising for signal of oil sprayer, produce suction, needle-valve is opened, open the nozzle opening commencement of fuel injection; During outage, magnetic force disappears, and spring presses down needle-valve, closes nozzle opening and stops oil spout.The frequency that above-mentioned needle-valve is closed and opened is very high, constantly gives fuel pressure to finish, and therefore produces fluctuation, and this fluctuation can reach oily rail, excites oily rail wall, thereby produces oily rail noise.
Summary of the invention
The utility model is used to solve the defective of above-mentioned prior art and provides a kind of can effectively be eliminated or the noise elimination fuel rail assembly of fuel rail radiated noise when reducing the electronic fuel injection engine idling.
The alleged problem of the utility model solves by the following technical programs:
A kind of noise elimination fuel rail assembly, its specialization is: it is made up of high pressure oil rail assembly and oily rail sound proof housing, described high pressure oil rail assembly comprises oily rail, the oil sprayer that is connected with oily rail and is positioned at the fuel distribution pipe joint of oily rail one end, described oily rail sound proof housing is provided with the containing groove, described oily rail is positioned at and contains groove, by containing the groove inclusion.
Above-mentioned noise elimination fuel rail assembly, a sidewall of described oily rail sound proof housing are provided with the oblique rank groove with oil sprayer plug outline, are provided with the attached column body that mates with oily rail locating slot in this inside sidewalls.
Above-mentioned noise elimination fuel rail assembly, described containing groove one end sealing, the other end connects, and described fuel distribution pipe joint leans out by containing groove perforation end.
The utility model during at the electronic fuel injection engine idling the big problem of fuel rail radiated noise improve, it designs according to oily rail mechanism of noise generation, under the prerequisite that does not influence whole engine arrangement, design oily rail sound proof housing with its structure matching according to the surface characteristics of high pressure oil rail, both constitute guide assembly, and oily rail sound proof housing adopts the poroelasticity material, and it contains oily rail basically, with the most of absorption of oily rail noise, thereby effectively reduce oily rail noise.The utility model structural design is ingenious, and is simple in structure, can be used in the various vehicles that are equipped with high-pressure common rail.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the high pressure oil rail assembly structural representation;
Fig. 3 is oily rail sound proof housing structural representation.
Label is as follows in the accompanying drawing: 1. oily rail sound proof housing, 1-1. contains groove, the oblique rank of 1-2. groove, 1-3. attached column body, 2. high pressure oil rail assembly, 2-1. oil rail, 2-2. oil sprayer, 2-3. fuel distribution pipe joint, 2-4. oil rail locating slot, 2-5. oil sprayer plug.
Embodiment
Referring to Fig. 1, the utility model is formed by high pressure oil rail assembly 2 with by the oily rail sound proof housing 1 that poroelasticity material such as polyurethane foam sponge are made, oil rail sound proof housing is provided with and contains groove 1-1, the oil rail is positioned at and contains groove, promptly contain groove and take the encirclement mode, thereby fully absorb oily track surface radiated noise oily rail inclusion.
Referring to Fig. 2, high pressure oil rail assembly comprises oily rail 2-1, be positioned at the oil sprayer 2-2 on the oily rail and be positioned at the fuel distribution pipe joint 2-3 of oily rail one end; Referring to Fig. 3, a sidewall of oily rail sound proof housing is provided with the oblique rank groove 1-2 with oil sprayer plug 2-5 outline, is provided with the attached column body 1-3 that mates with oily rail locating slot 2-4 in this inside sidewalls.Contain the end sealing of groove 1-1, the other end connects, and fuel distribution pipe joint 2-3 leans out by containing groove perforation end.The said structure design can make engine wiring harness be connected with the oil sprayer plug 2-5 that is positioned at groove place, oblique rank, and the fuel distribution pipe joint 2-3 that leans out oily rail sound proof housing is connected and then leads to oil pump with fuel hose.
The utility model is under the prerequisite that does not influence whole engine arrangement, with oily rail sound proof housing spiral-lock to high pressure oil rail assembly, the noise that the oil rail produces is absorbed by oily rail sound proof housing, therefore can improve the radiated noise of high pressure oil rail assembly in whole cabin effectively, also can reduce oil sprayer is carried noise from high pressure oil to cylinder simultaneously.
