Description
Technical field
The invention belongs to technical field of engines, is related to a kind of fuel filter of high-efficiency exhaust.
Background technology
It is well known that in order to ensure the high-precision parts such as injection pump in engine fuel oil system, fuel injector, fuel nozzle
Not by fuel oil impurity wear, avoid engine performance export be affected, therefore engine all can on fuel pipe cloth
Put one or several fuel filters.The effect of fuel filter be by filter inside filter paper, to miscellaneous in fuel oil
Matter is filtered, it is ensured that above-mentioned part will not be blocked or wear by flowing into injection pump and particle in fuel injector and impurity；So as to carry
The service life of high above-mentioned parts.
In three standard period of complete machine emission level state of enforcement, since engine emission levels are low, when fuel system works, spray
The operating pressure of oil system is not above 1200bar.This precision and combustion to injection pump of engine, fuel injector inner couplings part
Luboil cleanness requires also not high.Engine fuel oil system parts can adapt to the fuel oil product after plain filter filters
Matter.In this case, as long as it is sufficient that fuel filter can meet the filtering requirement to combustion well cuts, large particulate matter.
The filter cartridge construction of fuel filter is simple, and the filter paper venting capability used can be very strong.In engine operation process intermediate fuel oil
Air in system can be easy to be drained, will not be because gathering many air in oil circuit, and cause what engine operation was stopped working
Problem.
However, as environmental requirement is higher and higher, Abgasgesetz is more and more tighter, the operating pressure of engine fuel oil system
It is continuously improved, is gradually promoted to 1800-2000bar at present.In order to adapt to high workload pressure, injection pump of engine and oil spout
The inner couplings part precision of device is also higher and higher.This just proposes higher to fuel filter to the filtering requirement of impurity in fuel
Requirement.Because some tiny particles and impurity may cause whole fuel system to block, engine work is influenced.
And fuel filter is to improve the filtering to fine particle, it is necessary to increase the consistency of filter paper, to reduce the logical of molecule
The property crossed.After the lifting of filter paper consistency, the gas permeability between filter paper just reduces, so as to cause the air in filter to be not easy meeting
Discharge.And if air is cumulative in fuel system, the amount of fuel that will result in into engine tails off, so as to cause to send out
There is operation and stops working and hard-to-start phenomenon in motivation.
If Fig. 1 is prior art fuel filter cut-away view.When fuel oil enters filter, directly by filter core one end
By filtering, into inside filter core.In the low emission stage, filter core gas permeability is strong, and the air in fuel oil is easy to pass through filter paper.No
Air can be caused to occur accumulation problem inside filter, cause oil circuit short circuit problem occur.It is but right as emission request upgrades
The filtering requirement of filter paper is higher and higher, and the gas permeability of filter paper is worse and worse.Caused consequence is exactly to be discharged in fuel oil
Air cannot be constantly accumulated in the space between filter paper outer end and housing quickly through filter paper.Air meeting in cumulative process
Fuel level is pushed, causes to tail off by the amount of fuel of filter paper in the unit interval, and one is formed in the cavity after filter paper filtering
Fixed vacuum.After air is accumulated to a certain extent, the chamber vacuum degree after filter paper filtering can hinder the normal fuel injection of oil pump,
The amount of fuel for causing entry into oil pump tails off even without so as to cause engine operation flame-out.In addition, acted in fuel pressure
Under, a part of gas before filtering can press through filter paper by pressure, after this partial air is by filter paper, can assemble to form a glob of sky
Gas.If agglomerate air is continuously entered in oil pump, engine will run flame-out because of oil pump oil starvation.If in engine
After shutdown, there is agglomerate air to enter oil pump, can not because air is full of inside oil pump or in oil pipe in engine startup next time
It is normal to start.
The information for being disclosed in the background section is merely intended to understanding of the increase to the general background of the present invention, without answering
It has been the prior art well known to persons skilled in the art when being considered as recognizing or implying the information structure in any form.
The content of the invention
