Oil.
Additionally, above-mentioned engine fuel system, is protected by the deleterious particle impurity and water effective in removing diesel oil
The accurate coupling part of oil supply system, for example, minimum mechanical admixture causes plunger matching parts, pintle nozzle match-ing parts, metering-orifice in 3-5 μm of level fuel oil
The moving components such as nozzle such as pull, abrade at the abrasive wear, and above-mentioned oil supply system can be prevented effectively from heel and toe wear, so as to prolong
The service life of electromotor is grown.
Above-mentioned fine filter 42, fine cleaner 41 are mainly used in filter 23～5 μm, 5～10 μm of particulate matter.Preferably, essence is filtered
Degree reaches 3-5 μm of ＞ 98.5%, 5-10 μm of ＞ 99.5%.Fine filter, the concrete volume of fine cleaner, filtering accuracy and intensity can be with
Appropriate change is done according to the difference of service condition, but these appropriate changes not affect whole oil supply system to reach above-mentioned basic
Beneficial effect, does further preferably, it is possible to obtain the higher oil product of cleannes to specific filtering accuracy, volume etc., so that
The indices of automobile emission gas are better than state III, the index of state IV.For example, under preferable road conditions and oil product environment：
Light-duty Vehicle：Based on using the km of B10 life-spans 300,000, it is desirable to during granule >=5 μm, filter efficiency >=78%；Granule >=10 μ
During m, filter efficiency >=93%.
Medium Truck：Based on using the km of B10 life-spans 500,000, it is desirable to during granule >=5 μm, filter efficiency >=88%；Granule >=
When 10 μm, filter efficiency >=97%.
Heavy truck：Based on using the km of B10 life-spans 1,000,000, it is desirable to during granule >=5 μm, filter efficiency >=93%；Granule >=
When 10 μm, filter efficiency >=98%.
Under poor road conditions and oil product environment：
Light-duty Vehicle：Based on using the km of B10 life-spans 300,000, it is desirable to during granule >=5 μm, filter efficiency >=96.5%；Granule >=
When 10 μm, filter efficiency >=99%.
Medium Truck：Based on using the km of B10 life-spans 500,000, it is desirable to during granule >=5 μm, filter efficiency >=98%；Granule >=
When 10 μm, filter efficiency >=99.5%.
Heavy truck：Based on using the km of B10 life-spans 1,000,000, it is desirable to during granule >=5 μm, filter efficiency >=99%；Granule >=
When 10 μm, filter efficiency >=99.8%.It can be seen that, in the presence of a harsh environment, the filtering requirement of heavy truck is relatively higher.
Again for example, for the filtering accuracy of monoblock pump and common rail system (four-cylinder), fine filter and fine cleaner meets：3～5
Filter efficiency >=95% of μm granule；Filter efficiency >=98% of 5～10 μm of granules.For common rail system, in the presence of a harsh environment
Heavy goods vehicles are met with type filtering accuracy：Filter efficiency >=98.5% of 3～5 μm of granules；The filter efficiency of 5～8 μm of granules >=
98.9%；Filter efficiency >=99.6% of 8～10 μm of granules.The filter material of filtration can select two-layer compound filter material.
Further for example, for power is in the diesel engine of 110kW or so, in metered flow point, pressure drop control 12kPa with
Under.Flow in common rail pipe needs to reach more than 0.8L in 200L/h or so, the then volume of fine filter.For power is in 220kW
The diesel engine of left and right, in metered flow point, pressure drop is controlled in below 15kPa.Flow in common rail pipe in more than 450L/h, then
The volume of fine filter needs to reach more than 1.6L.
In further embodiment, overfall 63 and pressure limiting valve 64 are additionally provided with common rail pipe, overfall 63 enters with fuel tank
Mouth 11 connects.
Overfall and pressure limiting valve are set on common rail pipe, when the maximum that the pressure of common rail pipe intermediate fuel oil exceedes pressure limiting valve is born
During power, pressure limiting valve is opened, and a part of fuel oil flows out and return to fuel tank 1 from overfall, so as to have adjusted the pressure of common rail pipe intermediate fuel oil
Power, and then the fuel pressure for flowing into fuel injector is also have adjusted from restriction.
In further embodiment, spill port 72 is additionally provided with fuel injector, spill port 72 is connected with fuel tank inlet 11.
Into the fuel oil of fuel injector, a part sprays into combustor by atomizer, meanwhile, from the pin of fuel injector during oil spout
The targeting part of valve gush and the gap of the control sleeve from fuel injector and plunger at leak out unnecessary fuel oil, can pass through back
Oilhole is back to fuel tank 1, re-uses.
In further embodiment, high-pressure pump is additionally provided with relief valve 54 and second outlet 53, relief valve 54 and fine filter
Outlet 422 connects, and second outlet 53 is connected with fuel tank inlet 11.
Due to oil supply system injection pressure it is very high, typically all in more than 130MPa, thus work when oil temperature will be higher,
Light-duty Vehicle can typically reach 80 DEG C, and heavy goods vehicles reach as high as 125 DEG C.High temperature not only can accelerated wear test, be also easy to produce Colophonium,
The materials such as tar, deteriorate oil product.Therefore, during pressurizeing to fuel oil, a part of fuel oil is by high-pressure pump to high-pressure pump
In relief valve enter, and flow out from the second outlet of high-pressure pump, on the one hand play a part of to cool, on the other hand play
The effect of stable oil pressure.The fuel oil of outflow returns fuel tank 1 by fuel tank inlet 11 again, re-uses.
In further embodiment, above-mentioned control device 9 includes sensor 91, controller 92 and executor 93；It is above-mentioned
Sensor 91 is connected with controller 92, for detecting common rail pipe in fuel pressure；Controller noted above 92 is connected with executor 93,
Instructed according to the data genaration that sensor 91 is detected；Instruction adding to high-pressure pump 5 of the above-mentioned executor 93 according to controller 92
Pressure pressure is adjusted accordingly.
In practice, sensor can be attached on common rail pipe, and executor can pressurize in high-pressure pump and be used
Servomotor etc..Fuel pressure in common rail pipe is detected by sensor, after controller is calculated, then by executor to height
The moulding pressure of press pump is adjusted, and so as to be monitored to the fuel pressure of common rail pipe and feedback regulation, and then have adjusted combustion
Burn the fuel delivery and supply time of room.Further, it is also possible to the size of the rotating speed, distributive value according to electromotor, in control device
Best instruction is set, so as to preferably carry out feedback control, and can be according to the different timely adjustments of electromotor.
The high-pressure pump 5 and oil transfer pump 3 of most of common rail systems becomes one, so the cleaner of its configuration is negative
Pressure work, therefore, further, handlance is set on oil water separator 2 or fine cleaner 41, it is more convenient aerofluxuss.
Further, heater and/or chiller are additionally provided with oil water separator 2 or fine cleaner 41.Ambient temperature
Height will also directly affect the normal work of oil supply system, so according to the difference using region, it may be necessary in filtering
Install oil temperature heating or cooling device on device additional.For example, for temperature automatically controlled plus hot charging in temperature lower ground area, can be configured
Put.
