Embodiment
With reference to Fig. 1 and Fig. 4, the form with diesel engine 5 among the figure illustrates an internal-combustion engine, and this diesel engine 5 has connected electronic control unit or controller 10, is used to control the operation of motor 5 and carries out various data processing functions.Controller 10 is operably connected to variable capacity oil pump 15 and controls its output, and this variable capacity oil pump 15 is set for from oil vessel or sump 6 and passes through oil cooler 7 and main flow or full flow filter 8 to motor 5 pump oil.Oil circulates in a usual manner through motor 5, gets back to sump 6 then.
This full flow filter 8 is designed to catch fragment big in the oil and does not produce the excessive back pressure or the pressure loss, so it has coarse relatively filter medium, so that it catches particle size greater than about 15 microns fragment.Therefore, carbon black was dispersed in conventional operation condition in the oil with particulate form under, full flow filter 8 was too coarse and can not catch carbon black granules in the oil, and the carbon black granules in these oil needs to catch the filter of 2 micron particles.
In order from oil, to remove carbon black granules, bypass strainer 16 is connected to working connection by control valve 17.Control valve 17 is controlled by controller 10, when needs are removed carbon black from oil, allows oil to flow through from bypass strainer 16.
In the present embodiment, bypass strainer is a centrifugal filter, but it can be seen, also can adopt the filter of other type.
Controller 10 is provided for receiving the input from many sensors, and these sensors comprise motor operation conditions sensor 11, oily gentle fuel level sensor 12, the historical sensor 13 of maintenance and filter sensors 14.
Motor operation conditions sensor 11 is not a single-sensor, but two sensors that separate, be engine speed sensor (not shown) and engine load sensor (not shown), they provide the speed of expression motor 5 and the signal of load to controller 10 respectively.These signal controlled devices 10 are used for driving carbon black arteries and veins spectrogram (soot map), to estimate the carbon black that deposits in the oil.That is to say that carbon black arteries and veins spectrogram comprises the relation between engine speed and load and the deposition of soot.The technology of carbon black content has more detailed description in the estimation oil in U.S. Patent application 2003/0051696.
Oil gentle fuel level sensor 12 provide with sump 6 in oil temperature and oil the relevant data of oil level.Whether these information controlled devices 10 be used for determining the temperature of oil and having oil to be added to sump 6, and if added oil, then determine the oil mass that adds.
The historical sensor 13 of working provides the information with the replacing time correlation of replacing time of oil and primary flow path filter 8, bypass strainer 16.This information downloads to controller 10 from the diagnostic tool based on computer that car repairing depot is used for maintaining motor 5, but what can find out is also to adopt alternate manner that this information is provided.
The rotating speed of the centrifugal bypass strainer 16 of filter sensors 14 monitoring, by future autobiography sensor 14 the rate transition of removing carbon black each second be actual carbon black quality, can obtain the estimator of the carbon black from oil, removed from this filter 16.A kind of technology that is used to estimate the carbon black of being removed by centrifugal filter 16 is disclosed in U.S. Patent application 2003/0078152.
If the filter that adopts other type as bypass strainer, then will adopt different technology to estimate the carbon black quality of removal.
The operation of this system will be hereinafter with reference to the method that is comprised in the controller, adopts the term of simplifying to illustrate in greater detail.
The carbon black that is produced and deposited in oil by motor 5 of estimation is that the input of adopting the carbon black arteries and veins spectrogram of storing in the storage of controller 10 and being received from motor operation conditions sensor 11 is calculated.The carbon black of being removed from oil by centrifugal bypass strainer 16 is to adopt from the input of filter sensors 14 and calculated in filter carbon black calculator.These two numerals are used to estimate the carbon black of staying in the oil subsequently.Then, adopt the data from historical sensor 13 of maintenance and oily gentle fuel level sensor 12, this measuring and calculating is become accurately, the gentle fuel level sensor 12 of wherein said oil is used to illustrate the oil mass that is added to motor or oily replacing.This provides the estimation to carbon black concentration in the current oil.
Controller 10 foundations are determined carbon black concentration in the oil, are further operationally carried out several other functions.
If concentration is higher than first preset limit, then controller 10 is operationally opened valve 17, flows through centrifugal filter 16 to allow oil, and still, if the concentration of carbon black is lower than this limit in the oil, then valve 17 keeps closing, and does not therefore have oil to flow through centrifugal filter 16.This is favourable, because have only when needing really to remove carbon black from oil, just allows to use bypass strainer.This first preset limit is set at the carbon black that is lower than in the oil motor 5 is produced the level of harm.It is that the energy use amount is low that this selectivity is used the advantage of bypass strainer, because no matter adopt the filter of which kind of type to remove carbon black from oil, energy will be used for making oil to flow through the filter that can remove little carbon black granules from oil.
Another advantage of Fig. 1 and system shown in Figure 4 is to have adopted variable rear pump 15, and it is controlled by controller 10, so the output of pump is not directly related with the rotating speed of motor 5.This makes pump 15 provides whenever can both being activated of required oily flow velocity at needs.Therefore, even engine idle also can be provided with pump 15 so that higher relatively pressure to be provided, such as 5 crust (500kPa), thereby, regardless of the running speed of motor 5, can both guarantee effectively to remove carbon black by centrifugal filter 16.
If the concentration of carbon black surpasses maximum tolerance limit in the oil, then controller 10 operationally sends the warning that the expression oil require is changed to the operator of motor 5.In the present embodiment, this still also can realize by other vision and audible means by making tutorial light 21 shinny realizations of changing oil.The mass percent that typical Cmax is a carbon black in the oil is 3%.It can be seen that this also can represent with the quality gram number of carbon black in every liter of oil.
Controller 10 also operationally calculates the total amount of the carbon black of being removed by centrifugal filter 16 from oil.This is by keeping the carbon black storage calculator of tracking continuously to finish to being removed carbon black, and wherein removed carbon black equals to be stored in the amount of carbon blacks in the centrifugal filter 16.Amount of carbon blacks in being stored in centrifugal filter 16 surpasses the suitable preset limit of maximum safety of the carbon black that can store with centrifugal filter 16, and when this limit was exceeded, controller operationally gave a warning to the operator of motor 5.In this case, this changes filter tutorial light 22 shinny realizations by making, but also can realize by other vision and audible means.
With reference to Fig. 2 and Fig. 3, show the method that is used to carry out aforementioned functional in the controller 10 that is stored in.
Particularly with reference to Fig. 2, this method is from the step 100 corresponding to engine running input (for example " connection ").
In step 110, utilize carbon black arteries and veins spectrogram and the engine speed and the load value that are received from motor operation conditions sensor 11, calculate the amount (S that produces and be sent to the carbon black in the oil by motor 5
PRODUCED).
In step 120, the rotating speed of the centrifugal filter 16 that detects based on sensor 14 calculates the amount (S of the carbon black of being removed by centrifugal filter 16 from oil
REMOVED).
In step 130,, utilize following equation to estimate the concentration of carbon black in the oil based on the generation that calculates and the value of removal:
S
C=(S
PRODUCED-S
REMOVED)/O
VGrams per liter
Wherein, S
CBe the content of carbon black in the oil, O
VIt is the volume of oil in the motor 5.
In step 140, adopt a kind of in two kinds of methods to make this estimation more accurate, showing that oil were replaced if maintain historical sensor 13, serves as that zero general knowledge is that calculate on the basis with carbon black concentration in the new oil-containing value that is received from the historical sensor 13 of maintenance and the fresh oil then.In other words, as long as relate to the calculating of carbon black concentration in the oil, then new oiling will make this system reset.
Show that oil has been added in the motor 5 if maintain historical sensor 13, then controller 10 will serve as that the oil mass value is upgraded on the basis with the oil that newly adds, and the corresponding oily correction calculation that newly adds.This is because do not have carbon black content in the oil that newly adds, in the therefore new oil carbon black concentration will be in the original oil in carbon black concentration and the fresh oil carbon black concentration be zero combining.
For example, suppose that the carbon black concentration in the original oil is the X grams per liter, 4 liters of oil were arranged in the motor originally, newly added 1 liter of oil, the S after then upgrading
CFor:
S
C=(4*X+1*0)/(4+1)=the 0.8X grams per liter
4 liters of numerical value obtain from the gentle fuel level sensor 12 of oil, and when the user that the gentle fuel level sensor 12 of this oil also is used for determining motor 5 refuels and when oil is used to motor 5.The gentle fuel level sensor 12 of oil also is used for providing and the relevant information of motor 5 oil masses variation, and this information can be derived from the oil level the sump 6.This information is used for making the calculating of oil carbon black more accurate, but in this case, precision occurs in the initial calculation of step 130 about carbon black calculating in the oil, in step 130, if oil level descends, serves as the volumetric values (O of basis to oil with the oil level that records then
V) proofread and correct, perhaps in step 140, if oil level increases, expression has oil to add, and then handles in a manner described.In this mode, carbon black concentration is that calculate on the basis with the actual oil mass of the most accurate motor 5 rather than with the theoretical value always in the oil.
Following step is to determine whether to remove carbon black to prevent the infringement to motor 5 from oil.This is the carbon black content S by calculating
CMotor 5 is produced the preset limit S that deceives concentration of carbon in the oil that slightly damages or can not produce infringement with known meeting
ClimitCompare and draw.If carbon black concentration is lower than this limit in the oil, then do not need from lubricant oil, to remove carbon black, this method turns back to step 110.
As can be seen, owing to can obtain the temperature and the volume of oil from the gentle fuel level sensor 12 of oil, so can calculate the quality percentage composition of carbon black in the oil.
Yet,, need from oil, to remove carbon black if carbon black concentration is greater than preset limit in the oil, this method continues to carry out step 160, and in step 160, bypass strainer 16 is started, pump 15 runnings make oil cross bypass strainer 16 with suitable pressure flow, to remove carbon black from bypass strainer 16.Filter process carries out one period scheduled time continuously, is enough to remove enough carbon blacks from oil, and it can not had a negative impact to the serviceability of motor 5.As can be seen, can determine how long bypass strainer 16 needs operation with multiple technologies.
After filtration is finished, detect carbon black concentration in the oil again, with the second high level S
CMAXContrast.S
CMAXBeing to produce amount of carbon blacks in the oil that damages to motor 5, is the higher concentration of preset limit that adopts than in the step 150.If carbon black concentration S in the oil
CSurpass S
CMAX, then this method advances to the step 180 of tutorial light 21 startings of changing oil, otherwise, if carbon black concentration S in the oil
CBe lower than S
CMAX, then this method turns back to step 110.In fact, 21 meetings of tutorial light of changing oil just can be shinny owing to being full of carbon black in the bypass strainer 16 or quitting work for some reason, otherwise bypass strainer 16 will guarantee that carbon black concentration is lower than this greatest limit in the oil.
This step will continue in the running of motor 5, and the data when motor cuts off are controlled device 10 storages, as resetting when motor 5 and the initial data of this method when restarting.Whenever this guarantees that carbon black concentration can both keep accurate calculating in the oil.As can be seen, this method can be in the operation process of motor 5 operation continuously, perhaps be merely able to when motor 5 startings operation once, perhaps can be provided in one section special time of motor operation operation or with other required frequency operation.
As can be seen, this method can also with the deposition rate of carbon black in bypass strainer 16 with make comparisons based on the expectation deposition rate of engine load and speed, determine whether unusual high of deposition rate or than desired height.There is fault in this system that can show motor 5 improper runnings or calculating deposition of soot speed, and this method all is useful diagnostic tool in two kinds of situations, and this method also can be used for indicating suggestion that system is checked to the user.
Referring now to Fig. 3, shown is to calculate the program that is stored in the carbon black in the bypass strainer 16.Step 100 is corresponding to the step 100 among Fig. 2, and in fact this program will combine with the program shown in Fig. 2 and Fig. 3.In step 310, estimation is stored in the carbon black (S in the filter
S).Amount that is removed carbon black that this employing filter sensors 14 provides is finished, and should measure by comprehensive or total then, is stored in the data of the total amount of the carbon black in the bypass strainer 16 so that correspondence to be provided.As can be seen, these data are an estimated value because only provide the tachometer value of filter from the signal of sensor 14, this value and the actual relation that is removed between the carbon black be not determine but estimation.In addition, under instantaneous operating condition, for example when centrifugal filter 16 began to rotate at first, some carbon blacks can spill and get back in the oil from bypass strainer 16.But this estimation has been quite accurate for for when filter 16 is filled with and needs and changes or the guidance that is provided is provided.
In step 320, the estimator (S of the carbon black of storage
S) with the maximum magnitude (S of the carbon black that stores
SMAX) make comparisons, and if the estimator (S of the carbon black that stores
S) above maximum flow (S
SMAX), then this program proceeds to and changes the shinny step 330 of filter tutorial light 22, otherwise this program is returned to step 310, in step 310, will carry out new estimation again.As long as based on the information that is received from the historical sensor 13 of maintenance new bypass strainer 16 has been installed, this calculating will be initialised or reset to zero.
Therefore generally speaking, the present invention will make the operating life maximization of oil, with allow big as far as possible maintenance shop every.It has reduced to cause the possibility of motor infringement owing to oil descends.It for the user has reduced operating cost, thereby has reduced cost of upkeep by reducing required maintenance number of times.
Second advantage be, the changeable flow oil pump only when needs filter oil, just provides extra oil to be used to drive centrifugal filter, and this has improved fuel consume.
The 3rd advantage is that the accumulated amount of carbon black can be compared with predetermined value in the oil, and can detect the excessive generation of carbon black, thereby reduces required maintenance inspection.
Those skilled in the art as can be seen, the present invention describes with the way of example according to specific embodiment of the present invention, but as can be seen, the present invention is not limited to this, within the scope of the present invention, can carry out various changes and modifications to described embodiment.For example,, be not limited to this although the present invention describes according to diesel engine, it can be used for any carbon black be transferred to coil neutralization need prolong maintenance shop every motor.Similar, although the present invention is according to using single controller to describe, as can be seen, controller can be several computing devices that are coupled to each other.
Can further find out, can adopt conventional centrifugal filter, rather than use intelligent centrifugal filter to estimate the carbon black of from oil, removing or be stored in carbon black in the filter with velocity transducer, set up a lookup table by test job in advance, the filter operation time period and the other factors that utilize and carried out, for example, relevant information such as engine speed, load, oil pressure and temperature, the carbon black that can obtain removing from this lookup table and the carbon black of storage.
