According to the invention an optimization of the lubrication and of the acid neutralization and thus high operational reliability and economic efficiency can be achieved in that at least one lubricant having a neutralization capability that does not exceed the neutralization requirement in any possible use case and at least one lubricant having an neutralization capability that is not less than the neutralization requirement in any possible use case are used and that the lubricants used are individually fed to the cylinder interior in metered amounts and are mixed in the cylinder interior.
Description
Technical field
The present invention relates to the method and apparatus carrying out cylinder lubrication in a kind of piston internal-combustion engine of the fuel for generating acid in burning, wherein use and there is the multiple greasing substance of different neutralising capacity, each greasing substance with respectively to required in the ratio relevant with lubrication needs with demand mutually admix.
Background technique
Use term " cylinder " and " cylinder liner " below as an alternative; and be interpreted as; the parts that both ordinary representation is such; namely it has at least one cylinder-bore of the piston for moving up and down; to limit the volume of the firing chamber arranged mutually, this is encompassed in the protection domain of claim equally.The specific types of lubrication of the working surface of cylinder or cylinder shell is mainly present in big-block engine, and described big-block engine is usually cross-head type and may be used for the possible lubrication environment of the lubrication environment of cylinder/piston area with usual more key types (such as lubricating the bearing on bent axle) to keep separating.The cylinder of motor is usually arranged with parallel vertical cylinder-bore axis in rows.But it being understood that the layout of each cylinder-bore axis of motor and each relative positioning of possible multiple cylinder-bore axises are included equally.
Multiple object is realized by carrying out lubrication to the slip surface between the cylinder liner and the piston moved of piston reciprocating internal combustion engine wherein.Lubricating film should be formed, to avoid the slip surface based on both sides to cause the direct contact of material on the one hand by oiling agent.Refer to the direct contact avoiding metal to metal under normal circumstances this its, but this is also important in other combination of materials.On the other hand oiling agent should avoid the acid attack to slip surface, its mode for: the acid product when burning, especially produced when the heavy fuel oil burning with high sulfur content is neutralized.The neutralising capacity of oiling agent represents with BN unit (mgKOH/g) usually.
(DE10112691A) propose, for cylinder lubrication use, there is the oiling agent of particular B N number and improve according to the Sulpher content of used fuel or reduce the amount flowing to the oiling agent of cylinder.But it is set in very high or low-down Sulpher content.The increase of the oiling agent carried exceeds specific amount and oiling agent is throttled to the damage that all can cause motor lower than specific amount.According to the present invention, oiling agent is excessive can cause so-called polishing.Its consequence be oiling agent not to be attached on surface to be lubricated and and then cause material based on the slip surface of both sides cause the direct contact improved of wearing and tearing.This such as occurs in based on the device of DE10112691A1, because be provided with the direct contact of metal to metal at this place.But allow all acid not to be neutralized by limiting the amount of carrying.Be reduced on the other hand and oiling agent can be caused to lack and correspondingly cause tearing and then causing and identical shortcoming of lubricating film above lower than specific minimum value.But, there is too much neutralising capacity when limiting the amount of carrying and being only reduced to specific minimum value and do not wasted by using.Because neutralising capacity is based on adding relatively costly additive, produce the Economy of difference at this.
(JPH03-1941109, open on August 23rd, 1991) also proposed be, kept having the lubricant oil of different neutralising capacity and mixed with the mixed proportion relevant to the Sulpher content of fuel by each lubricant oil and mixture is flowed to cylinder, wherein carried amount is constant.Equally, (JP1041619A, open on February 13rd, 1989) proposes, and the Sulpher content of based on fuel is that specific lubricant oil adds the additive improving neutralising capacity more or less.At this, the amount flowing to cylinder is also constant.In both cases, for cylinder carries the mixture made.Mixing is carried out in advance.But this causes too high dead time when expecting change mixed proportion.Because only change mixed proportion in both cases, but do not change the total amount flowing to cylinder, this also can cause lubricant oil excessive or lubricant oil disappearance in both cases.
Summary of the invention
In view of this, therefore the object of the invention is, improve by mechanism that is simple and low cost the method and apparatus starting described type, make the optimization that can realize lubrication property and neutralising capacity for all service condition imagined and then the high safety in operation that can realize when the Economy of maximum possible.
According to the present invention, described object realizes as follows: use have do not exceed under any considered service condition required in and at least one greasing substance of neutralising capacity of demand, and use have when any considered be all not less than required in and at least one greasing substance of neutralising capacity of demand, and the greasing substance used flows to cylinder interior in the mode of measuring fixed amount, preferably flows to cylinder inside independently, admix at this place.
The shortcoming of known arrangement is avoided completely by described measure.Extreme usage ratio is utilized to mate extreme greasing substance up and down to guarantee in acid yield according to the present invention: oiling agent always can not occur excessive and oiling agent disappearance always can not occur, and however still produced acid fully can be neutralized all the time.Because the blending of two kinds of greasing substances is only carried out in cylinder, therefore also realize very short dead time when the mixed proportion desired by changing in an advantageous manner.Independently measure the lubrication coupling of the local difference requirement that also can realize in an advantageous manner in cylinder.
The favourable design proposal of primary measure provides in the dependent claims with the improved form meeting object.
Therefore, it is possible to prove advantageously, except above-mentioned extreme greasing substance, also can also will have at least another kind of substance use of other auxiliary property to cylinder inside.Even if this can realize the favourable adjustment to working surface when exceeding lubrication.Therefore by this way such as can burning low-sulfur or the fuel of not sulfur-bearing time to be suppressed the danger on too level and smooth surface by input acid to a certain degree.Another kind of material also can be the lubricant oil in the consideration BN interval of basic different viscosities.Can additionally realize thus the setting of neutralising capacity and the setting to required practical viscosity.
Blending desired by the material carried in cylinder can realize in a different manner.The simple especially possibility of one can be, the material used is carried like this, makes it due to superposed on one another when Action of Gravity Field flows downward and wetting.
Another kind of possibility can be, the material used flows to cylinder like this, makes to impact realization by means of at least one mechanical mechanism inswept at transfer position place and/or Pneumatic pressure and smears.So-called mechanical mechanism also can be the sliding element that be arranged on piston side, such as piston ring or the scraper ring inswept at transfer position place, and described piston ring or scraper ring cause the mixing of carried material and flatten whole in each upper and lower stroke of the piston arranged mutually.
Another kind of possibility can be, the material used is carried like this, makes to produce the spraying beam crossing at transfer position place and/or atomizer cone.Certainly the multiple of type or whole possibility is mentioned above also can using.
Can propose according to another favourable design proposal, often kind of material is carried via the transfer position of self.This can together with independent measure realization especially simply the mating the requirement of individual cases to different material.
The measure that another kind meets object can be, the conveying of different material is controlled individually for each cylinder or often organize for associated cylinder.This causes the optimization of the cylinder lubrication of whole motor in an advantageous manner, such as, when one or more cylinders of motor are with the power stage reduced operation or when even periodically dallying.
A kind of simple constructional measures can be, be provided with in cylinder wall be distributed in circumferentially, arrange to the lubricating nozzle of used material, wherein arrange and go up at various height to the distribution of the lubricating nozzle of different material.This measure above mentioned blending and/or cause mixing by the element inswept along cylinder bearing face because Action of Gravity Field causes.This advantageously can be provided with at least two rows self be stacked setting, arrange to different greasing substance, the lubricating nozzle that circumferentially extends at cylinder.
Another kind of favourable measure can be, lubricating nozzle is to arrange according to the distribution patterns being matched with local particularity and/or can activate.Therefore, it is possible to consider special local circumstance simply especially, as the side direction piston press (such as horizontal air cylinder axis) of reinforcement and/or the acid yield etc. of local strengthening.
Can propose according to another favourable design proposal, lubricating nozzle is configured to have at least two at least in part and arranges to the multiinjector of the entrance of different material and arrange to the nozzle opening of described entrance.In an advantageous manner different greasing substances or other component can be flowed to the cylinder arranged mutually simultaneously by this lubricating nozzle, this not only contributes to the greasing substance blending desired by formation, and can realize carrying other helper component simultaneously.Advantageously, nozzle opening can be orientated at least in part, makes to pass through beam that carried different material formed or atomizer cone encounters one another or intersect.Usually available calibrating nozzle can be selected for expection object.
By the different greasing substance of independent measure with if desired, the another kind of possibility that other component flows to cylinder by common lubricating nozzle can be able to be, is formed by a series of portion's section be made up of the used different material in greasing substance form and other component arranging the fluid column that produces in the supply pipeline of lubricating nozzle, the volume of described portion section is determined with demand and lubrication needs and/or other demand according in existing.The different portions section that this one after the other produces fluid column is at each lubricating place, wherein can realize the change to a certain degree about the fluid type produced at different lubricating place place simultaneously by the different length of supply pipeline and/or diameter of guiding different lubricating place into, this can cause mixing intensive especially.But it is also contemplated that pass through the suitable configurations of various flows scapus, even if also this result can be realized in same supply pipeline that is that grow and/or same volume.

Embodiment
Main application fields of the present invention is the large combustion engines with crosshead, especially has uniflow scavenged two-stroke large diesel engine, and it drives with heavy fuel oil usually.Heavy fuel oil can containing relatively many sulphur, and this can cause the formation of sulfuric acid etc. when burning.Slip surface that is that acid can corrode piston and/or cylinder liner and therefore must be neutralized to avoid this erosion.
There is the structure of uniflow scavenged big-block engine type (as two-stroke large diesel engine) and the mode of action itself known and therefore only just the understanding content wanted required for the present invention is set forth below.
Fig. 1 illustrates the cylinder 1 of this motor.Be typically provided with the multiple such cylinder 1 preferably set in a row.In each cylinder 1, be provided with piston that arrange mutually, that be not shown specifically at this, described piston forms the moveable gauge to firing chamber 2.The slip surface of cylinder 1 and the piston moved wherein lubricated.For this reason, in cylinder wall, be provided with lubricating nozzle 3 that is mounted, that can load with greasing substance, described lubricating nozzle is only schematically indicated in FIG.Lubricating nozzle 3 can be the nozzle being provided with safety check, opening under stress.Otherwise lubricating nozzle can be the lubricating nozzle of the known type being applicable to described object usually.The distribution of the greasing substance of being discharged by lubricating nozzle 3 on the circumference and height of cylinder inside is usually by mechanism's (as scraper ring and/or piston ring) of inswept lubricating nozzle 3 or by realizations such as the compression shocks by exhausting air or the generation of loading air.
Two objects are realized under normal circumstances by lubrication.The lubricating film for carrying should be formed on the one hand on the slip surface in opposite directions of cylinder 1 and piston, to prevent from directly contacting to the material of slip surface in opposite directions with arranging, such as, when by the direct contact preventing metal to metal when the slip surface that metal is formed.In addition the acid product produced in answering and when burning.Form sulfuric acid more or less according to the S content (Sulpher content) of used fuel, and therefore need the neutralising capacity more or less of oiling agent.The neutralising capacity of oiling agent realizes by adding suitable additive usually.But this is very expensive, thus should use as far as possible frugally.On the other hand, too much and very few oiling agent is all harmful.Oiling agent is excessive can be caused so-called slip surface polishing and then cause it to the reduction of the affinity of greasing substance, and greasing substance disappearance can cause tearing of lubricating film.Both less desirable.
In order to both in cost also lubricating effect and in and in realize optimizing, use to have in difference and the multiple greasing substance of characteristic to realize cylinder lubrication.At least one greasing substance is provided with at this, its neutralising capacity do not exceed in any contemplated service condition required in and requirement, and be provided with at least another kind of greasing substance, its neutralising capacity be not less than under any contemplated service condition required in and demand.The greasing substance used flows to cylinder inside with certain gauge amount independently, then mixes there, namely admixes.Due to this measure, therefore never occur greasing substance disappearance and greasing substance excessive.Because carry out independent measure with demand and greasing substance demand in required, so provide enough neutralising capacities all the time to neutralize the acid of all acquisitions, but more neutralising capacity can not be provided, avoid thus using the additive promoting neutralising capacity.
In based on the example of Fig. 1, use two kinds of greasing substances A, B, wherein often kind of greasing substance all has one of above-mentioned extreme nature.The hopper 4 or 5 arranging self for often kind of greasing substance A, B is as reservoir vessel.Be arranged in cylinder wall, the lubricating nozzle 3 be distributed in circumferentially partly arrange to wherein a kind of greasing substance A and partly arrange to another kind of greasing substance B.Therefore, often kind of greasing substance A, B are equipped with the lubricating nozzle 3 of self.Certainly, also can use more than two kinds of greasing substances.But must be at least two kinds of greasing substances with extreme nature above-mentioned all the time at this.
The lubricating nozzle 3 be arranged in cylinder wall is partly arranged to be gone up at various height.In shown example, be provided with the lubricating nozzle 3 that two rows are stacked setting up and down, wherein, upper row should arrange to greasing substance A and lower row should arrange to greasing substance B.The pattern of certain lubricating nozzle also can be different from be stacked up and down setting two row and arrange.The greasing substance of discharging from lubricating nozzle 3 is because gravity is to dirty, the greasing substance B that the greasing substance A wherein flowed out by the lubricating nozzle 3 on top can discharge with the lubricating nozzle 3 from bottom superposes and soaks, and this has realized mixing, namely desired blending.This by relative to cylinder wall motion piston assist, described piston is provided with scraper ring or piston ring, described scraper ring or piston ring inswept on lubricating nozzle 3.Equally, aerodynamic effects can be produced by being impacted by exhausting air and/or loading air applied pressure.
Greasing substance A, B according in each needs with demand and the lubrication needs lubricating nozzle 3 that arranges mutually of metering and therefore flowing to and being incorporated in cylinder 1 via described lubricating nozzle according to quantity independently.Different devices can be used for this reason.
For greasing substance A, according to be provided with pump 6 in example illustrated in fig. 1 and loaded by described pump, the pressure piping 7 that in fact forms common rail, guide each into and arrange to the supply pipeline 8 of the lubricating nozzle 3 of greasing substance A from this pressure piping.Pump 6 is configured to pressure pump at this, there is greasing substance A in its ingress due to Action of Gravity Field.Correspondingly, the hopper 4 arranged mutually is preferably arranged higher than pump 6.Be provided with control valve unit in order to activate or stop using to arrange to the lubricating nozzle 3 of greasing substance A, supply pipeline 8 can be connected with pressure piping 7 by means of described control valve unit and vice versa.In shown example, control valve unit comprises the switch valve 9 in the outlet port being arranged on pressure piping 7.Certainly it is also contemplated that each supply pipeline 8 is equipped with self switch valve, this can realize different opening times and/or cycle time.The opening time of one or more switch valve 9 is determined to arrange the lubricator quality to lubricating nozzle 3 respectively.Correspondingly, this be switch valve 9 form control valve unit as by the pilot line 10 that arranges mutually indicate controlled, described pilot line, from control gear 11s, also will be inquired into below more control gear.According to selected by reality, the demand that produces in the layout of pipeline 7,8 and valve 9, pump 6 such as can have electric storage means, the excess pressure valve regulating pressure or other pressure stability mechanism and the control mechanism (not shown) had this necessity in downstream, as those skilled in the art are usually known.
Another example of greasing substance supplier is shown by greasing substance B in FIG.At the device that this can use a pump or comprise multiple pump.In shown example, be provided with multicell metering pump 12, each room 13 of described multicell metering pump is connected with each lubricating nozzle 3 arranged mutually for greasing substance B via supply pipeline 8 respectively.Certainly the pump of other type can also be imagined.In the upstream of working pump (form in multicell metering pump 12 in shown example), supply pump 14 can be set, described supply pump is configured to suction pump and pressure pump in shown example, and described supply pump is correspondingly connected in suction side and arranges on the hopper 5 of greasing substance B and on the entrance being on the pressure side connected to multicell metering pump 12.Multicell metering pump 12 only can absorb specific lubricator quality in each stroke.Correspondingly, pump 14 also can be equipped with return line 15, excessive conveying capacity is delivered in hopper 5 to feedback via described return line.As an alternative, pump 14 can be self-regulating type, to be independently kept for the pressure of pump 12 with the required flowing of leading to pump 12.The capacity of each room 13 of multicell metering pump 12 is equal in the embodiment illustrated.In each stroke of multicell metering pump 12, the lubricating nozzle 3 arranged mutually is correspondingly loaded with identical lubricator quality.Also can imagine the sizes that are different, that can independently set of each room 13, different demands can be considered by place thus.
The switching frequency that the stroke frequency of pump-unit of that can drive by means of drive unit, such as in multicell metering pump 12 form can be similar to switch valve 9 controls like that, as by arrange to the pilot line 16 of the driver of multicell metering pump 12 indicate, described pilot line is same from control gear 11s in shown example.Control gear 11 according in corresponding and demand and lubrication needs control each the carried amount of greasing substance A and greasing substance B, make to provide enough neutralizers in each case, but more neutralizer is not provided, and make to be lubricated fully, but it is excessive not produce oiling agent simultaneously.Control gear 11 processes corresponding running parameter for this reason, as by least one running parameter entrance 17 indicate.Control gear 11 can be the CCU for whole motor, the greasing substance conveying arranged to each cylinder or each cylinder block is controlled independently, as indicated by additional pilot line 10a or 16a guiding other cylinder in FIG by described CCU.But it is also contemplated that be the control gear that each cylinder or each cylinder block arrange self.
The measuring apparatus with switch valve 9 or metering pump 12 described in FIG is only exemplary.The quantity of the greasing substance used also is exemplary.Certainly also as already mentioned, use more than two kinds of greasing substances or other material with desired characteristic, but wherein at least two kinds of greasing substances can should have above mentioned extreme nature.Certainly same it is also contemplated that in order to measure all greasing substances, identical measuring apparatus is arranged with the form of switch valve or metering pump.
Exemplarily be provided with such as two rows in FIG and be stacked the lubricating nozzle 3 of setting up and down.But it is also contemplated that in larger district, be provided with more row's lubricating nozzles.This example is based on Fig. 2.At this, reference character 18 is marked at district inswept by the upside of piston 19 in cylinder 1.In the region in district 18, be provided with multiple lubricating nozzle 3, each lubricating nozzle can arrange according to specific distribution patterns and/or activate.Can be provided with at this lubricating nozzle 3 that many rows are stacked setting up and down, wherein row's lubricating nozzle can be supplied to only a kind of greasing substance type or multiple greasing substance type, respectively as shown by L and N in fig. 2.This can by correspondingly distribute and/or activate arrange to consider the lubrication needs different by place to the lubricating nozzle 3 of each greasing substance or in and demand.This is also applicable to structure situation, the side direction piston press such as strengthened or the acid formed by place reinforcement due to the special position of fuel injection.
Obviously it is also contemplated that the measure that the measure combination shown in fig. 2 is mentioned by Fig. 1 is combined in the change in the control time of the control valve of supply pipeline 8 and/or in the change of the size of the room 13 of multicell metering pump 12 in arranging.Activate selected lubricating nozzle 3 can realize as follows simply from larger lubricating nozzle regioselectivity: only selected lubricating nozzle 3 supplies the greasing substance etc. be allowed a choice.
Lubricating nozzle 3 can be that open under stress, simple, to be provided with safety check pressure nozzle.Certainly also can imagine and be configured to spray nozzle and/or jet nozzles.Safety check also can be arranged on other place guided in the supply pipeline 8 of lubricating nozzle 3, or also can abandon safety check, be like this when pump/valve system (13,9) has the proper capacity that can bear the pressure-loaded sent from cylinder volume.It is also envisaged that lubricating nozzle 3 a kind of greasing substance or multiple greasing substance load.This can with multiple greasing substance load and the lubricating nozzle being correspondingly configured to multiinjector 20 based on Fig. 3.Multiinjector 20 have multiple different greasing substances at this being two kinds of greasing substance A and B form, in shown example i.e. two entrances 21,22.Equally, multiinjector 20 have multiple arranging to different greasing substance, in shown example namely two arrange to the fog head 23,24 of greasing substance A and B.Described fog head can be set as, discharged spraying beam 25,26 is encountered one another, therefore realizes or contribute to the desired blending of greasing substance A and B.In shown example, fog head 23,24 produces the spraying beam encountered one another.But it is also contemplated that produce the atomizer cone that intersects each other and realize by this way or contribute to desired blending.
Similarly, multiinjector 20 is based on the example according to Fig. 4.At this, fog head is set as, makes described fog head by encountering one another in region between described multiinjector of the beam 25,26 formed by different greasing substance A, B of multiinjector 20 adjacent one another are and therefore causing or contribute to desired blending.
Fig. 5 illustrates that described material is greasing substance and/or other material with desired characteristic for causing the another kind of possibility of the desired blending of many kinds of substance (in this case A, B, C) by only lubricating nozzle respectively.Be provided with again multiple lubricating nozzle 3 be arranged in cylinder wall at this, each lubricating nozzle can be arranged up and down stackedly, abreast or according to the distribution patterns preset.Each lubricating nozzle 3 is equipped with supply pipeline 27.Each nozzle 3 is loaded by all materials used at this, is namely loaded by substance A, B, C in this example.For this reason, liquid column that produce in each supply pipeline 27, that be in lubricating nozzle 3 place arranged mutually is configured to the sequence of the post portion section 28 be made up of different material, and described post portion section is in Figure 5 respectively with the substance A arranged mutually or B or C mark.
The length of the post portion section 28 arranged with each substance A, B, C phase depends on corresponding demand, especially depend on corresponding lubrication needs and/or in and demand.Be provided with for this reason for multiple, in shown example for the common metering pump 29 of all supply pipelines 27, described metering pump can be loaded by the substance A being used, B, C and correspondingly have to use substance A, B, C the corresponding quantity of quantity respectively with the entrance 30 that arranges mutually of substance A, one of B, C of using, described entrance has the supply pump 31 arranged mutually respectively.In addition, metering pump 29 also has the outlet 32 of the quantity corresponding to the quantity of connected supply pipeline 27.The function of metering pump 29 is, each stroke activates another entrance 30 respectively, forms the above mentioned sequence being equipped with the post portion section 28 of different material A, B, C thus.
The volume of each post portion section 28, the i.e. length of each post portion section 28 when the diameter of supply pipeline 27 is identical, as directly perceived in Fig. 5 visible can be different, this different running length by metering pump 29 or the change by the cumulative unit dosage summation of metering pump realize.Metering pump 29 can construct at this similarly and control, as referenced according to the multicell metering pump 12 in the example of Fig. 1.Difference is only, the entrance 30 that be provided with more, can activate as an alternative.
In each stroke of metering pump 29, the oiling agent volume that lubricating nozzle 3 is discharged and the oiling agent volume be transported to from metering pump 29 supply pipeline 27 are as many.As long as all supply pipelines 27 are identical, namely have identical capacity, so on the lubricating nozzle 3 arranged mutually, there is identical material type respectively, then this is also applicable to the medium from lubricating nozzle 3 outflow.At this, according to the length of the length of portion's section 28 and the relevant stroke of metering pump 29, it can be the content of each post portion section 28 or all or part of content of multiple post portions section 28.Likely be thus for whole cylinder wall provides the blending of the independent different material introduced fifty-fifty.This still continues in the different length of supply pipeline 27 or when having different-diameter (namely having different capabilities) to strengthen, and makes there is different greasing substances respectively at each lubricating nozzle 3 place and be ejected in each stroke at metering pump 29.Therefore high viscosity is feasible.
In order to ensure extra high Security, at least one element of greasing substance supplier can have the mark 33 such as indicated in the region of hopper 5 in FIG, learns the classification of device according to parameter (as installed date, maintenance, working life etc.) from described mark.Meet object, this mark 33 can be configured to RFID chip, and described RFID chip can read in a contactless manner, and wherein this device meets destination and is chosen as, and makes this be feasible from outside.It is contemplated that be provided with for whole motor the mark that common mark 33 or each cylinder or each cylinder block are equipped with self.
The present invention is not limited to shown and described example.
Therefore, can also by one or more other substance use to cylinder inside except greasing substance, it has other valuable characteristic.Such as, at least one the 3rd liquid is also carried except two kinds of liquid forming extreme greasing substance, in fact described 3rd liquid form the medicine for a type of motor and can flow to such position of cylinder wall, and described position such as finds the danger starting so-called corrosion.Then special oiling agent or other auxiliary liquid can be guided to relevant position by the nozzle of selected quantity according to desired conveying pattern (that is with desired local distribution) in this case.Can advantageously when producing so-called polishing danger or causing polishing, the other liquid flowing to slip surface is acid, and realize etching to a certain degree thus, this causes the roughening of slip surface and then improves the attachment of oiling agent.Similarly it is contemplated that other liquid or liquid composition are only introduced every now and then at run duration by means of one or some nozzles.
The cylinder oil of calculated excessive use is collected in some big-block engines.Larger or the less share of the cylinder oil used like this can advantageously be delivered in cylinder to feedback again, such as the component C with average quality, or rather, the clean of necessity or filter and check be used for correct calculate the characteristic of corresponding A, B and C metering after.
In addition it is mentioned that; system in the protection domain of claims also can be run with the cylinder lubrication component of self; or rather; when not needing the neutralising capacity etc. added, this can be such as when having situation when in fact running with gas or other sulfurous fuels according to the big-block engine of system of the present invention.In addition may expect in the motor with multiple cylinder: one or more cylinder can dally, and is not namely supplied by fuel.This can be such as expect, to reduce the power that sends or to avoid at sea losing efficacy during critical situation.The three components being only used for lubricating advantageously can be introduced in this case or be directed in cylinder to returning.
