A lubricating system for lubricating a piston traveling surface of a cylinder wall has at least one lubricating oil nozzle disposed in a recess of the cylinder wall for a cylinder to apply lubricating oil onto the piston traveling surface. The lubricating oil is converted into at least one dense lubricating oil jet, and can be added tothe piston traveling surface of the cylinder wall, and the lubricating oil nozzle is designed so that atomization of the lubricating oil jet by the lubricating oil nozzle can be considerably avoided.In addition, a method for lubricating the cylinder wall of the cylinder of the reciprocating internal combustion engine having the lubrication system is proposed.
Description
Technical field
The present invention relates to a kind of be used for reciprocating internal combustion engine, particularly have longitudinally scavenged two-stroke large diesel engine lubricated lubrication system and a kind of use according to the lubricated reciprocating internal combustion engine of lubrication system of the preamble of the independent claims of corresponding generic method.
Background technique
Have longitudinally scavenged two-stroke large diesel engine and serve as the driver element of boats and ships usually, perhaps also can be used in the static state operation, for example be used to drive power large-scale electric generating station, to produce electric energy.In this respect, motor is the suitable time phase of operation under constant operating mode usually, and this has proposed the high request to functional reliability and validity.For this reason, particularly long servo interval, low wearing and tearing and the economy of fuel and work materials is used is the core of operator when selecting machine.Wherein, the piston roadability of so big cylinder diameter slow-running diesel engine is the determinant factor of servo gap length and validity, and also directly influences running cost by the consumption of lubricant oil.Therefore the lubrication problem of the complexity of two-stroke large diesel engine becomes more and more important.
For having longitudinally scavenged two-stroke large diesel engine, piston lubrication is carried out on cylinder wall by lubricating fitting, lubricant oil is applied on the operation surface of cylinder wall by this lubricating fitting, so that the friction minimum between piston and the operation surface makes the surperficial abrasion minimum of operation thus.For example, for modern motor for example for the Sulzer RTA motor, the wearing and tearing on current operation surface after 1000 hours operating time at least less than 0.05mm.The flow of lubrication of such motor approximately is 1.3g/kWh or littler, but it is highly important that for the cost reason, and this flow also should be reduced forr a short time within the bounds of possibility.
The solutions of various lubrication systems about lubricated operation surface are disclosed, both about the specific design of lubricating fitting, again about lubricating method.For example, radially along the circumferential direction be contained in oilhole in the cylinder wall at disclosed lubricating fitting lubricant oil and be applied to operation through on the piston of oilhole by several, and by the piston ring lubricant oil that along the circumferential direction and in axial direction distributes simultaneously.Because lubricant oil is not applied on the big area on operation surface of cylinder wall by this method, but more or less with the point form on the side surface that is applied to piston between the piston ring, so often can not guarantee that lubricant oil is in the lip-deep enough distributions of operation, this will be owing to excessive friction causes the heat load that increases, final result is, the contact area on piston and operation surface is because consequent material breakage and local welding is got up, i.e. stuck piston.
Distribution preferably in order to ensure lubricant oil, promptly guaranteeing has the more uniform lubricant film of one deck on the operation surface, a kind of lubrication system has been proposed in WO 00/28194, wherein lubricant oil under high pressure is ejected in the scavenging usefulness air that is in the combustion space by the atomizer nozzle that is contained in the cylinder wall with being tangential to cylinder wall substantially, and makes lubricant mist change into granule.Therefore lubricant oil after the atomizing is distributed in scavenging subtly with in the air, and the operation surface of the centrifugal force impingement cylinder wall by the moment of momentum born with air by scavenging, so oil particles just is distributed in subtly and moves on the surface.Really, this method is compared with the method for using radially lubricant oil injection, has produced lubricant film more uniformly on the operation surface; Yet an important disadvantages of this method is that quite a few of used lubricant oil burns with air with scavenging or burn in ensuing combustion process.Produce unnecessary high lubrication oil consumption thus, this has very adverse influence to running cost.In addition, also cause special requirement,, therefore the available selection that is used for this lubricated lubricant oil is restricted because not every lubricant oil all is suitable for being atomized subtly to the quality of the lubricant oil that can use.Particularly, cheap lubricant oil, promptly low-quality lubricant oil normally can not resemble and atomizes well the high-quality lubricant oil, so when using such lubricant oil, the validity of this method has been further reduced.
Summary of the invention
Therefore, an object of the present invention is to propose a kind of lubrication system of having improved, this system is used for reciprocating internal combustion engine, particularly has operation surface lubricated of cylinder wall of the cylinder of longitudinally scavenged two-stroke large diesel engine, guaranteed that by this lubrication system oiling agent better distributes on the operation surface of cylinder wall, the amount of oiling agent is compared with known lubrication system and is reduced greatly simultaneously, therefore can realize a kind of more economic work of such reciprocating internal combustion engine.Another object of the present invention is to propose a kind of lip-deep correlation method of operation that oiling agent is applied to cylinder wall by means of lubrication system according to the present invention.
The present invention satisfies the feature that these features at the theme of the purpose aspect device and the technological method are all kinds of independent claims respectively.Dependent claims relates to the particularly advantageous embodiment of the present invention.
According to the present invention, thereby a kind of internal-combustion reciprocating-pisto that is used for has been proposed, the lubricated lubrication system on operation surface of cylinder wall that particularly has the cylinder of longitudinally scavenged two-stroke large diesel engine, piston is arranged along the surperficial to-and-fro motion of operation ground in cylinder, cylinder has the oiling agent nozzle at least one groove that is arranged in cylinder wall, so that oiling agent is applied on the operation surface, it is characterized in that, the oiling agent nozzle has several exhaust ports that is used for the ejection of oiling agent, described exhaust port allows identical or different oiling agent throughput, so arrange and design oiling agent nozzle, thereby oiling agent can be applied on the operation surface of cylinder wall with the oiling agent beam of a plurality of densifications.
Guaranteed by layout and design according to the oiling agent nozzle of lubrication system of the present invention: oiling agent can be applied directly on the operation surface of cylinder wall of cylinder of reciprocating internal combustion engine.Have found that, guaranteed evenly applying and economic use of oiling agent thus simultaneously.
In a preferred embodiment of the invention, this lubrication system comprises several oiling agent nozzles, and these oiling agent nozzles are arranged along the circumference of the cylinder of reciprocating internal combustion engine, for the symmetry properties reason, preferably by the pitch arrangement that equates.Be preferably perpendicular to the cylinder axis that extends along cylinder by this circumference area surrounded at this.In some cases, this also is possible certainly, and promptly the oiling agent nozzle is not to be arranged on such circumference, but is arranged in a different manner on the cylinder wall, for example is arranged in one along on the curved-line thread path of cylinder axis direction extension.It is contemplated that in addition this lubrication system comprises the oiling agent nozzle that several are arranged along several parallel circumferences.For example, the oiling agent nozzle can be arranged in one or more varying level places in the cylinder that are in, promptly for example, the following reversal point of in cylinder, moving near piston and/or near on reversal point and/or on the such circumference between this upper and lower reversal point.Therefore can guarantee that the operation surface all is applied with lubricant oil anywhere ideally.

In the work of this reciprocating internal combustion engine, piston 5 moves between a reversal point OT who illustrates the place, top and a reversal point UT at the illustrated base place in a kind of known mode, thereby the surface 52 of piston 5 is all passed through at least one groove 6 and/or at least one groove 11 of cylinder wall 3 thereon and between the following reversal point during motion, thereby at least one groove 6 of cylinder wall 4 and/or at least one groove 11 are covered by the side surface 53 of piston 5 every now and then.Fluted 6 and/or all groove 11 positions in cylinder wall 3 all link to each other with combustion space 15; And when piston was in reversal point OT position, institute fluted 6 and/or all grooves 11 in the cylinder wall 3 all linked to each other in piston 5 interior space beneath with cylinder 4.
Fig. 2 shows a cylinder 4 by a section according to Fig. 1 A-A along the line, and it comprises an example according to a lubrication system 1 of the present invention, and it has an oiling agent nozzle 7, a measuring unit 13 and a control gear 14.Oiling agent 8 can supply to oiling agent nozzle 7 from measuring unit 13 by means of a supplier 12, and oiling agent 8 is supplied with this measuring device through a supply line 131 by the concentrated area.A preferred independent pipeline is directed to each oiling agent nozzle 7 from measuring unit 13, thereby oiling agent 8 can be according to the different operating parameter of reciprocating internal combustion engine to the supply of each oiling agent nozzle 7, for example speed, load, cylinder temperature or other running parameter and be provided with independently.Oiling agent 8 naturally also can be by irrelevant the carrying out of the running parameter of predetermined scheme and reciprocating internal combustion engine to the supply of oiling agent nozzle 7.Particularly, it is contemplated that also one or more oiling agent nozzles 7 are passed through a common supply line 12 to link to each other with measuring unit 13 under a predetermined working pressure.Preferred emollient nozzle 7 has a valve 72, and for example one with a kind of known way spring-biased valve 72.In this respect, valve 72 can so be set, thereby it can spontaneously be opened under the effect of the working pressure that waits the oiling agent 8 in supply line 12, thereby oiling agent 8 can flow out from supply line 12 and enter oiling agent nozzle 7, and can be fed on the operation surface by the mode of exhaust port with a kind of pulsed.In addition can by one oiling agent nozzle 7 places or in safety check 73 protection supply lines 12 avoid overvoltage in the cylinder side.Preferred so valve design 72, thus it can satisfy its function simultaneously as safety check 73.
Preferably by means of free presetting apparatus 14 controls and adjusting measuring unit 13, and equally with respect to supply line 12 assembling safety check (not shown), thereby amount or the timing of supplying with the oiling agent 8 of each oiling agent nozzle 7 can be according to the different operating parameters of reciprocating internal combustion engine, for example speed, load, cylinder temperature or other running parameter setting.For example, the amount of the amount of oiling agent 8 and/or fuel or other work materials not only can be determined with regularly common, also can determine jointly with the amount of the oiling agent of being supplied with 8.These running parameters can be read by sensor (not shown at this), and supply with the free presetting apparatus 14 that passes through the corresponding control of connection or regulate measuring unit by datawire 141.
Showing oiling agent beam 9 oiling agents in a kind of concise and to the point mode in Fig. 3 is applied on the operation surface 2 as a kind of preferred mode how.Oiling agent nozzle 7 has an exhaust port 71, and this exhaust port is so design, thereby oiling agent 8 is discharged with the oiling agent beam 9 of densification, and promptly oiling agent beam 9 has been avoided greatly by the atomizing of oiling agent nozzle 7.Particularly a kind of scavenging in being in cylinder has been avoided greatly with the atomizing in air and/or the gas.Oiling agent 8 quite directly is applied on the operation surface with the mode of the pulse beam by densification.Preferably groove 6 is designed to the groove of an inclination, thereby the oiling agent beam 9 of discharging from exhaust port 71 advantageously is discharged in the combustion space 15 about moving surface 2 tangent directions along a cardinal principle, thereby oiling agent 8 directly is applied on the zone 91 in the direction that is in oiling agent beam 9 on operation surface 2.Zone 91 for example upwards seemingly up extends to another along the nearest groove 6 of circumference from exhaust port 71, thereby operation surface 2 can make oiling agent 8 along the circumferential direction be applied in the zone that can be limited by the geometrical shape of oiling agent beam 9 on it.In this respect, each oiling agent nozzle 7 can be disposed in the groove 6 of cylinder wall 3, thus oiling agent beam 9 in a mode that cardinal principle is tangent, but be to discharge from oiling agent nozzle 7 about the predetermined angle of cylinder axis 10 separately.Therefore oiling agent beam 9 can be applied on the circumferencial direction of cylinder 4 on the operation surface 2 spirally along one of both direction of cylinder axis 10.Oiling agent beam 9 also can be discharged perpendicular to cylinder axis 10 and generally along a tangential direction ground naturally, thereby oiling agent 8 can the main in a circumferential direction mode with a plane be applied on the operation surface 2, promptly is not in a spiral manner.
In this respect, oiling agent beam 9 or at piston through before the groove 6 and/or in the process and/or be applied to by oiling agent nozzle 7 with a kind of pulse mode afterwards on the operation surface 2, along the circumferential direction and in axial direction be distributed evenly on the operation surface 2 of cylinder wall 3 simultaneously in addition by the motion of piston 5 or the motion of piston ring 54.The amount and the timing of the oiling agent that distributes at each oiling agent nozzle 7 place can be optimized by the corresponding control or the adjusting of control unit 14 by means of measuring unit 13.In order to make the amount minimum of used oiling agent 8, the supply of oiling agent 8 on operation surface 2 can stop for example one or more work cycle of reciprocating internal combustion engine, and therefore the consumption of used oiling agent 8 just can further be reduced.Cylinder wall 3 can have one or more grooves 11 that extend in a circumferential direction, can store a certain amount of oiling agent that applies 8 in these grooves.For example, a certain amount of oiling agent 8 that is on the operation surface 2 can be scraped in the groove 11 by piston ring 54, and temporarily be stored in there, can get back to operation surface 2 from described groove 11 at time oiling agent 8 after a while, thereby help once more to lubricate, i.e. a process that helps the saving of oiling agent 8 equally substantially.
Particularly guaranteed by layout and design according to the oiling agent nozzle of lubrication system of the present invention: oiling agent is applied directly on the operation surface of cylinder wall of cylinder of reciprocating internal combustion engine.In this respect, lubrication system according to the present invention is characterised in that it especially simply designs, the particularly design of oiling agent nozzle, wherein, because their simple designs, the supplementary equipment therefore member that cost drives, for example spill pipe or similar component just can omit.Have found that, therefore compared with prior art can obtain a kind of oiling agent more uniformly applies, be that oiling agent can in axial direction be distributed on the operation surface of cylinder with circumferencial direction simultaneously ideally, thereby the wearing and tearing on the operation surface of the operation surface of cylinder or piston just can be reduced a lot.Because oiling agent is applied directly on the operation surface, by an intermediate steps, for example by the oiling agent beam to the airborne atomizing of scavenging, so guaranteed institute's economic especially and use effectively with lubricator.
