Description

Especially combined type waste gas distributor of internal-combustion piston engine and waste gas distribution circuit
Technical field
The present invention relates to a kind of internal-combustion piston engine (Hubkolbenbrennkraftmaschine) and especially longitudinalScavenging type large-sized two-stroke diesel engine and waste gas distributor.
Background technology
The large-sized diesel motor of cross head design form (as preferably in Ship Structure or fixed equipment for exampleBe used to produce electric energy) comprise three large-scale shell part that form engine frame. Except being useful on, band holding songThe supporting saddle of the bent axle seat of honour of axle also has outward on the substrate of lateral support member, is provided with separatedly so-called by base platePillar. Known pillar comprises multiple opposed supporting masses, each supporting mass according to the number of cylinders of large-sized diesel motorThere is vertically extending sliding surface for guiding two adjacent (joining by push rod and bent axle) crossheads. ThisTime, corresponding two opposed vertically extending supporting masses (comprising sliding surface) carry out additional support by midfeather. ThisA little supporting masses interconnect by same cover plate conventionally. So, above pillar, arrange and be also often called as at cover plate placeThe cylinder portion section of cylinder jacket, it is applicable to hold multiple cylinder sleeves. Described base plate, pillar and cylinder portion section are now by drawingBar (generally extending in supporting mass in post area) so interconnects, that is, this pull bar is done at significant pretensionWith under be bolted among substrate or on.
In addition known the pillar of the different problems that various dissimilar replies are relevant with wearing and tearing from stability, Qi ZhongThe solution of corresponding optimization has been proposed in prior art.
In order to increase piston internal-combustion acc power, but not only especially for the internal combustion engine of this above-mentioned type, firingBurn after stroke, new wind is sent under the pressure increasing by the supercharging group that generally comprises at least one exhaust-driven turbo-charger exhaust-gas turbo chargerEnter cylinder sleeve combustion chamber. Now can make full use of the part heat of the waste gas that leaves cylinder sleeve combustion chamber after combustion strokeEnergy. For this reason, the waste gas of heat is supplied to from cylinder sleeve combustion chamber by the outlet valve of opening in the cylinder cap of being for example located at cylinder sleeveThis supercharging group. This supercharging group is generally made up of turbine at this, and it is by flowing under pressure into heating useless of supercharging groupGas drives. Turbine is drive compression machine again, sucks thus new wind and compresses. At the compressor with turbine(except title exhaust-driven turbo-charger exhaust-gas turbo charger, be also conventionally called turbocharger for short and be not especially onlyThe device forming mainly with radial compressor form greatly in large-sized two-stroke diesel engine situation) downstream, what is called is setDiffuser, charger-air cooler, separator and air inlet reservoir, from here, compress new wind and (also claimedFor pressurized air or scavenging air) be finally admitted to some combustion chambers of the cylinder sleeve of large-sized diesel motor. Therefore, logicalCross and use such supercharging group, can increase fresh air supply and improve the effect in the indoor combustion process of cylinder combustionRate.
In large-sized diesel motor situation, realize at the different parts of cylinder sleeve and send into air according to type. Therefore,For example, in longitudinally scavenged formula two stroke engine, air is via in the working surface being arranged in cylinder sleeve underside areaScavenging sews sends into cylinder sleeve combustion chamber. Under mini four-stroke engine conditions, pressurized air is generally via one or manyThe individual inlet valve being for example arranged in cylinder head is admitted to combustion chamber of air cylinder. In addition, certainly also know two stroke engine,It replaces the scavenging seam in cylinder sleeve underside area and is equipped with the inlet valve of being located at cylinder sleeve top.
In order to understand better the present invention that also will describe subsequently, Fig. 1 is for illustrating the cooperation of different partsSchematic diagram illustrates from prior art the principle of the exhaust-driven turbo-charger exhaust-gas turbo charger system of disclosed large-sized diesel motor so farProperty structure, this large-scale diesel engine with have longitudinally scavenged function large-sized two-stroke diesel engine form form and withTotally indicate with Reference numeral 1 ' down.
In order to distinguish better the present invention and prior art, the accompanying drawing relevant to the feature of the disclosed example of prior artMark is with respectively single quotation marks, and the Reference numeral that relates to the embodiment of the present invention is not with single quotation marks.
Conventionally, large-scale diesel engine 1 ' comprises air cylinder group GZ ' according to known way own, and it comprises multiple cylinder sleeve GZ1 ',Cylinder sleeve has the intake valve 3 ' of being located in cylinder cap, in described cylinder sleeve GZ1 ', piston K ' with can be at bottom dead centre UT ' andThe mode moving back and forth along working face between top dead-centre OT ' arranges. The casing wall of cylinder sleeve GZ1 ' is together with cylinder cap and piston K 'Limit the combustion chamber 2 ' of cylinder sleeve GZ1 ' according to known way.
Consider for general view, in Fig. 1, only illustrate a cylinder sleeve GZ1 '. Obviously, described gas in practiceCylinder group G ' comprises multiple and is generally a large amount of cylinder sleeve GZ1 '.
In the underside area of cylinder sleeve GZ1 ', be provided with multiple scavenging air openings 9 ', they form with scavenging seam form.According to the position of piston K ', scavenging sews piston and shelters from or open. By scavenging air opening 9 ', be called as and sweepThe pressurized air of gas air 81 ' can flow into the combustion chamber 2 ' of cylinder sleeve GZ1 '. Be located at the outlet valve 3 ' in cylinder cap by mistake,The waste gas 5 ' producing when burning flow through waste gas header 4 ' (its via outlet valve 3 ' under its open mode with each spontaneous combustionFlow and be communicated with in chamber 2 ') flow into the supercharging group 71 ' forming as exhaust-driven turbo-charger exhaust-gas turbo charger.
The exhaust-driven turbo-charger exhaust-gas turbo charger of supercharging group 71 ' as mentioned above according to known way own as chief component wrapDraw together and be with compressor and the band of the compressor impeller 711 ' that is useful on air 80 ' compression to be useful on drive compression machine impellerThe turbine of 711 ' turbine wheel 712 ', compressor impeller by axle according to known way effectively stably withTurbine wheel 712 ' connects. Described turbine and compressor are arranged in a housing and therefore form described waste gasTurbocharger, it forms mainly with radial compressor form greatly. Described turbine passes through from cylinder sleeve according to known wayThe heat exhaust gases 5 ' of the inflow of the combustion chamber 2 ' of GZ1 ' is driven.
In order to give combustion chamber 2 ' the filling scavenging air 81 ' of cylinder sleeve GZ1 ', by compressor impeller 711 ' via air-breathingTake over compressed exhaust-driven turbo-charger exhaust-gas turbo charger from environment air amount 80 ' and this air. Compressed air 80 ' is from uselessAir turbine booster enters through separator 740 ' by diffuser 720 ' and the charger-air cooler 730 ' of being located at downstreamEnter air inlet reservoir 750 ', from here, compressed air 80 ' finally stitches shape as scavenging air 81 ' by being scavengingThe scavenging air opening 9 ' that formula forms is increasing the combustion chamber 2 ' that enters cylinder sleeve GZ1 ' under pressure.
Utilize one or more turbocharger to the principle of engine filling pressurized air very early for likelyThe engine of type be known and correspondingly as far back as decades ago with regard to successful Application in large-scale two punchings of longitudinally scavenged formulaIn journey Diesel engine. In addition, during this period, along with progressively development, by waste gas header with comprise diffuser, superchargingThe shape design of the waste gas system that the above-mentioned turbo charge system of aerial cooler and separator forms and layout are alwaysBe further optimized, therefore, known waste gas system is also economized local ground the best this moment and is incorporated to engine overall shape very muchIn. This in the longitudinally scavenged formula large-sized two-stroke diesel engine being installed in boats and ships, be especially one very importantPoint because operational space is few in principle in hull, thereby is saved the building block of arranging engine locallyIt is a key factor.
But, be exactly to occur in recent years in this obvious problem, especially becoming more and more stricter waste gas markIn standard, can find the cause of described problem, first therefore this do not expect to see.
Because waste gas regulation becomes more and more stricter, in recent years the requirement of exhaust mass was become to more and more, at thisIn, not only have but especially the nitrous oxides concentration in waste gas be the focus of waste gas standard. Here, for correspondingIt is more and more stricter that the legal provisions of waste gas limiting value and limiting value always become. This especially starts at large-sized two-stroke dieselIn machine, cause the burning of the typical heavy oil that contains a large amount of nuisances and the burning of diesel oil or other fuel to be always a problem, this is more and more difficult and become increasingly complex technically because observe waste gas limiting value, thereby more expensive, evenWorry to observe waste gas limiting value and finally even may no longer include meaning.
Therefore do about waste gas purification, keyword " exhaust gas catalyzer " and substituted type fuel in recent years in practice,Go out great efforts. Therefore, additionally or alternatively, required very early for the same reason so-called " twoEngine fuel ", the engine that can drive with two kinds of different fuel. In gaseous state pattern, combustion gas is as naturalFor example LNG of gas (liquefied natural gas) or be the combustion gas of automotive natural gas form or other is suitable for driving the combustion of internal combustion engineGas firing, and in liquid mode, suitable liquid fuel is as gasoline, diesel oil, heavy oil or the combustion of other suitable liquid stateMaterial can burn in same engine. At this, this engine can be two stroke engine and four-stroke engine,And it can be put-put or medium-and-large-sized engine at this, but can be also big-block engine, especially also canIt is longitudinally scavenged formula large-sized two-stroke diesel engine.
Therefore, within the scope of the present invention, except representing typically with heavy oil or bavin with term " large-sized diesel motor "Outside the large-sized two-stroke diesel engine that oil drives, also represent such big-block engine with this term, it is except pressingOutside the diesel engine operation taking fuel spontaneous combustion as feature, also can be according to the external source igniting operation of source fire fuel in addition(Ottobetrieb) or both mixed forms turn round. In addition, term " large-scale diesel engine " especially also comprises instituteState dual fuel engine and such big-block engine, wherein lighting by being lighted a fire by the external world of other fuel of fuelStart.
In liquid mode, fuel conventionally by nozzle by direct cylinder injection combustion chamber there according to spontaneous combustion principleBurning. In gaseous state pattern, be known that the combustion gas under gaseous state mixes with scavenging air according to external source ignition principle, withJust the mixture that therefore can light in the indoor generation of cylinder combustion. In such low pressure method, conventionally so mixCompound lighting in cylinder, in the correct moment, a small amount of liquid fuel is injected into combustion chamber of air cylinder or cup, its withAfter caused lighting of air-natural gas mixture. Dual fuel engine conventionally also can be from gaseous state in operation workPattern is switched to liquid mode, otherwise or.
But, also investigated simple gas engine, can only with combustion gas carry out work and can not be alternatively also with diesel oil,Heavy oil or other fuel carry out the engine of work, and especially, in the time requiring high waste gas standard, this high waste gas standard can only be paidGo out rational technique become local and economically meaningful Shangdi observe by gas-firing, can be also therefore followingFurther described subject matter of an invention.
No matter it be whether dual fuel engine, simple gas engine or with liquid fuel as gasoline, diesel oil or heavyThe engine that oil drives or the mixed type of above-mentioned engine type, all inevitably will be disposed at waste gas in the futureBefore environment, utilize suitable equipment and method to purify or this waste gas of pretreatment.
Especially in order to reduce nitrogen oxide in waste gas and known employing waste gas reaction device and especially so-called " SCRReactor ".
Term " SCR " is English " SelectiveCatalyticReduction (SCR) " at thisAbbreviation and can in spoken language, be called as " catalyst converter ", it reduces the nitrogen oxide in waste gas. If it is notJust working in SCR reactor as in for example with the automobile of platinum catalyst converter material, catalyst converterElement is for example made up of pottery or metal and has a special reaction coating. But reduction reaction and coating only go out relativelyWhen for example urea of chemical substance that present waste gas is prior and suitable or ammonia mix, described chemical substance must be steamed in waste gasSend out ammonification.
For described mixing and evaporation, from prior art, know, before entering SCR reactor, as mixedClose the certain length of mixing section that evaporation tube forms and be given for reactive material mixing and evaporation as urea and waste gas.In order to ensure to mix reliably and evaporation, this mixing section is so far with having between waste gas header and SCR reactorThe mixed pipe line form of certain minimum length arranges. But because the mixing tube the solution known from prior artExtend from engine as described in also illustrating in conjunction with Fig. 2 below on road, therefore mixing from the known big-block engine of prior artClose pipeline and in hull, occupy very large structure space, be therefore an impediment to cramped construction.
But, be not the valuable structure space that only has such a mixed pipe line requested number considerable. Conventionally be exactly at toolThere are multiple cylinder sleeves, as 6,8,10,12 or even need to arrange two in the large-sized diesel motor of 14 cylinder sleevesOr even more than the supercharging group with turbocharger of two, replace an only supercharging group, and here, so far existingHave in technology, for each turbocharging, the whole device being made up of mixed pipe line and waste gas reaction device is set separately, this certainlySo determine additionally taking in a large number of structure space.
Illustrate the problems referred to above in conjunction with schematic diagram 2, Fig. 2 is for only having in the situation of unique turbochargerShow the large-scale bavin that comprise waste gas header, mixed pipe line, SCR reactor and supercharging group known from prior artOil turbine. If be provided with multiple turbocharger, in the prior art so far for each independent turbochargingDevice is isolated system being made up of mixed pipe line and SCR reactor of relative set respectively. Here, at this, go outConsider in place and abandoned this view with multiple turbocharger, especially because for technical staff,From Fig. 2, arbitrarily obtain the general layout structure with multiple turbocharger.
Fig. 2 illustrates a kind of known large-scale diesel engine 1 ', and it has waste gas header 4 ' and is for example for waste gas 5 ', at thisThe mixing section 12 ' of the mixed pipe line 121 ' form of mixing with urea, urea is evaporated into ammonia in waste gas 5 '. As above instituteState, for enter as shown in the figure SCR reactor 6 ' before urea mix and evaporation with the reliable of waste gas 5 ', necessaryGuarantee be mix evaporation tube form mixing section 12 ' and and then the specific minimum length of mixed pipe line 121 '. ForCan observe the minimum length of mixed pipe line 121 ' between waste gas header 4 ' and SCR reactor 6 ', from existing skillArt known according in the large-sized diesel motor of Fig. 2, mixed pipe line 121 ' first via connector 122 ' from startingMachine extends, thereby has the space that is enough to be used in observing needed mixed pipe line 121 ' minimum length.
Also can directly from schematic diagram 2, see without further illustrating, what really ensured urea by this structure canBy evaporation and with the mixing of waste gas 5 ' that enters mixed pipe line 121 ' from waste gas header 4 '. This structure needs but thenWill not acceptable large space, this large space in hull, be especially cannot provide or at other side energy quiltMore good utilisation.
In addition, this structure also has other debatable performance that for example technical staff finds at once. A, weightThe own known problem of wanting is vibrated exactly, this vibration conventionally can have up to even exceed 10000KW power/The in service of the monoster engine of cylinder is introduced into surrounding environment and is equiped with in the building block of installation of this engine. ThisOutward, current known marine engine for example has nearly 12 cylinders or 40 cylinders even conventionally, and described cylinder is in fortuneIn row state, so strong vibration can be introduced to hull and especially also introduce the parts that are arranged on engine for example uselessGas system, catalyst system and the turbo-charger sytem with supercharging group, result, is not specifying suitable replyMeasure is as in vibration compensation device situation, they may be badly damaged or even be out of order. But according to the SCR of Fig. 2In this floating structure of catalyst system, known vibration compensation device is also no longer enough to prevent for a long time this knot conventionallyStructure is impaired.
But, additional line part and associated for example passing through just as being for example arranged in the large-scale diesel engine of Fig. 2Mixed pipe line 121 ' and SCR reactor 6 ' and the connector 122 ' between SCR reactor 6 ' and supercharging group 71 'Or the longer waste gas streams path of other tube-carrier fitting is not also desirable and except undesirable materialConsumption also brings other passive technique effect outward, for example temperature of the waste gas 5 ' in pipe-line system and/or pressure drop,This has finally reduced turbo power and has brought known for technical staff itself thereupon and naturally do not wishAnd thereby a series of other the passive technique influences that will as far as possible avoid.
Summary of the invention
Therefore,, in view of this prior art, task of the present invention is propose a kind of improved engine and especially haveExhaust gas catalyzer system is the crosshead type large Diesel engine of SCR reactor especially, at this, from prior artKnown shortcoming is avoided and is especially obtained saving local waste gas system layout and the outlet at cylinder sleeve as far as possibleValve and with the shortening of the flow-path-length between the supercharging group of turbocharger. Another task of the present invention is to carryFor especially large-sized two-stroke diesel engine of a kind of internal-combustion piston engine, can under similar load condition, save whereby and send outMotivation fuel also can totally reduce toxic emission.
Therefore, the present invention relates to the especially longitudinally scavenged formula large-sized two-stroke diesel engine of a kind of internal-combustion piston engine,Comprise the air cylinder group of multiple cylinder sleeves, each air cylinder group has a combustion chamber and each self-corresponding outlet valve, wherein, and instituteSo flow and be communicated with same waste gas header in each combustion chamber of stating the air cylinder group of cylinder sleeve, in running status, uselessGas can be supplied to this waste gas header via each self-corresponding outlet valve from each combustion chamber of the air cylinder group of described cylinder sleeve,And in order to process, waste gas can in servicely be admitted to waste gas reaction device from waste gas header purifying. In addition, establishBe useful on the supercharging device of air compressing, it comprises the first supercharging group and the second supercharging group, from giving up of waste gas reaction deviceGas can in servicely be supplied to these supercharging groups purifying, thereby makes by the first supercharging group and the second supercharging group compressedAir can via each self-corresponding scavenging air opening as scavenging air be supplied to one or more cylinder sleeves and/or shouldOne or more cylinder sleeves of air cylinder group. According to the present invention, waste gas distribution circuit is so near cylinder sleeve and in being basically parallel toCombustion machine crankshaft ground is the first supercharging group and the second supercharging group on the one hand and is the region between waste gas header on the other handInterior extension, thus make this waste gas to be supplied to the first supercharging group via crossing waste gas distribution circuit from waste gas reaction deviceWith the second supercharging group. .
Therefore, for the present invention importantly, waste gas distribution circuit is so close to cylinder sleeve and is basically parallel to internal combustionBe arranged on machine crankshaft and be on the one hand the first supercharging group and the second supercharging group and be the district between waste gas header on the other handIn territory, that is, waste gas can be supplied to the first supercharging group and second via this waste gas distribution circuit from this waste gas reaction deviceSupercharging group. In brief, between waste gas header and the exhaust-driven turbo-charger exhaust-gas turbo charger of supercharging group, be provided with waste gas according to the present inventionDistribution circuit, pretreated the process from waste gas reaction device waste gas is distributed to turbocharger by waste gas distribution circuit.Thus, can effectively realize first in big-block engine and especially longitudinally scavenged formula large-sized two-stroke diesel engineAlso can increase distribute to multiple supercharging groups or its exhaust gas turbine from the treated waste gas of same waste gas reaction deviceDepressor.
Be different from so far from the known engine of prior art and (wherein needn't arranging separately by mixed pipe line and waste gasMust be separately in self general arrangement situation that reactor forms arrange at least one oneself to each turbochargerWaste gas reaction device, this has caused the above-mentioned structure space that additionally takies in a large number), can realize for the first time by the present inventionEspecially for thering are multiple cylinder sleeves for example 6,8,10,12 or large-scale diesel engine (the cylinder sleeve of 14 cylinder sleeves evenThe each personal exhaust-driven turbo-charger exhaust-gas turbo charger of at least two supercharging groups drive), unique waste gas reaction is only setDevice or unique device being made up of mixed pipe line and waste gas reaction device is only set, treated waste gas is subsequently from thisIn be assigned to each supercharging group.
In addition, in engine of the present invention, under concrete condition obviously also can be especially for thering are multiple cylinder sleevesEngine considers for example to arrange at least two waste gas reaction devices or at least two by mixed pipe line and useless for certainThe device that solid/liquid/gas reactions device forms, at this, one of them described waste gas reaction device or one of them is described by mixingThe device that closes pipeline and waste gas reaction device formation flows and is communicated with a waste gas distribution circuit respectively, distributes by this waste gasPipeline, waste gas can be assigned at least two supercharging groups from same waste gas reaction device.
By the present invention, can be whereby not only save for the first time lower profuse structure space, this be because, on the one hand,The quantity of the device that the quantity of waste gas reaction device is made up of mixed pipe line and waste gas reaction device in other words can be reduced to absolutelyTo minimum, wherein under vantage, need only also arrange a waste gas reaction device in other words one by mixed pipe line and uselessThe device that solid/liquid/gas reactions device forms. And, only pass through according to the present invention very compactly in the supercharging group with turbochargerAnd between waste gas header, arrange waste gas distribution circuit, just save appreciable structure space.
But in addition also simultaneously by the invention solves a series of other the problems referred to above of knowing from prior art.
Therefore,, in device according to the present invention, obviously alleviate to be attended by by the above-mentioned of vibration that cause of operation motor and askTopic, this is finally especially determined by compact structure. Therefore, by the present invention, by structures shape based on whole uselessIt is impaired that the compact Layout form of gas system and cramped construction have significantly reduced the waste gas system that caused by caused vibrationDanger, this waste gas system comprise waste gas header, perhaps with the waste gas reaction device of mixed pipe line, with supercharging groupTurbo charge system and waste gas distribution circuit, thus in engine of the present invention conventionally without taking addition thereto to subtractLittle vibration in the building block of the waste gas system vibration of whole waste gas system in other words, because this can say by structureDetermine automatically to have accomplished.
The compact Layout of waste gas system of the present invention and structure are especially also brought other good effect, that is, no longer need andThereby can save the above-mentioned additional line part in waste gas system. Thus, that from prior art, know and naturally not uncommonThe longer exhaust flow path that prestige has is avoided by the present invention. Therefore, not only saved for no longer needingThe material of additional line part, and reliably avoided by the unnecessary length in the disclosed waste gas system of prior artOther passive technique effect of causing of path. Therefore, for example obviously reduced the temperature of the waste gas in waste gas systemDegree reduces and/or pressure decreased, and this has improved the power of turbocharger, and thus one, final for example similarUnder load condition, also can save engine fuel, and also reduce generally toxic emission, this finally also has environmentGood effect.
In addition, the disappearance of additional line part has yet been improved vibration behavior, because owing to there is no additional line part, described inThe structure of waste gas system and arrange totally compactlyer and finally from vibrotechnique rigidity more, therefore, institute drawsThe vibration rising can better be compensated or can be can't help for the first time waste gas system or its building block completely and be born, and thenAlso further reduce impaired Potential feasibility.
For putting into practice in a particularly preferred embodiment,
Internal-combustion piston engine is big-block engine and especially longitudinally scavenged formula large-sized two-stroke diesel engine, and shouldWaste gas distribution circuit is more or less directly placed in waste gas header below, is the first increasing about being vertically placed on the one handPressure group and the second supercharging group and be between waste gas header on the other hand, and near cylinder sleeve described in one of them.
Thus one, especially obviously shortened and saved to the air inlet pipeline of the exhaust-driven turbo-charger exhaust-gas turbo charger of supercharging groupImportant place, described important place for example can supply power operation platform and maintenance work or other operation to make subsequentlyWith, on power operation platform, for example maintenance mans and other personnel can move on engine. In addition, by shorteningPipeline avoid at least a portion pressure loss, and also actively have influence on the intrinsic frequency of waste gas system and especiallyThe intrinsic frequency of waste gas header, thus one, can save materials and only just reduce thus for these building blocksCost.
In another embodiment that is perhaps better adapted to concrete internal combustion engine of the present invention, waste gas distribution circuit also canBe placed in turbocharger front, about being vertically placed on the height of the first supercharging group and the second supercharging group, at thisIn, waste gas distribution circuit is arranged between the first supercharging group and the second supercharging group and near cylinder sleeve described in one of them.
In addition, the length of waste gas distribution circuit preferably can be in all embodiment of the present invention about waste gas header by asThis shortens, that is, waste gas distribution circuit just can also flow and be communicated with all corresponding exhaust-driven turbo-charger exhaust-gas turbo chargers, but at itIts its length of place is no more than the border of the device being made up of turbocharger.
According to the project organization of waste gas system, in practice except waste gas header and waste gas distribution circuit, can also asThis setting and layout are for mixing with waste gas and evaporating reactive material, and as the mixing section of urea, that is, waste gas can be via thisMixing section is supplied to waste gas reaction device, here, this mixing section specifically can with waste gas header and waste gas reaction device itBetween mixed pipe line form arrange, therefore, reactive material evaporation and and waste gas that waste gas can be by mixing sectionMix subsequently in waste gas reaction device by reliable treatments.
In addition, in a specific embodiment of the present invention, this mixing section can be at least partly but preferably fully byBe integrated in waste gas header and/or waste gas header itself can form as mixing section. Thus, obviously also further saveValuable local and finally also further minimum material consumption and cost.
Also feasible in another embodiment, this mixing section at least partly but be preferably integrated in fully waste gasIn reactor, or obviously also feasible, this waste gas reaction device and this waste gas distribution circuit form one common wholeBody formula assembly.
In addition, described waste gas header, mixing section, waste gas reaction device, especially can be with one together with waste gas distribution circuitCommon integral component form forms, and this integral component is preferably to be arranged essentially parallel to the mode of bent axle of internal combustion engineOn the one hand near the first supercharging group and the second supercharging group with on the other hand near extension in the region of cylinder sleeve.
Obviously in practice commonly, this waste gas reaction device needn't move for a long time, for example, ought have engine of the present inventionShip's navigation in certain region that does not have corresponding strict waste gas regulation time, therefore, for example, go out from economic angleSend out or maybe advantageously temporarily do not make for maintenance work the work of waste gas reaction device.
Therefore can advantageously so arrange and arrange bypass line, make waste gas walk around can in waste gas reaction device situationTo be supplied to waste gas distribution circuit further to guide to corresponding supercharging group or turbocharger, that is, waste gas canWalk around waste gas reaction device via bypass line, thereby waste gas no longer flows through waste gas reaction device. For this reason, described other bypassPipeline for example can be arranged between waste gas header and waste gas distribution circuit.
Described bypass line itself for example can be arranged to by by-passing valve locking, wherein said other bypass line itselfAlthough not necessarily but advantageously can form as by-passing valve depending on embodiment. In other words, this by-passing valve playsBypass line effect, this especially can in the time that for example waste gas distribution circuit next-door neighbour waste gas header is for example arranged with it abreastCan be favourable.
In addition, obviously this waste gas header also can pass through waste gas header valve by locking like this, that is, and and when waste gas purification or uselessWhen gas disposal does not need as mentioned above, waste gas cannot be supplied to waste gas from waste gas header again in such running statusReactor. For this object, waste gas distribution circuit also can be passed through waste gas distributing valve by locking like this, that is, and and waste gasCannot be supplied to this waste gas distribution circuit from waste gas reaction device again.
