Description

Internal-combustion piston engine and the guide tank for waste gas header

Technical field

The present invention relates to a kind of internal-combustion piston engine and the guide tank of especially longitudinally scavenged formula large-sized two-stroke diesel engine and the waste gas header for internal-combustion piston engine.

Background technique

The large-sized diesel motor (producing electric energy as being preferably such as used in Ship Structure or fixed equipment) of cross head design form comprises three the large-scale shell part forming engine frame.Also having the substrate of lateral support member except the supporting saddle with the bent axle seat of honour for holding bent axle, be provided with so-called pillar separatedly by base plate.Known pillar comprises multiple opposed supporting mass according to the cylinder number of large-sized diesel motor, each supporting mass have vertically extending slip surface for guide two adjacent (by push rod and bent axle joining) crosshead.Now, corresponding two opposed vertically extending supporting masses (comprising slip surface) carry out additional support by midfeather.These supporting masses are interconnected by same cover plate usually.So arrange the cylinder part section being also often called as cylinder liner above pillar at cover plate place, it is applicable to hold multiple cylinder sleeve.Described base plate, pillar and cylinder part section are now so interconnected by pull bar (generally extending in supporting mass in post area), that is, this pull bar to be bolted under significant pretension effect among substrate or on.

In addition be aware of various dissimilar reply and the pillar of stability with relevant different problems of wearing and tearing, wherein propose the solution of corresponding optimization in the 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, after combustion stroke, new wind is admitted to cylinder sleeve firing chamber under increased pressure by the supercharging group generally comprising at least one exhaust-gas turbocharger.Now can make full use of a part of heat energy of the waste gas leaving cylinder sleeve firing chamber after combustion stroke.For this reason, the waste gas of heat is supplied to this supercharging group by opening the outlet valve be such as located in the cylinder cap of cylinder sleeve from cylinder sleeve firing chamber.This supercharging group is generally made up of turbo machine at this, and it is driven by the waste gas flowing under pressure into the heating of supercharging group.Turbo machine drives compressor again, sucks new wind thus and compresses.In compressor (be namely also usually called turbosupercharger for short except title exhaust-gas turbocharger and be not especially only in large-sized two-stroke diesel engine situation greatly mainly with the device that the radial compressor form is formed) downstream with turbo machine, so-called Diffuser, charger-air cooler, separator and air inlet reservoir are set, from here, compress some firing chambers that new wind (being also referred to as pressurized air or scavenging air) is finally admitted to the cylinder sleeve of large-sized diesel motor.Therefore, by using such supercharging group, fresh air supply can be increased and the efficiency of the combustion process of raising in cylinder combustion indoor.

In large-sized diesel motor situation, realize sending into air at the different parts of cylinder sleeve according to type.Therefore, such as, in longitudinally scavenged formula two stroke engine, air sews via the scavenging in the working surface be arranged in cylinder sleeve underside area and sends into cylinder sleeve firing chamber.Under mini four-stroke engine conditions, pressurized air is generally admitted to combustion chamber of air cylinder via one or more intake valve be such as arranged in cylinder head.In addition, certainly also know two stroke engine, it replaces the seam of the scavenging in cylinder sleeve underside area and is equipped with the intake valve being located at cylinder sleeve top.

In order to understand the present invention that also will describe subsequently better, Fig. 1 is for illustrating that the schematic diagram of cooperation of different constituent element illustrates the principle structure of the exhaust-gas turbocharger system of disclosed large-sized diesel motor so far from prior art, and this large-scale diesel engine is formed with the large-sized two-stroke diesel engine form with longitudinally scavenged function and following overall by reference numeral 1 ' indicates.

In order to distinguish the present invention and prior art better, the reference character relevant to the feature of the example disclosed in prior art is with single quotation marks respectively, and the reference character relating to the embodiment of the present invention is not with single quotation marks.

Usually, large-scale diesel engine 1 ' comprises cylinder block GZ ' according to known way own, it comprises multiple cylinder sleeve GZ1 ', cylinder sleeve has the suction valve 3 ' be located in cylinder cap, in described cylinder sleeve GZ1 ', piston K ' is arranged in the mode that can move back and forth along working surface between lower dead centre UT ' and upper dead center OT '.The casing wall of cylinder sleeve GZ1 ' limits the firing chamber 2 ' of cylinder sleeve GZ1 ' together with cylinder cap and piston K ' according to known way.

Consider for general view, only illustrate a cylinder sleeve GZ1 ' in FIG.Obviously, described cylinder block G ' comprises multiple and is generally a large amount of cylinder sleeve GZ1 ' in practice.

In the underside area of cylinder sleeve GZ1 ', be provided with multiple scavenging air opening 9 ', they are formed with scavenging seam form.According to the position of piston K ', scavenging sews piston and shelters from or open.By scavenging air opening 9 ', the pressurized air being called as scavenging air 81 ' can flow into the firing chamber 2 ' of cylinder sleeve GZ1 '.By crossing the outlet valve 3 ' be located in cylinder cap, the waste gas 5 ' produced during burning flows through waste gas header 4 ' (it flows with respective firing chamber 2 ' via outlet valve 3 ' and is communicated with under its open mode) and flows into the supercharging group 71 ' formed as exhaust-gas turbocharger.

The exhaust-gas turbocharger of supercharging group 71 ' comprises with the compressor of the compressor impeller 711 ' compressed for air 80 ' and the turbo machine with the turbine wheel 712 ' for driving compressor impeller 711 ' according to known way own as chief component as mentioned above, and compressor impeller is effectively stably connected with turbine wheel 712 ' according to known way by an axle.Described turbo machine and compressor are arranged in a housing and also therefore form described exhaust-gas turbocharger, and it is formed mainly with radial compressor form greatly.Described turbo machine is driven by the heat exhaust gases 5 ' from the inflow of the firing chamber 2 ' of cylinder sleeve GZ1 ' according to known way.

In order to give firing chamber 2 ' the filling scavenging air 81 ' of cylinder sleeve GZ1 ', suck air 80 ' and this air exhaust-gas turbocharger compressed via air-breathing adapter from environment by compressor impeller 711 '.Pressurized air 80 ' enters air inlet reservoir 750 ' by the Diffuser 720 ' and charger-air cooler 730 ' being located at downstream through separator 740 ' from exhaust-gas turbocharger, from here, the scavenging air opening 9 ' that pressurized air 80 ' is finally consisted of the seam form in scavenging as scavenging air 81 ' is increasing the firing chamber 2 ' entering cylinder sleeve GZ1 ' under pressure.

Utilize one or more turbosupercharger to the principle of motor filling pressurized air very early for the motor of likely type be known and correspondingly as far back as decades ago with regard to successful Application in longitudinally scavenged formula large-sized two-stroke diesel engine.In addition, during this period, along with progressively developing, profile design and the layout of the waste gas system be made up of with the above-mentioned turbo charge system comprising Diffuser, charger-air cooler and separator waste gas header are always being further optimized, therefore, known waste gas system is also economized local ground the best this moment and is incorporated in engine total shape very much.This is especially a very important point being installed in the longitudinally scavenged formula large-sized two-stroke diesel engine in boats and ships, because operational space is few in principle in hull, thus saves and arranges that the constituent elements of motor is a key factor locally.

But be exactly occur obvious problem in recent years in this, especially becoming the cause that can find described problem in more and more stricter emissions standards, therefore this first undesirably see.

Because waste gas regulation becomes more and more stricter, in recent years the requirement of exhaust mass was become more and more, here, not to only have but nitrous oxides concentration especially in waste gas is the focus of emissions standards.Here, always become more and more stricter for the legal provisions of corresponding waste gas limiting value and limiting value.This especially causes the burning of the burning of the typical heavy oil containing a large amount of harmful substance and diesel oil or other fuel always debatable in large-sized two-stroke diesel engine, this is because it is more and more difficult and become increasingly complex technically to observe waste gas limiting value, thus costly, even worry that observing waste gas limiting value finally even may no longer include meaning.

Therefore in practice, great efforts has been made about waste-gas cleaning, keyword " exhaust gas catalyzer " and substituted type fuel in recent years.Therefore, namely additionally or alternatively, required very early so-called " duel fuel engine " for the same reason, the motor that can drive with two kinds of different fuel.In gas mode, combustion gas as rock gas such as LNG (LNG Liquefied natural gas) or in the combustion gas of automotive natural gas form or other be suitable for the fuel gas buring driving internal-combustion engine, and in liquid mode, suitable liquid fuel such as gasoline, diesel oil, heavy oil or other suitable liquid fuel can burn in same motor.At this, this motor can be two stroke engine and four stroke engine, and it can be mini engine or medium-and-large-sized motor at this, but also can be big-block engine, especially also can be longitudinally scavenged formula large-sized two-stroke diesel engine.

Therefore, within the scope of the present invention, except represent the large-sized two-stroke diesel engine that typically drives with heavy oil or diesel oil with term " large-sized diesel motor " except, also represent such big-block engine with this term, it is except running according to the diesel engine that is feature with fuel spontaneous combustion, also can run (Ottobetrieb) according to the external source igniting of source fire fuel in addition or both mixed forms operate.In addition, term " large-scale diesel engine " especially also comprises described duel fuel engine and such big-block engine, and wherein lighting of fuel starts by the external world's igniting by other fuel.

In liquid mode, fuel is usually injected directly combustion chamber of air cylinder by nozzle and burns according to spontaneous combustion principle there.Combustion gas in gas mode it is known that under gaseous state mixes with scavenging air according to external source ignition principle, so that therefore at the mixture that the indoor generation of cylinder combustion can be lighted.In such low pressure method, usually so carry out mixture lighting in cylinder, namely in the correct moment, a small amount of liquid fuel is injected into combustion chamber of air cylinder or cup, and it result in lighting of air-natural gas mixture subsequently.Duel fuel engine also can be switched to liquid mode from gas mode usually in operation work, otherwise or.

But, also simple gas engine has been investigated, namely can only carry out work with combustion gas and alternatively also can not carry out the motor of work with diesel oil, heavy oil or other fuel, especially when requiring high emissions standards, this high emissions standards can only pay rational technique one-tenth this locality and meaningful Shangdi is observed by gas-firing economically, therefore also can be the subject matter of an invention be discussed in further detail below.

No matter it whether be duel fuel engine, the hybrid type of simple gas engine or the motor driven as gasoline, diesel oil or heavy oil with liquid fuel or above-mentioned engine type, before waste gas is disposed to environment, all inevitably utilize suitable equipment and method to purify or this waste gas of pretreatment in the future.

Especially in order to reduce nitrogen oxide in waste gas and known employing waste gas reaction device and especially so-called " SCR reactor ".

Term " SCR " is the abbreviation of English " SelectiveCatalyticReduction (selective catalytic reduction) " at this and can be called as in spoken language " catalyst converter ", and it reduces the nitrogen oxide in waste gas.If it is not just working in SCR reactor as in such as with the automobile of platinum catalysis equipment material, then catalyst converter element is such as formed by pottery or metal and is had specific reaction coating.But reduction reaction and coating only appear at waste gas when mixing with suitable chemical substance such as urea or ammonia in advance relatively, and described chemical substance must evaporate ammonification in the offgas.

In order to described mixing and evaporation, be aware of from prior art, before entering SCR reactor, the certain length of mixing section formed as mixing evaporating pipe is given for reactive material mixing and evaporation as urea and waste gas.In order to ensure mixing reliably and evaporation, this mixing section is arranged with the mixed pipe line form with certain minimum length between waste gas header and SCR reactor so far.But because mixed pipe line in the solution known from prior art as following go back composition graphs 2 illustrate as described in extend from motor, therefore in hull, occupy very large structure space from the mixed pipe line of the known big-block engine of prior art, be therefore an impediment to compact structure.

But, be not the valuable structure space only having such a mixed pipe line requested number considerable.Usually exactly there is multiple cylinder sleeve, as 6,8,10,12 or even 14 cylinder sleeves large-sized diesel motor in need to arrange two or even more than the supercharging group with turbosupercharger of two, replace an only supercharging group, here, arrange separately for each turbosupercharging the whole device be made up of mixed pipe line and waste gas reaction device in the prior art so far, this naturally determines the extra of structure space and takies in a large number.

Illustrate the problems referred to above in conjunction with schematic diagram 2, Fig. 2 shows from the known large-sized diesel motor comprising waste gas header, mixed pipe line, SCR reactor and supercharging group of prior art for only having when unique turbosupercharger.If be provided with multiple turbosupercharger, then in the prior art so far for each independent turbosupercharger isolated system of being made up of mixed pipe line and SCR reactor of relative set one respectively.Here, at this, consider for place and abandon this view with multiple turbosupercharger, especially because for technician, from Fig. 2, arbitrarily obtaining the overall arrangement with multiple turbosupercharger.

Fig. 2 illustrates a kind of known large-scale diesel engine 1 ', and it has waste gas header 4 ' and in supplying waste gas 5 ' such as at the mixing section 12 ' of this mixed pipe line 121 ' form mixed with urea, urea is evaporated into ammonia in waste gas 5 '.As mentioned above, in order to mix and evaporation with the reliable of waste gas 5 ' entering urea before SCR reactor 6 ' as shown in the figure, must ensure the mixing section 12 ' in mixing evaporating pipe form with so that the specific minimum length of mixed pipe line 121 '.In order to the minimum length of the mixed pipe line 121 ' between waste gas header 4 ' and SCR reactor 6 ' can be observed, known from prior art according in the large-sized diesel motor of Fig. 2, mixed pipe line 121 ' first extends from motor via link 122 ', thus has the space being enough to be used in observing required mixed pipe line 121 ' minimum length.

Without the need to also can directly see from schematic diagram 2 with further illustrating, really by this structure ensure that urea reliable evaporation and with the mixing of waste gas 5 ' entering mixed pipe line 121 ' from waste gas header 4 '.This structure needs not acceptable large space but then, this large space especially in hull be cannot provide or can by more good utilisation in other side.

In addition, this structure also has other debatable performance that such as technician finds at once.That is, an important known problem own is vibrated exactly, and this vibration is introduced into surrounding environment and is equiped with in the constituent elements of installation of this motor usually can having in up to the operation even more than the monoster engine of 10000KW power/cylinder.In addition, current known marine engine such as has nearly 12 cylinders or even 40 cylinders usually, so strong vibration can be introduced hull and especially also introduce parts such as waste gas system, catalyst system and the turbo-charger sytem with supercharging group installed on the engine by described cylinder in running state, as a result, do not specifying that in suitable counter-measure is as vibration compensation device situation, they may be badly damaged or even be out of order.But in this floating structure of the SCR catalyst system according to Fig. 2, known vibration compensation device is also no longer enough to prevent this structural damage for a long time usually.

But, additional line part and associated such as also bring other passive technique effect through being also not desirable just as the longer waste gas streams path being such as arranged on mixed pipe line 121 ' and SCR reactor 6 ' and the link 122 ' between SCR reactor 6 ' and supercharging group 71 ' or other tube-carrier fitting in the large-scale diesel engine of Fig. 2 except undesirable material consumption, the temperature of the waste gas 5 ' such as in pipe-line system and/or pressure drop, this eventually reduces turbo power and brings and naturally undesirable and that thus will as far as possible be avoided a series of other passive technique influence known for technician itself thereupon.

Summary of the invention

Therefore, in view of this prior art, task of the present invention be propose a kind of improvement motor and especially there is the crosshead type large diesel engine of exhaust gas catalyzer system especially SCR reactor, at this, avoided and especially obtained saving local waste gas system layout and the shortening of the flow-path-length between the outlet valve at cylinder sleeve and the supercharging group with turbosupercharger from the shortcoming that prior art is known as far as possible.Another task of the present invention is to provide a kind of internal-combustion piston engine especially large-sized two-stroke diesel engine, can save motor fuel whereby and totally can reduce toxic emission under similar load condition.

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 cylinder block of multiple cylinder sleeve, each cylinder block has a firing chamber and each self-corresponding outlet valve, wherein, so flow with same waste gas header and be communicated with in each firing chamber of the cylinder block of described cylinder sleeve, namely in running state, waste gas can be supplied to this waste gas header from each firing chamber of the cylinder block of described cylinder sleeve via each self-corresponding outlet valve.In addition, in order to process, waste gas can be admitted to waste gas reaction device from waste gas header in purification runs.In addition, be provided with the supercharging device for air compressing, waste gas from waste gas reaction device can be supplied to supercharging device in purification runs, thus makes one or more cylinder sleeves that can be supplied to one or more cylinder sleeve and/or this cylinder block by supercharging device by the air compressed via each self-corresponding scavenging air opening as scavenging air.In addition, this waste gas header carries by the guiding element in guide tank form and is fixed on internal-combustion piston engine.According to the present invention, this guide tank is so formed as bypass section, that is, waste gas can be supplied to this supercharging device when walking around waste gas reaction device via this guide tank in by-pass operation.

Therefore, for the present invention importantly, the guide tank of carrying waste gas header so forms as bypass section and arranges, that is, waste gas can be supplied to this supercharging device via this guide tank walking around in waste gas reaction device situation in by-pass operation.

Not definitely required but for practice very advantageously, this guide tank flows with waste gas distribution circuit and is communicated with, this waste gas distribution circuit is especially preferably so close to cylinder sleeve and is arranged in the region between supercharging device and waste gas header with being basically parallel to I. C. engine crankshaft, that is, waste gas can be supplied to supercharging device from this waste gas reaction device via this waste gas distribution circuit.In brief, between waste gas header and one or more exhaust-gas turbochargers of supercharging device, be particularly preferably provided with waste gas distribution circuit, the waste gas from waste gas reaction device and/or guide tank is distributed to turbosupercharger by waste gas distribution circuit.Thus, effectively can realize at big-block engine first and also the treated waste gas from same waste gas reaction device can be distributed to multiple exhaust-gas turbocharger in especially longitudinally scavenged formula large-sized two-stroke diesel engine simultaneously.

Be different from and (from the known motor of prior art wherein need not arranging separately in by self general arrangement situation that mixed pipe line and waste gas reaction device are formed and separately at least one oneself waste gas reaction device must be set to each turbosupercharger so far, which results in and above-mentioned additionally take structure space in a large number), by the present invention and in conjunction with waste gas distribution circuit, first time can realize especially for having multiple cylinder sleeve such as 6, 8, 10, 12 or the large-scale diesel engine of even 14 cylinder sleeves (each compress cell of cylinder sleeve has at least two supercharging groups, the each personal exhaust-gas turbocharger of described supercharging group drives), unique waste gas reaction device is only set or unique device be made up of mixed pipe line and waste gas reaction device is only set, treated waste gas is subsequently from being assigned to each supercharging group here.

In addition, in motor of the present invention, obviously also especially for the motor with multiple cylinder sleeve, at least two waste gas reaction devices or at least two devices be made up of mixed pipe line and waste gas reaction device can be such as set for certain consideration in particular situations, at this, one of them described waste gas reaction device or one of them described device be made up of with waste gas reaction device mixed pipe line flow with a waste gas distribution circuit respectively and are communicated with, by this waste gas distribution circuit, waste gas can be assigned at least two supercharging groups from same waste gas reaction device.

Therefore, by the present invention, first time not only saves lower profuse structure space whereby, because by guide tank of the present invention, waste gas, not occurring or not needing can directly transfer to this turbosupercharger from waste gas header via guide tank in the by-pass operation of waste-gas cleaning, can save unwanted connecting tube thus.

On the other hand, with the guide tank of the present invention with waste gas distribution circuit in combination, the quantity of the quantity of waste gas reaction device or the device be made up of mixed pipe line and waste gas reaction device can be reduced to bare minimum, here, under most vantage, only a waste gas reaction device or a device be made up of mixed pipe line and waste gas reaction device also need be set.Therefore, by means of only utilize guide tank as bypass section very compactly according to the present invention and preferably and guide tank and with turbosupercharger supercharging device between waste gas distribution circuit in combination, just can save structure space considerablely.

But in addition also simultaneously by the invention solves other the problems referred to above a series of known from prior art.

Therefore, in a device in accordance with the invention, obviously alleviate the problems referred to above be attended by by running the vibration that motor causes, this finally especially determined by compact structure.Therefore, pass through the present invention, the impaired danger of the waste gas system that caused by caused vibration is significantly reduced based on the compact Layout form of whole waste gas system and compact structure by structures shape, this waste gas system comprises waste gas header, perhaps with the waste gas reaction device of mixed pipe line, with turbo charge system and the waste gas distribution circuit of supercharging group, thus usually without the need to taking addition thereto to reduce the vibration of vibration in the constituent elements of waste gas system whole waste gas system in other words in motor of the present invention, automatically accomplished by structures shape ground because this can say.

The compact Layout of waste gas system of the present invention and structure especially also bring other good effect, that is, no longer need and thus can save the above-mentioned additional line part in waste gas system.Thus, know from prior art and naturally undesirable longer exhaust flow path is avoided by the present invention.Therefore, not only save the material of the additional line part for no longer needing, and reliably avoid the technique effect of other passiveness caused by the path of the unnecessary length in the waste gas system disclosed in prior art.Therefore, the temperature such as substantially reducing the waste gas in waste gas system reduces and/or pressure reduction, which increase the power of turbosupercharger, thus one, finally such as under similar load condition, also motor fuel can be saved, and decrease toxic emission generally, this finally also has good effect to environment.

In addition, the disappearance of additional line part also further improves vibration behavior, because owing to there is no additional line part, the structure of described waste gas system and arrange overall compacter and final from vibrotechnique rigidity more, therefore, caused vibration better can be compensated or can be can't help waste gas system or its constituent elements first time completely and be born, and then also reduces impaired Potential feasibility further.

For putting into practice in a particularly preferred embodiment, the bypass section of guide tank guide tank in other words comprises bypass valve, thus the waste gas streams from waste gas header can be walked around in waste gas reaction device situation by relieving and can by corresponding locking in purification runs in by-pass operation.

For putting into practice in an embodiment of particular importance, internal-combustion piston engine is big-block engine and especially longitudinally scavenged formula large-sized two-stroke diesel engine and comprise above-mentioned waste gas distribution circuit, waste gas distribution circuit is preferably so basically parallel to I. C. engine crankshaft ground and extends about in the vertical region between waste gas header and bent axle of internal-combustion piston engine on the other hand near supercharging device (advantageously comprising at least one first supercharging group and the second supercharging group) on the one hand, thus waste gas can be supplied to the first supercharging group and/or the second supercharging group via this waste gas distribution circuit.

Therefore, this waste gas distribution circuit is advantageously more or less close to waste gas header positioned beneath on guide tank and near cylinder sleeve described in one of them.

Thus one, especially the air inlet pipeline to the exhaust-gas turbocharger of supercharging group is obviously shortened and is saved important place, described important place subsequently such as can for power operation platform and maintenance work or other operation, and on power operation platform, such as miantainers and other personnel can move on the engine.In addition, the pressure loss is at least partially avoided by the pipeline shortened, and also actively have influence on the natural frequency of waste gas system and the natural frequency of especially waste gas header, thus one, can material be saved for these constituent elementss and only just reduce cost thus.

In addition, the length of waste gas distribution circuit preferably can so be shortened about waste gas header in all embodiments of the invention, namely, waste gas distribution circuit just can also flow with all corresponding exhaust-gas turbochargers and be communicated with, but is no more than the border of the device be made up of turbosupercharger in other its length of place.

According to the project organization of waste gas system, in practice except waste gas header and waste gas distribution circuit, can also so arrange and arrange and be used for mixing with waste gas and evaporating reactive material, as the mixing section of urea, namely, waste gas can be supplied to waste gas reaction device via this mixing section, here, this mixing section specifically can be arranged with the mixed pipe line form between waste gas header and waste gas reaction device, therefore, waste gas can by the evaporation of reactive material in mixing section and mix with waste gas subsequently in waste gas reaction device by reliable treatments.

In addition, in one particular embodiment of the present invention, this mixing section can be integrated in waste gas header and/or waste gas header itself can be formed as mixing section at least partly but preferably fully.Thus, obviously also save valuable place further and final also can minimum material consumption and cost further.

In another embodiment also it is possible that this mixing section at least partly but be preferably integrated in fully in waste gas reaction device, or obviously also it is possible that this waste gas reaction device and this waste gas distribution circuit form a common integral component.

In addition, described waste gas header, mixing section and waste gas reaction device, alternatively even together with waste gas distribution circuit, especially can be formed with a common integral component form, this integral component preferably in the mode being arranged essentially parallel to the bent axle of internal-combustion engine on the one hand near the first supercharging group and the second supercharging group with extend in the region of cylinder sleeve on the other hand.

Obviously in practice commonly, this waste gas reaction device need not run for a long time, such as when the ship's navigation with motor of the present invention is in certain region that there is not corresponding strict waste gas regulation, therefore, such as economically set out or maybe advantageously temporarily do not make the work of waste gas reaction device in order to maintenance work, way is that this waste gas is walking around via guide tank the turbosupercharger being supplied to supercharging device in waste gas reaction device situation.

In order to optimize waste gas streams further, also can advantageously also arrange in waste gas system except the bypass section in guide tank and other bypass line one or more is set, make waste gas can be supplied to waste gas distribution circuit in waste gas reaction device situation to guide to corresponding supercharging group or turbosupercharger further walking around, namely, waste gas can walk around waste gas reaction device via bypass line, thus waste gas no longer flows through waste gas reaction device.For this reason, other bypass line described such as can be arranged between waste gas header and waste gas distribution circuit.

Other bypass line described itself such as can be arranged through bypass valve locking, although other bypass line wherein said itself not necessarily advantageously can be formed as bypass valve depending on mode of execution.In other words, this bypass valve plays bypass line effect, and this may be especially favourable when such as waste gas distribution circuit next-door neighbour waste gas header is such as preferably directly arranged with it abreast contiguously.

In addition, obviously this waste gas header also can by waste gas header valve by locking like this, that is, when waste-gas cleaning or waste gas treatment do not need as mentioned above (especially in by-pass operation), waste gas cannot be supplied to waste gas reaction device from waste gas header again in such running state.For this object, waste gas distribution circuit also can by waste gas distributing valve by locking like this, that is, waste gas cannot be supplied to this waste gas distribution circuit from waste gas reaction device again.

In another embodiment of the present invention, described waste gas header so can comprise the first accumulation chamber of waste gas and flow the second accumulation chamber of waste gas be communicated with the first accumulation chamber of waste gas, namely, waste gas can only be voltages v+and v-are supplied directly to described first accumulation chamber of waste gas from first group of cylinder sleeve, and waste gas can only be voltages v+and v-are supplied directly to described second accumulation chamber of waste gas from second group of cylinder sleeve, wherein between the first accumulation chamber of waste gas and the second accumulation chamber of waste gas, especially preferably compensating part is set, for compensating mechanical and/or that heat causes stress and/or strain.

Thus, such as can not only compensate thermal strain better or also have the mechanical stress of other form such as to vibrate, and the distribution of the waste gas streams in waste gas header can be optimized thus, and can at least substantially stop or minimize the influencing each other of waste gas streams from the variant cylinder sleeve being connected to waste gas header simultaneously.

Completely similarly, this waste gas distribution circuit also can comprise the first waste gas distributor chamber and be communicated with flow the second waste gas distributor chamber of being communicated with and so flowing with this waste gas header of the first waste gas distributor chamber, namely, waste gas can only be voltages v+and v-are supplied directly to the first waste gas distributor chamber from waste gas header via the first bypass line or the first bypass valve, and waste gas can only be voltages v+and v-are supplied directly to the second accumulation chamber of waste gas from waste gas header via the second bypass line or the second bypass valve, wherein, such as the first bypass valve and/or the second bypass valve can be realized by the bypass valve of described guide tank.

In a particularly preferred modification of previous embodiment of the present invention, waste gas is only voltages v+and v-are supplied directly to the first waste gas distributor chamber from the first accumulation chamber of waste gas of waste gas header via the first bypass line or the first bypass valve, and waste gas is only voltages v+and v-are supplied directly to the second accumulation chamber of waste gas from the second accumulation chamber of waste gas of waste gas header via the second bypass line or the second bypass valve, wherein, such as the first bypass valve and/or the second bypass valve can be realized by the bypass valve of described guide tank.

In addition, in each corresponding embodiment, can be advantageously provided between the first waste gas distributor chamber and the second waste gas distributor chamber and compensate bindiny mechanism, for compensating mechanical and/or that heat causes stress and/or strain, thus the mechanical stress that such as can not only compensate thermal strain or other type better is such as vibrated, the distribution of the waste gas streams in waste gas distribution circuit also can be optimized thus and the influencing each other of waste gas streams at least substantially preventing or minimize from the variant waste gas header bypass line being connected to distribution circuit simultaneously.

Obviously, this bypass valve and especially the bypass valve of guide tank and/or the first bypass valve and/or the second bypass valve and/or waste gas header valve and/or waste gas distributing valve also can be controlled or adjustable, especially with electronic or hydraulic pressure or air pressure mode, be particularly advantageously controlled or adjustable by computerized equipment according to predeterminable internal-combustion piston engine running parameter.

To this, particularly also possible that, according to known mode itself, sensor and especially Abgassensor, temperature transducer, pressure transducer or other suitable sensor are suitably arranged for controlling or regulating described bypass valve and the especially bypass valve of guide tank and/or the first bypass valve and/or the second bypass valve and/or waste gas header valve and/or waste gas distributing valve.

In order to optimize exhaust-gas flow further, waste gas header and especially the first accumulation chamber of waste gas and/or the second accumulation chamber of waste gas can comprise guiding mechanism and especially guide plate, for guiding in waste gas header and distributing described waste gas, be particularly useful for the different portions section described waste gas being distributed to waste gas distribution circuit, distribute to the first waste gas distributor chamber and the second waste gas distributor chamber of waste gas distribution circuit specifically.

Completely similarly and object similarly, this waste gas distribution circuit and especially the first waste gas distributor chamber and/or the second waste gas distributor chamber can certainly comprise steering equipment and especially deflecting plate, for turning in waste gas distribution circuit and distributing described waste gas, be particularly useful for the different exhaust-gas turbocharger described waste gas being distributed to this supercharging device, especially the first supercharging group and the second supercharging group of supercharging device is distributed to, controlled or adjustable gate can be provided with at this, thus make gas flow regulate by this gate or control.

In order to fixing, described waste gas header and waste gas distribution circuit are especially preferably, but not necessarily always carried by same guiding element and/or guide, here, this guiding element advantageously guide plate, but perhaps also can be additional guide tank or other suitable guide mechanism or fixed mechanism for the fixing of described waste gas header and waste gas distribution circuit and guide.

In addition, this guiding element very advantageously so forms in practice and this waste gas header and waste gas distribution circuit are so placed on this guiding element, that is, machinery and/or stress that heat causes and/or strain or also have the vibration of waste gas header and waste gas distribution circuit or other machine part to be compensated at least partly.
