Specific embodiment
Fig. 1 shows internal-combustion engine system 1, has in the subsequent turbocharger 4 of exhaust gas receiver 3.4 He of turbocharger
Exhaust gas receiver 3 is arranged on the top platform at 2 top of engine, so that being connect in the exhaust gas that engine head sprays by exhaust gas
The multiple exhaust gas entrances 26 received in the receiver shell 14 of device 3 are ejected into exhaust gas receiver 3.Exhaust gas receiver 3 is also and by void
NO shown in linexReduction unit 5 fluidly connects.When needing to purify exhaust gas, by pipeline (shown by dashed lines) by exhaust gas from useless
Gas receiver 3 is guided to NOxReduction unit 5, and from NOxReduction unit 5 is guided to turbocharger 4.Mould is run in another kind
Under formula, directly exhaust gas is guided from exhaust gas receiver 3 to turbocharger 4.
In another operational mode, the exhaust gas from exhaust gas receiver 3 is divided into two individually streams, so that a stream
Turbocharger 4 is direct supplied to, another stream is directed to NO before being directed to turbocharger 4xReduction unit 5.
Usually needing NOxThe operational mode is applied when the specific temperature of reduction unit 5, because the exhaust gas of heat guarantees to maintain NOxReduction is single
The temperature of member 5.
In Fig. 2, exclusively for the purposes of illustration, a part of receiver shell 14 of exhaust gas receiver 3 is removed, with
Showing internal-combustion engine system 1 includes guide device 6, which controls the flowing of exhaust gas in the first operational mode, so that
Exhaust gas is channeled directly into turbocharger 4, and exhaust gas is being directed to turbocharging by control in second of operational mode
NO is conducted through before device 4xReduction unit 5.Guide device 6 include with exhaust gas receiver 3 be in fluid communication first entrance 7,
With NOxThe second entrance 8 and the outlet 9 being in fluid communication with turbocharger 4 that reduction unit 5 is in fluid communication.Guide device 6 is also wrapped
Include connection first entrance 7, second entrance 8 and the piping unit 12 for exporting 9.Guide device further includes by-passing valve 10 and the first reaction
Valve 16, the by-passing valve 10 have a valve components 11 for closing and opening first entrance 7, which is arranged to and the
Two entrances 8 are in fluid communication, to control exhaust gas from NOxAccess of the reduction unit 5 to guide device 6.Internal-combustion engine system 1 further includes
Two reactive valves 17 are arranged to be in fluid communication with the hole 18 in receiver shell 14, to allow exhaust gas to lead to NOxReduction unit 5.
In the first operational mode, when exhaust gas is directly directed to turbocharger 4, by-passing valve 10 is opened, and first is anti-
Valve 16 and the second reactive valve 17 is answered to close.In this way, NO has been bypassedxReduction unit 5.In the second operational mode, bypass
Valve 10 is closed, and the first reactive valve 16 and the second reactive valve 17 are opened, so that exhaust gas is drawn by the hole 18 in receiver shell 14
It is directed at NOxThen reduction unit 5 is directed to piping unit 12 by second entrance 8, and increases from the guidance of outlet 9 to turbine
Depressor 4.It can be seen that (i.e. major part means to be greater than the major part of first entrance 7, valve components 11 and piping unit 12
The 50% of piping unit) it is arranged in receiver shell 14.Therefore, the major part of guide device 6 is arranged in exhaust gas receiver 3
Inside, the space needed for minimizing on platform, which reduce the gross spaces needed on ship.
Therefore, by by by-passing valve 10 and the piping unit 12 for being used to connect exhaust gas receiver 14 and turbocharger 4
Entirely or at least major part is integrated in exhaust gas receiver 3, internal-combustion engine system 1 occupy gross space substantially reduce/substantially
It minimizes.Exhaust gas receiver 3 increases, so that the volume of exhaust gas receiver 3 is identical, but can be by extending exhaust gas receiver 3
Realize this expansion, this, which not will lead to, needs more spaces with around the exhaust gas receiver 3, because engine 2 is still on platform
It is so more slightly longer than exhaust gas receiver 3.
In addition, by the inside that the major part of by-passing valve 10 and piping unit 12 is arranged in exhaust gas receiver 3, according to
The type of the preferred turbocharger of ship builder, it is only necessary to design the position of outlet.Therefore, a kind of that there is radial inlet type whirlpool
The position for taking turns the outlet 9 in the engine design of booster 4 must when carrying out another axial entrance type turbocharger design

End.Second pipe part 34 has first end, and second entrance 8 is arranged in the first end.First pipe part 33 and second pipe
Part 34 connects into formation angle A in-between (shown in Fig. 3).First pipe part 33 and second pipe part 34 pass through connection
Part 35 connects, and connector 35 is arranged in inside receiver shell 14.
By-passing valve 10 includes the control unit 15 for controlling valve components 11 to open or close first entrance 7, in Fig. 2
In, control unit 15 is at least partially disposed at the outside of receiver shell 14.Therefore, receiver shell 14 is open with third
27, to provide access, allows the control unit 15 of by-passing valve 10 to be arranged in the outside of exhaust gas receiver 3, controlled
Valve components 11 are arranged in the inside of exhaust gas receiver 3.
In Fig. 1, the second entrance 8 of the first reactive valve 16 operation is arranged in the outside of receiver shell 14, but another
In embodiment, second entrance 8 can be arranged in inside, so that only the first reactive valve 16 passes through first in receiver shell 14
Opening 23 extends on the outside of receiver shell 14.Internal-combustion engine system 1 further includes the second reactive valve 17, is arranged to and receives
Hole 18 in device shell 14 is in fluid communication, to allow exhaust gas to lead to NOxReduction unit 5.In order to guarantee completely around NOxReduction is single
Member 5, the second reactive valve 17 are closed.First reactive valve 16 especially throttles between 2 starting period of engine.
The outlet 9 of guide device 6 is arranged in the upstream of turbocharger 4, in Fig. 1, is arranged in receiver shell 14
Second opening 24 in, to provide fluid communication between the outlet of guide device 69 and turbocharger 4.Therefore, 9 cloth are exported
It sets in the inside of receiver shell 14.Piping unit 12 also extends to except the second opening 24 of receiver shell 14, from
And export 9 outsides for being arranged in receiver shell 14.In Fig. 1, the outlet 9 of guide device 6 is axial about receiver shell 14
Arrangement, guide device 6 are fluidly connected to turbocharging via the pipeline 31 of the radial turbine entrance 32A by turbocharger 4
Device.In Fig. 3, the outlet 9 of guide device 6 is about the radial arrangement of receiver shell 14, and guide device 6 is via passing through turbocharging
