The engine is preferably a two-stroke engine or a two-stroke crosshead engine. The engine can be a diesel engine or a gas engine, a dual fuel engine or a multi-fuel engine. Such engines can burn liquid or gaseous fuel and can be self-igniting or forced-igniting.
[0003] The internal combustion engine can be a longitudinally flushed two-stroke engine.
[0004] The term "internal combustion engine" also refers to large engines which can not only be operated in diesel mode, which is characterized by self-ignition of the fuel, but also in Otto mode, which is characterized by positive ignition of the fuel, or in a hybrid mode of the two modes. Furthermore, the term "internal combustion engine" includes, inter alia, dual-fuel engines and large engines in which self-ignition of the fuel is used for positive ignition of another fuel.
[0005] The engine speed is preferably below 800 RPM, in particular for four-stroke engines; more preferably below 200 RPM, in particular for two-stroke engines, which indicates that the engine belongs to the group of low-speed engines.
[0006] The fuel can be diesel or marine diesel or heavy fuel oil or emulsions or slurries or methanol or ethanol, as well as gases such as liquefied natural gas (LNG), liquefied petroleum gas (LPG).
[0007] Other possible fuels which can be added on request are: LBG (liquefied biogas), biofuels (e.g. oil made from algae or seaweed), ammonia, hydrogen, carbon dioxide synthetic fuels (e.g. fuels made by electricity-to-gas or electricity-to-liquid technologies).
[0008] Large ships, in particular cargo ships, are usually powered by internal combustion engines, in particular diesel and / or gas engines, mostly two-stroke crosshead engines.
[0009] The exhaust receiver can be fluidically connected to a turbocharger and at the same time also to some kind of aftertreatment device.
[0010] All the piping and valves of such fluidic connections take up space and need to be customized for each engine system depending on the turbocharger used and the arrangement of the turbocharger and the aftertreatment device.

X The flow from the restoration unit to the guiding device is restored. The main parts of the first inlet, valve elements, and piping unit are arranged in the receiver housing.
[0012] By incorporating the bypass valve and the main part of the piping unit connecting the exhaust gas receiver to the turbocharger into the exhaust gas receiver, the overall space occupied by the internal combustion engine system can be significantly reduced. However, manufacturing, modifying, and / or maintaining such an engine system may require complex interventions, which can increase the workload and costs for engine designers / manufacturers.
[0013] The objective of this invention is to provide an exhaust gas receiver and an internal combustion engine to overcome the shortcomings of the prior art, especially to achieve convenient operation, compact structure and high stability.
[0014] This objective is achieved through the characteristics of the independent claims.
[0015] According to the present invention, the exhaust gas receiver is an exhaust gas receiver for an internal combustion engine system.
[0016] The internal combustion engine includes at least one cylinder that produces exhaust gases, a turbocharger, and NO. X The internal combustion engine of the reduction unit.
[0017] According to the present invention, the exhaust gas receiver includes a receiver housing for receiving exhaust gas.
[0018] The receiver housing of the exhaust gas receiver is used to receive exhaust gas from at least one cylinder. Fluctuating pressures from different cylinders can be balanced. The receiver housing has a longitudinal axis. The receiver housing is typically cylindrical and preferably includes at least one exhaust inlet, which is fluidly connected to or can be connected to the cylinder outlet.
[0019] The exhaust gas receiver includes a guide device. This guide device is used to control the exhaust gas before it enters the turbocharger.
[0020] The guiding device includes a first inlet for establishing fluid communication with the receiver housing. This fluid communication allows for gas flow.
[0021] The guiding device includes a function for interacting with NO.X The reduction unit establishes a second inlet for fluid communication.
[0022] The guiding device also includes an outlet for establishing fluid communication with the turbocharger.
[0023] The guiding device also includes a first piping unit connecting the first inlet, the second inlet, and the outlet.
[0024] Therefore, exhaust gas can enter through the first inlet (and thus from the receiver housing) and / or the second inlet (and thus from the NO). X The flow from the reduction unit to the outlet (and thus to the turbocharger).
[0025] A first inlet may be arranged in a first pipe, and / or a second inlet may be arranged in a second pipe, wherein the first pipe and / or the second pipe are in fluid communication with a first piping unit. The first pipe and / or the second pipe may be connected to the first piping unit.
[0026] Alternatively, the first inlet and / or the second inlet may be located directly in the first piping unit.
[0027] The exhaust gas receiver includes a function for NO X A second piping unit is provided to establish fluid communication between the reduction unit and the second inlet, and the second piping unit is arranged at least partially in the receiver housing.
[0028] Preferably, the guide device and receiver housing, the guide device and second piping unit, and / or the receiver housing and second piping unit are each directly connected to each other. In the context of this application, direct connections between the guide device and the second piping unit, between the guide device and the receiver housing, and / or between the second piping unit and the receiver housing imply a fixed connection without any compensating elements. Direct connections may include valves or pipes.
[0029] Advantageously, a stable unit is formed by the guiding device and the receiver housing, and preferably also by a second conduit unit.
[0030] Since the receiver housing is typically fixedly attached to the engine frame, changes in pressure and temperature do not cause the guide device to vibrate violently.
[0031] Meanwhile, the guidance device and receiver housing form a compact unit that does not take up too much space in the engine compartment.
[0032] When installed in an internal combustion engine system, the guide device is preferably located below the receiver housing.
[0033] The guiding device may include a bypass valve for closing and opening the first inlet.

[0036] Bypass valves are easy to operate, install, maintain, and replace.
[0037] The guiding device may also include a first reactor valve for closing and opening the second inlet.
[0038] The first reactor valve is preferably located downstream of the second piping unit and / or upstream of the second inlet, and may be located between the second piping unit and the second inlet. Since at least a portion of the second piping unit is located within the receiver housing, the first reactor valve may also be located between the receiver housing and the second inlet. Preferably, the first reactor valve is not located within the receiver housing. Similar to a bypass valve, the first reactor valve facilitates operation, installation, maintenance, and replacement.
[0039] The first reactor valve may optionally be located in the second piping unit, the second inlet, or the second pipe.

In this case, the axis of the inlet pipe portion and the axis of the outlet pipe portion can be at a 90° angle.
[0055] In this case, for example, when the inlet pipe portion enters the cylinder jacket of the receiver housing in the first radial direction, and the outlet pipe portion leaves the cylinder jacket of the receiver housing in the second radial direction, the axis of the inlet pipe portion and the axis of the outlet pipe portion can also be at an angle of 90°, wherein the first radial direction and the second radial direction are at an angle of 90°.
[0056] The cross conduit section can extend through the longitudinal axis of the receiver housing. The cross conduit section can extend partially along the longitudinal axis, or it can intersect the axis at a 90° angle. The cross conduit section can pass through the middle of the receiver housing, providing a symmetrical and stable arrangement.
[0057] The second piping unit, particularly the inlet piping section as described above, may include a first compensation element. This compensation element can absorb NO from the receiver housing. X This compensates for any vibrations or expansions between the units caused by temperature or pressure changes.

This compensating element can absorb any vibrations or expansions in the turbocharger caused by temperature or pressure variations. The second compensating element can decouple vibrations and variations along the piping length from the guide and receiver housings.
[0061] Alternatively, the first piping unit may be connected to or may be connected to a second compensating element disposed between the first piping unit and the turbocharger.
[0062] Preferably, the second compensation element can compensate for length changes of 0.5cm-20cm, and more preferably 1cm-10cm.
[0063] Typically, the receiver housing may include a housing outlet for connecting to the NO via an outlet pipe connected to the housing outlet. X The reduction unit establishes fluid communication. Exhaust gas can be guided from the receiver housing to the NO₂ zone through the housing outlet and outlet pipe. X Restoration unit.
[0064] A second reactor valve for closing and opening the shell outlet can be arranged in the shell outlet or outlet pipe.

[0066] Exhaust gas can be guided to NO through the outlet. X The reduction unit, and / or the material is directly guided to the turbocharger via the first inlet of the guide device.
[0067] The exhaust gas receiver may include a third compensation element disposed downstream of the housing outlet.
[0068] The third compensation element can absorb NO. XThis compensates for any vibrations or expansions caused by temperature or pressure changes within the unit. A third compensation element decouples vibrations and changes along the piping length from the receiver housing.
[0069] Alternatively, the housing outlet or housing tube can be connected to the downstream of the receiver housing and the NO. X The third compensation element upstream of the restoration unit.
[0070] Preferably, the third compensation element can compensate for length changes of 0.5cm-20cm, and more preferably 1cm-10cm.

X Between the restoration units.
[0075] The internal combustion engine system may include a flexible connector that connects the receiver housing and / or guide device to the engine frame.
[0076] The first piping unit can be installed onto a flexible connector. This flexible connector can compensate for vibrations caused by the turbocharger.
[0077] Turbochargers can be mounted on the drive end of an internal combustion engine system.
