Description

本発明は、請求項１のおいて書き部分に記載の内燃機関のためのガス供給装置に関するものである。それに加え本発明は、請求項９のおいて書き部分に記載の、内燃機関で燃焼可能な自然発生ボイルオフガス（NBOG）と強制的に蒸発させて発生させたボイルオフガス（FBOG）の混合ガスを調達する方法にも関するものである。   The present invention relates to a gas supply device for an internal combustion engine according to claim 1. In addition, the present invention provides a mixed gas of a naturally generated boil-off gas (NBOG) combustible in an internal combustion engine and a boil-off gas (FBOG) generated by forcibly evaporating, as described in claim 9. It also relates to the procurement method.

燃料としての天然ガスを貯留するガスタンカーやその他の乗り物において天然ガスは液化された状態（液化天然ガス）で輸送され、その際冷却され液化された天然ガスの温度はおよそ−１６２℃で、その圧力はおよそ大気圧に保たれている。輸送されるべき冷却され液化された天然ガスを収容するために使用されるガス容器もしくは貯蔵タンクは、断熱に費用がかかる。それでもなお、輸送される天然ガスがある程度温まってしまうのは避けられず、冷却され液化された天然ガスを貯留するガス容器においては、容器内部の温度上昇によって天然ガスがいわゆるNBOGとして蒸発する。冷却され液化された天然ガスを貯留するガス容器内部のこのような避けられない蒸発の結果として生じる圧力の上昇に抵抗するために、ガス容器からNBOGが取り除かれる。冷却され液化された天然ガス用の貯蔵タンクを有する固定されたガスで駆動する駆動装置にも同じ原則が当てはまる。   In gas tankers and other vehicles that store natural gas as fuel, natural gas is transported in a liquefied state (liquefied natural gas), and the temperature of the cooled and liquefied natural gas is about −162 ° C. The pressure is maintained at about atmospheric pressure. Gas containers or storage tanks used to contain the cooled and liquefied natural gas to be transported are expensive to insulate. Nevertheless, it is inevitable that the natural gas to be transported is heated to some extent, and in a gas container that stores the cooled and liquefied natural gas, the natural gas evaporates as so-called NBOG due to the temperature rise inside the container. NBOG is removed from the gas container to resist the pressure increase that occurs as a result of such inevitable evaporation inside the gas container that stores the cooled and liquefied natural gas. The same principle applies to fixed gas driven drives with storage tanks for cooled and liquefied natural gas.

冷却され液化された天然ガスを貯留する貯蔵タンク内において温度上昇により蒸発した天然ガス、すなわちNBOGを、ガスを燃料とする機関とりわけガスタンカーの内燃機関に供給し、それによってそのようなNBOGをガスタンカーの駆動に利用することが、特許文献１および特許文献２からすでに知られている。さらに、NBOGの量が不充分な場合、冷却され液化された天然ガスを貯留するガス容器から液化天然ガスを取り出すことができ、蒸発器に供給可能であることも、この従来技術からすでに知られている。   Supplying natural gas, i.e., NBOG, evaporating due to temperature rise in a storage tank that stores cooled and liquefied natural gas to an engine that uses gas as a fuel, especially an internal combustion engine of a gas tanker. It is already known from Patent Document 1 and Patent Document 2 that it is used for driving a tanker. Furthermore, it is already known from this prior art that when the amount of NBOG is insufficient, the liquefied natural gas can be taken out from the gas container storing the cooled and liquefied natural gas and can be supplied to the evaporator. ing.

冷却され液化された天然ガスを貯留するガス容器から取り出された天然ガスは蒸発器の中で一部が蒸発し、蒸発した後はいわゆるFBOGとしてNBOGと混合可能となる。FBOGとNBOGとのこの混合ガスはその後、ガスを燃料とする機関とりわけ内燃機関による駆動部へと供給可能となる。蒸発しなかった、より高温で沸騰する天然ガスの成分は、既知の装置の中で使用されない状態で、ガス容器もしくは貯蔵タンクに戻される。   The natural gas taken out from the gas container storing the cooled and liquefied natural gas partially evaporates in the evaporator, and after evaporating, it can be mixed with NBOG as so-called FBOG. This mixed gas of FBOG and NBOG can then be supplied to an engine that uses the gas as fuel, particularly to a drive unit of an internal combustion engine. Natural gas components that have not evaporated and boil at a higher temperature are returned to the gas container or storage tank without being used in known equipment.

NBOGとFBOGとの混合ガスの組成は様々な条件によって左右されており、それゆえ変化に支配されている。しかしながらNBOGとFBOGとの混合ガスは、ある程度のアンチノック性を有する場合に限って、たとえばディーゼルガスエンジンやオットーガスエンジンといった内燃機関内で形成され、駆動装置で燃焼され得る。この混合ガスのアンチノック性を示す尺度として、混合ガスのいわゆるメタン価が考慮され得、このメタン価は、ほぼNBOGとFBOGとの混合ガス内のメタンとその他の成分との量の比率で表示される。任意に混合されたガスのメタン価は、様々な市販の機器を用いて確定されうる。   The composition of the gas mixture of NBOG and FBOG depends on various conditions and is therefore subject to change. However, the mixed gas of NBOG and FBOG can be formed in an internal combustion engine such as a diesel gas engine or an Otto gas engine and burned by a drive device only when it has a certain degree of antiknock properties. The so-called methane number of the mixed gas can be considered as a measure of the anti-knock properties of this mixed gas, and this methane number is displayed as a ratio of the amount of methane and other components in the mixed gas of NBOG and FBOG. Is done. The methane number of the arbitrarily mixed gas can be determined using a variety of commercially available equipment.

これまで知られている内燃機関のためのガス供給装置ではある範囲においては、アンチノック性に関しては充分な、NBOGとFBOGとの混合ガスが調達され得る。すなわち蒸発したガスのメタン価をあげることができる。しかしながら混合ガスはまだ最適なものとはみなされ得ない。そのため、とりわけメタン価８０以上を示すほどに最適化されたアンチノック性を備えた混合ガスを調達できるような、内燃機関駆動のためのガス供給装置が必要となる。
国際公開第２００５／０５８６９２号パンフレット 国際公開第２００５／０５８６８４号パンフレット In a certain range of gas supply devices for internal combustion engines known so far, a sufficient mixed gas of NBOG and FBOG can be procured with respect to antiknock properties. That is, the methane number of the evaporated gas can be increased. However, the gas mixture cannot yet be considered optimal. Therefore, there is a need for a gas supply device for driving an internal combustion engine that can procure a mixed gas having antiknock properties optimized to show a methane number of 80 or more.
International Publication No. 2005/058692 Pamphlet International Publication No. 2005/058684 Pamphlet

このことから本発明は、内燃機関の駆動装置のための新式のガス供給装置ならびに、内燃機関内で燃焼可能なNBOGとFBOGとの混合ガスを調達するための新式の方法を作り上げ、当該ガス供給装置によって混合物のメタン価を、少ないコストで最適に増大させることを可能とするという課題を有している。   From this, the present invention has created a new gas supply device for a drive device of an internal combustion engine and a new method for procuring a mixed gas of NBOG and FBOG combustible in the internal combustion engine. There is a problem that the apparatus can optimally increase the methane number of the mixture at a low cost.

この課題は、請求項１に記載のガス供給装置によって解決される。本発明においては、当該ガス供給装置は、蒸発したガスを、蒸発器を介して噴霧タンクへ送る第２のガス管システムを備えており、当該第２のガス管システムはさらに制御弁を介して、蒸発器から分かれた経路で液化ガスを噴霧タンクへと送る。他方で噴霧タンクは温度センサーと制御装置を備えており、この制御装置は温度センサーに従って、制御弁を通る液化ガスの流量を調節する。その結果、蒸発器から出てくる蒸発したガスの温度は、噴霧タンク内で液化ガスの噴霧によってコントロールされて低下可能となり、ガスの中で比重の大きい炭化水素を凝縮して液体の状態で噴霧タンクから排出させることができ、そして所定のメタン価のガスが噴霧タンクから内燃機関へと供給されることができる。   This problem is solved by the gas supply device according to claim 1. In this invention, the said gas supply apparatus is provided with the 2nd gas pipe system which sends the vaporized gas to a spray tank via an evaporator, The said 2nd gas pipe system is further via a control valve. The liquefied gas is sent to the spray tank through a route separated from the evaporator. On the other hand, the spray tank is provided with a temperature sensor and a control device, which adjusts the flow rate of the liquefied gas through the control valve according to the temperature sensor. As a result, the temperature of the vaporized gas coming out of the evaporator can be controlled and lowered by spraying the liquefied gas in the spray tank, and the hydrocarbon having a high specific gravity is condensed in the gas and sprayed in the liquid state. The gas can be discharged from the tank, and a gas of a predetermined methane number can be supplied from the spray tank to the internal combustion engine.

比喩的な意味では、噴霧タンク内において液化ガス（LNG）とともに蒸発ガスの噴霧を行うことは、FBOG（蒸発ガス）の洗浄と冷却とみなされ得る。   In a figurative sense, spraying evaporative gas with liquefied gas (LNG) in a spray tank can be considered as cleaning and cooling of FBOG (evaporated gas).

噴霧タンクと温度センサー、そして噴霧タンク内の温度センサーの測定値に応じて行われる液化ガス量の制御によって、内燃機関に供給される混合ガスのメタン価をコントロールして引き上げることができる。   The methane number of the mixed gas supplied to the internal combustion engine can be controlled and raised by controlling the amount of liquefied gas performed according to the measurement value of the spray tank, the temperature sensor, and the temperature sensor in the spray tank.

（所定の圧力での）ガスの温度は、噴霧タンクから出てくるガスの組成の尺度であり、またそれとともにそのガスのメタン価の尺度でもある。所定のメタン価を持ったガスすなわちメタン価が８０以上であるガスは好適に、液滴分離器や熱変換器を介して内燃機関に供給され得る。噴霧タンクと液滴分離器内で集められた縮合物は、管あるいは縮合物分離器を介して好適に再冷却熱変換器を通り再び貯蔵タンクへと送られる。このようにして、いわゆる噴霧循環が保証される。   The temperature of the gas (at a given pressure) is a measure of the composition of the gas coming out of the spray tank and is also a measure of the methane number of the gas. A gas having a predetermined methane number, that is, a gas having a methane number of 80 or more can be suitably supplied to the internal combustion engine via a droplet separator or a heat converter. The condensate collected in the spray tank and droplet separator is preferably routed through the tube or condensate separator, preferably through the recooling heat converter and back to the storage tank. In this way, so-called spray circulation is ensured.

このようにして調達されたFBOGをNBOGと混合して、アンチノック性に関して最適化された、NBOGとFBOGとの混合ガスが出来上がる。   The FBOG thus procured is mixed with NBOG, and a mixed gas of NBOG and FBOG optimized for anti-knock properties is completed.

内燃機関内で燃焼可能なNBOGとFBOGとの混合ガスの、本発明に係る調達方法は、請求項９で定義されている。   A method for procuring a mixed gas of NBOG and FBOG combustible in an internal combustion engine according to the present invention is defined in claim 9.

本発明の好適な更なる形成は、従属請求項と以下の説明によってもたらされる。本発明の実施例は図に基づいて詳述されるが、本発明はこれらの実施例に限定されるものではない。図に示されるのは、以下のとおりである。   Further preferred embodiments of the invention result from the dependent claims and the following description. Examples of the present invention will be described in detail with reference to the drawings, but the present invention is not limited to these examples. The figure shows the following.

ここで示される発明は、内燃機関のためのガス供給装置に関するもので、駆動燃料である冷却され液化された天然ガスが貯蔵タンク１７にある。   The invention shown here relates to a gas supply device for an internal combustion engine, in which a cooled and liquefied natural gas as a drive fuel is in the storage tank 17.

本発明に係るガス供給装置は、以下のように図１から図５に関連して比較的詳しく記述されており、図１から図５まではそれぞれ本発明に係るガス供給装置の様々な実施例を示している。   The gas supply apparatus according to the present invention is described in relatively detail with reference to FIGS. 1 to 5 as follows. FIGS. 1 to 5 show various embodiments of the gas supply apparatus according to the present invention. Is shown.

図１は、本発明に係る内燃機関３のガス供給装置の第１の実施例を示している。ガス供給装置は２つのガス管システム４と２２とを有している。   FIG. 1 shows a first embodiment of a gas supply device for an internal combustion engine 3 according to the present invention. The gas supply device has two gas pipe systems 4 and 22.

第１のガス管システム４を通じて、いわゆるNBOGが内燃機関３の方向へ送り込まれる。NBOGは、貯蔵タンク１７に準備されている液体状態かつ冷却された天然ガスが貯蔵タンクにおける当該液化天然ガスの温度上昇によって蒸発することで生じ、NBOGは第１のガス管システム４のガス管を通じて貯蔵タンク１７から排出される。ガス管に接続されているコンプレッサー１を通って、NBOGは内燃機関３へと供給可能となっている。コンプレッサーの配管１、１’、１”は内燃機関３の前方においてガスの圧力水準を介して制御される。   So-called NBOG is fed in the direction of the internal combustion engine 3 through the first gas pipe system 4. NBOG is caused by evaporation of the liquid and cooled natural gas prepared in the storage tank 17 due to the temperature rise of the liquefied natural gas in the storage tank, and NBOG is generated through the gas pipe of the first gas pipe system 4. It is discharged from the storage tank 17. The NBOG can be supplied to the internal combustion engine 3 through the compressor 1 connected to the gas pipe. The compressor piping 1, 1 ′, 1 ″ is controlled in front of the internal combustion engine 3 via the gas pressure level.

内燃機関３のためのNBOGの量が足りない場合は、第２のガス管システム２２によって液体状態かつ冷却された天然ガスを貯蔵タンク１７から取り出すことができ、ガス供給装置の蒸発器１２に供給できる。蒸発器１２の中で、貯蔵タンク１７から取り出された液化ガスは、その一部が蒸発可能であり、いわゆるFBOGとして、第１のガス管システム４からのNBOGと混合ポイント３１で混合され得る。   When the amount of NBOG for the internal combustion engine 3 is insufficient, natural gas cooled and cooled by the second gas pipe system 22 can be taken out from the storage tank 17 and supplied to the evaporator 12 of the gas supply device. it can. A part of the liquefied gas taken out from the storage tank 17 in the evaporator 12 can be evaporated, and can be mixed with the NBOG from the first gas pipe system 4 at the mixing point 31 as a so-called FBOG.

従って、混合ポイント３１の下流では、NBOGとFBOGとの混合ガスがあり、その混合ガスは熱変換器２の中で、特に室温になるまで温度調節可能であり、続いてエンジン３へと供給可能である。   Therefore, downstream of the mixing point 31, there is a mixed gas of NBOG and FBOG. The mixed gas can be adjusted in the heat converter 2 until it reaches room temperature, and can be subsequently supplied to the engine 3. It is.

それゆえエンジン内において、貯蔵タンク１７から蒸気として出されるよりも多くの天然ガスが必要とされる場合、第１のガス管システム４あるいは貯蔵タンク１７の圧力センサー２１によってこのことが認識され、追加の天然ガスが第２のガス管システム２２内の弁１０の制御によって蒸発器１２に供給される。ガス管システム２２においては、液化天然ガスは貯蔵タンク１７のポンプ１８によって圧力をかけられ、熱交換器１３を介して２つの制御弁７と１０へと送られる。蒸発器１２を通る天然ガスの流量は、弁１０により圧力センサー２１の測定値に基づいて制御され、蒸発器１２の中で生じたガスは噴霧タンク８の株領域に送られる。噴霧タンク８内で温度センサー９によって測定された温度で、第２のガス管システム２２の弁７における流量が調節され、液体状態かつ冷却されたガス（LNG）が噴霧タンク８の上部領域に送られる。噴霧タンク８内の噴霧装置３０によって液化天然ガスが噴霧されることで、噴霧タンク８の上部領域の蒸発ガスの温度がコントロールされて下げられる。さらに、メタン価に関して最適に調節されたガスが、液滴分離器５を介して内燃機関３および熱交換器６へと供給される。噴霧タンク８と液滴分離器５において集められた縮合物は、管１５と縮合物分離器１４を通り、再冷却熱交換器１３を経て、管１６を通って再び貯蔵タンク１７へと送られる。   Therefore, if more natural gas is needed in the engine than is emitted from the storage tank 17 as steam, this is recognized by the first gas pipe system 4 or the pressure sensor 21 of the storage tank 17 and added. Natural gas is supplied to the evaporator 12 by the control of the valve 10 in the second gas pipe system 22. In the gas pipe system 22, the liquefied natural gas is pressurized by the pump 18 of the storage tank 17 and sent to the two control valves 7 and 10 via the heat exchanger 13. The flow rate of the natural gas passing through the evaporator 12 is controlled by the valve 10 based on the measured value of the pressure sensor 21, and the gas generated in the evaporator 12 is sent to the stock area of the spray tank 8. The flow rate at the valve 7 of the second gas pipe system 22 is adjusted at the temperature measured by the temperature sensor 9 in the spray tank 8, and the liquid and cooled gas (LNG) is sent to the upper area of the spray tank 8. It is done. By spraying the liquefied natural gas by the spray device 30 in the spray tank 8, the temperature of the evaporated gas in the upper region of the spray tank 8 is controlled and lowered. Furthermore, a gas optimally adjusted with respect to the methane number is supplied to the internal combustion engine 3 and the heat exchanger 6 via the droplet separator 5. The condensate collected in the spray tank 8 and the droplet separator 5 passes through the pipe 15 and the condensate separator 14, passes through the recooling heat exchanger 13, and is sent again to the storage tank 17 through the pipe 16. .

第１の供給管４のコンプレッサー１を混合ポイント３１の前に配置することで、噴霧タンク８は内燃機関３の圧力水準で駆動される。   By arranging the compressor 1 of the first supply pipe 4 in front of the mixing point 31, the spray tank 8 is driven at the pressure level of the internal combustion engine 3.

以上の点を要約すると図１は、第１のガス管システム４と第２のガス管システム２２を有する、気体燃料で駆動される内燃機関３のためのガス供給装置を示している。冷却され液化された天然ガスを貯留する貯蔵タンク１７の中で該貯蔵タンク１７の温度上昇によって蒸発する天然ガスをNBOGとして、第１のガス管システム４を介して内燃機関３の方向に送り出すことができる。また、NBOGの量が駆動に充分でない場合、第２のガス管システム２２を通じて、冷却され液化された天然ガスを貯留する貯蔵タンク１７から液化天然ガスを取り出し、蒸発器１２に供給して一部をFBOGとして蒸発させた後にNBOGと混合させることができ、それによってNBOGとFBOGとの混合ガスを内燃機関３の方向に送り出すことができる。その際第２のガス管システム２２は、蒸発したガスを、蒸発器１２を介して噴霧タンク８へと送り、さらに制御弁７を介して、蒸発器１２から分かれた経路で液化ガスを噴霧タンク８へと送る。噴霧タンク８は温度センサー９と制御装置とを備えており、この制御装置は温度センサー９に従って、制御弁７を通る液化ガスの流量を調節する。その結果、蒸発器１２から出てくる蒸発したガスの温度は、噴霧タンク８内において液化ガスを噴霧することによってコントロールされて低下可能となり、ガス中の比重の大きい炭化水素は凝縮して液体の状態で噴霧タンク８から排出させることができ、そして所定のメタン価を有するガスが噴霧タンク８から内燃機関３へと供給されることができる。   To summarize the above points, FIG. 1 shows a gas supply device for an internal combustion engine 3 driven by gaseous fuel, having a first gas pipe system 4 and a second gas pipe system 22. In the storage tank 17 that stores the cooled and liquefied natural gas, the natural gas that evaporates due to the temperature rise of the storage tank 17 is sent to the internal combustion engine 3 via the first gas pipe system 4 as NBOG. Can do. If the amount of NBOG is not sufficient for driving, the liquefied natural gas is taken out from the storage tank 17 for storing the cooled and liquefied natural gas through the second gas pipe system 22 and supplied to the evaporator 12 to partially Can be mixed with NBOG after being evaporated as FBOG, whereby a mixed gas of NBOG and FBOG can be sent out in the direction of the internal combustion engine 3. At that time, the second gas pipe system 22 sends the evaporated gas to the spray tank 8 via the evaporator 12, and further the liquefied gas is sprayed to the spray tank via the control valve 7 through a route separated from the evaporator 12. Send to 8. The spray tank 8 includes a temperature sensor 9 and a control device, and the control device adjusts the flow rate of the liquefied gas through the control valve 7 according to the temperature sensor 9. As a result, the temperature of the evaporated gas coming out of the evaporator 12 can be controlled and lowered by spraying the liquefied gas in the spray tank 8, and hydrocarbons having a large specific gravity in the gas are condensed to form liquid. The gas can be discharged from the spray tank 8 in a state, and a gas having a predetermined methane number can be supplied from the spray tank 8 to the internal combustion engine 3.

噴霧タンク８内に形成された縮合物は、縮合物分離器１４によって貯蔵タンク１７に再び送られ得る。   The condensate formed in the spray tank 8 can be sent again to the storage tank 17 by the condensate separator 14.

第１のガス管システム４あるいは貯蔵タンク１７には、該貯蔵タンク１７内部の圧力を確認するために圧力センサー２１が設置されている。該圧力センサーおよび該センサーと協働する制御弁１０とによって、蒸発の出力すなわち蒸発器１２を通るFBOGの流量が、制御可能である。   A pressure sensor 21 is installed in the first gas pipe system 4 or the storage tank 17 in order to check the pressure inside the storage tank 17. By means of the pressure sensor and the control valve 10 cooperating with the sensor, the output of the evaporation, ie the flow rate of the FBOG through the evaporator 12, can be controlled.

噴霧タンク８から内燃機関３に向かって出て行ったガスは、液滴分離器５と熱交換器６とを通って前記内燃機関３に供給され得る。液滴分離器５内で形成された縮合物は、管１５によって貯蔵タンク１７に再び送られ得る。   The gas discharged from the spray tank 8 toward the internal combustion engine 3 can be supplied to the internal combustion engine 3 through the droplet separator 5 and the heat exchanger 6. The condensate formed in the droplet separator 5 can be sent again to the storage tank 17 by means of a tube 15.

液滴分離器５および／または縮合物分離器１４の縮合物の流れは、貯蔵タンク１７の前の熱交換器１３で再冷却され得る。   The condensate stream of the droplet separator 5 and / or the condensate separator 14 can be recooled in the heat exchanger 13 before the storage tank 17.

内燃機関３内で燃焼可能なNBOGとFBOGとの混合ガスを調達するための方法、すなわち冷却され液化された天然ガスを貯留する貯蔵タンク１７の中で該貯蔵タンク１７の温度上昇によって蒸発する天然ガスが、NBOGとして内燃機関３に向かって送り出され、また、NBOGの量が駆動に充分でない場合、貯蔵タンク１７から液化天然ガスが取り出され、蒸発器１２に供給されて一部がFBOGとして蒸発した後にNBOGと混合される、という方法は、蒸発したガスが少なくとも噴霧タンク８に供給される工程と、該噴霧タンク８内で通り抜けたガス（FBOG）の温度が貯蔵タンク１７からの液化天然ガス（LNG）を噴霧することにより下げられるため、ガス中の比重の大きい炭化水素が凝縮して液体の状態で取り出される、という工程とを備えている。   A method for procuring a mixed gas of NBOG and FBOG combustible in the internal combustion engine 3, that is, a natural gas that evaporates due to a rise in temperature of the storage tank 17 in a storage tank 17 that stores cooled and liquefied natural gas. When the gas is sent out as NBOG toward the internal combustion engine 3 and the amount of NBOG is not sufficient for driving, the liquefied natural gas is taken out from the storage tank 17 and supplied to the evaporator 12 to partially evaporate as FBOG. After that, the method of mixing with NBOG is a process in which evaporated gas is supplied to at least the spray tank 8, and the temperature of the gas (FBOG) passing through the spray tank 8 is liquefied natural gas from the storage tank 17. Since it is lowered by spraying (LNG), it comprises a step of condensing hydrocarbons having a large specific gravity in the gas and extracting them in a liquid state.

蒸発器１２を通って送られるガスはその際、噴霧タンク８の下部領域に送られ、噴霧されるべき相当量の液化ガスは、噴霧装置３０によって噴霧タンク８の上部領域に送られる。噴霧されるべき液化ガスの量は、噴霧タンク８内部の温度に応じて弁７に制御され、その結果噴霧タンク８上部領域のFBOGの温度はコントロールされて下げられる。   The gas sent through the evaporator 12 is then sent to the lower region of the spray tank 8 and a considerable amount of liquefied gas to be sprayed is sent by the spray device 30 to the upper region of the spray tank 8. The amount of liquefied gas to be sprayed is controlled by the valve 7 in accordance with the temperature inside the spray tank 8, and as a result, the temperature of the FBOG in the upper region of the spray tank 8 is controlled and lowered.

噴霧タンク８内のガスの温度は、温度センサー９により、噴霧装置３０の上部にある領域あるいは噴霧タンク８の後ろのガス誘導管において測定される。   The temperature of the gas in the spray tank 8 is measured by the temperature sensor 9 in the area above the spray device 30 or in the gas induction tube behind the spray tank 8.

噴霧タンク８は、内燃機関３のために高められた内圧で駆動される。   The spray tank 8 is driven at an increased internal pressure for the internal combustion engine 3.

図２から５は、内燃機関による駆動装置のための本発明に係るガス供給装置の更なる実施例であるが、不必要な反復を避けるために同じ構成要素には同じ符号が使われており、図２から５の実施例が、場合によっては図１の実施例とお互いに異なるようなものについてのみ、以下に詳述する。   FIGS. 2 to 5 are further embodiments of the gas supply device according to the invention for a drive by an internal combustion engine, but the same reference numerals are used for the same components to avoid unnecessary repetition. Only those embodiments of FIGS. 2-5, which may be different from the embodiment of FIG. 1 in some cases, will be described in detail below.

図２の実施例が図１の実施例と異なっているのは単に、混合ポイント３１と内燃機関３との間の、混合ガスの下流に圧力上昇装置１’が設置されている点である。その結果噴霧タンク８は貯蔵タンク１７の圧力水準の内圧で駆動される。   The embodiment of FIG. 2 differs from the embodiment of FIG. 1 only in that a pressure raising device 1 ′ is installed downstream of the mixed gas between the mixing point 31 and the internal combustion engine 3. As a result, the spray tank 8 is driven with the internal pressure of the pressure level of the storage tank 17.

これに対し図３はガス供給ユニットの実施例を示している。ここでは第１のガス管システム４’が噴霧タンク８を通過するのではなく、同様に噴霧タンク８を貫通している。また混合ポイント３１が蒸発器１２から噴霧タンク８への供給管２２内にある。圧力上昇装置１’は、内燃機関３に供給されるガスの下流において噴霧タンク８に後置され、その結果噴霧タンク８は貯蔵タンク１７の圧力水準の内圧で駆動される。   On the other hand, FIG. 3 shows an embodiment of the gas supply unit. Here, the first gas pipe system 4 ′ does not pass through the spray tank 8 but similarly passes through the spray tank 8.

In the embodiment of FIG. 4, the compressor 1 ″ instead of the compressor 1 ′ of the embodiment of FIG. Preceding the supply pipe 4, the spray tank 8 is consequently driven at the pressure level before the internal combustion engine 3.

このような実施形態により（図２にも記載されているように）、噴霧タンクの容積は思い切った小型化がなされている。NBOGのメタン価を上げるための、図３や４に従った実施例はとりわけ、NBOGの割合が高くFBOGの割合が低い状態で駆動している場合に、関心が高くなる。   With such an embodiment (as also described in FIG. 2), the volume of the spray tank is drastically reduced. The embodiment according to FIGS. 3 and 4 for increasing the methane number of NBOG is particularly interesting when driving with a high NBOG ratio and a low FBOG ratio.

図５は本発明に係るガス供給装置の更なる実施例を示している。この図では、噴霧タンク８の制御弁７と１０に液化ガスで圧力をかけるために、貯蔵タンク１７の外に設置された圧力上昇装置１９が配置されている。圧力上昇装置１９は前留出物用容器２０と協働し、液化ガスを吸い上げ、貯蔵タンク１７内にある圧力上昇装置１８によって前留出物用容器２０が満たされ得る。   FIG. 5 shows a further embodiment of the gas supply device according to the invention. In this figure, in order to apply pressure to the control valves 7 and 10 of the spray tank 8 with liquefied gas, a pressure raising device 19 installed outside the storage tank 17 is arranged. The pressure elevating device 19 cooperates with the pre-distillate container 20 to suck up the liquefied gas and the pre-distillate container 20 can be filled by the pressure elevating device 18 in the storage tank 17.

図５で表された実施形態は、図１から４までの実施形態のコンビネーションである。   The embodiment represented in FIG. 5 is a combination of the embodiments of FIGS.
