Description

本発明は、ガス機関または二種燃料機関として設計された内燃機関の始動準備のための、そして好ましくはその後の始動のための方法に関する。 The present invention relates to a method for starting, and preferably for subsequent starting, an internal combustion engine designed as a gas engine or a Type 2 fuel engine.

ここで述べる当業者は、ガス機関または二種燃料機関として設計された内燃機関の基本的な構成およびその基本的な動作モードに精通している。したがって、ガス機関は、典型的には、その中で例えばメタンのような専らガス状燃料が燃焼させられる複数のシリンダーを備える。典型的には、二種燃料機関は、同様に、第１の運転モードではディーゼルのような液体燃料を、そして第２の運転モードではメタンのようなガス状燃料をその中で燃焼させることができる複数のシリンダーを備える。ガス機関のシリンダーまたは二種燃料機関のシリンダーは、典型的には、直線状に配置された複数のシリンダーの少なくとも一つのグループ内に配置される。直線状に配置されたシリンダーの各グループは、個々のシリンダーグループ燃料供給ラインを介して、ガス状燃料を供給することができ、シリンダーの個々の供給ラインは、グループの各シリンダーを個々のシリンダーグループ燃料供給ラインに接続する、個々のシリンダーグループ燃料供給ラインから分岐している。 Those skilled in the art described herein are familiar with the basic configuration of an internal combustion engine designed as a gas engine or a Type 2 fuel engine and its basic mode of operation. Therefore, a gas engine typically comprises a plurality of cylinders in which exclusively gaseous fuel such as methane is burned. Typically, the Type 2 fuel engine may similarly burn a liquid fuel such as diesel in the first mode of operation and a gaseous fuel such as methane in the second mode of operation. Equipped with multiple cylinders that can. A gas engine cylinder or a Type 2 fuel engine cylinder is typically located within at least one group of linearly arranged cylinders. Each group of linearly arranged cylinders can be supplied with gaseous fuel via the individual cylinder group fuel supply lines, and the individual supply lines of cylinders each cylinder of the group to an individual cylinder group. Individual cylinder group branching from the fuel supply line, connecting to the fuel supply line.

ガス機関の場合、通常の運転中、すなわち特にガス機関が停止しているときでさえ、個々のシリンダーグループ燃料供給ラインは常にガス状燃料で満たされる。しかしながら、メンテナンス作業を行うために、個々のシリンダーグループ燃料供給ラインは通気され、ガス機関の次の始動のために、それぞれの個々のシリンダーグループ燃料供給ラインはガス状燃料で満たされなければならない。 In the case of gas engines, individual cylinder group fuel supply lines are always filled with gaseous fuel during normal operation, especially when the gas engine is shut down. However, for maintenance work, the individual cylinder group fuel supply lines must be ventilated and each individual cylinder group fuel supply line must be filled with gaseous fuel for the next start of the gas engine.

二種燃料機関の場合、個々のシリンダーグループ燃料供給ラインは、特にシリンダー内でガス状燃料が実際に燃焼させられるときにのみガス状燃料で満たされる。対照的に、例えばディーゼルのような液体燃料が二種燃料機関のシリンダー内で燃焼させられるとき、ガス状燃料用のそれぞれの個々のシリンダーグループ燃料供給ラインは通気され、特に空気または不活性ガスで満たされる。液体燃料が二種燃料機関において燃焼させられる二種燃料機関の運転モードから、ガス状燃料が二種燃料機関において燃焼させられる運転モードへと変更するために、それぞれの個々のシリンダーグループ燃料供給ラインは、規定された様式でガス状燃料によって満たされなければならない。二種燃料機関がガス状燃料で始動される場合にも同じ状況が存在する。 In the case of a Type 2 fuel engine, the individual cylinder group fuel supply lines are filled with gaseous fuel, especially when the gaseous fuel is actually burned in the cylinder. In contrast, when liquid fuels such as diesel are burned in the cylinders of a Type 2 fuel engine, each individual cylinder group fuel supply line for gaseous fuels is ventilated, especially with air or inert gas. It is filled. Each individual cylinder group fuel supply line to change from a type 2 fuel engine operating mode in which liquid fuel is burned in a type 2 fuel engine to a mode in which gaseous fuel is burned in a type 2 fuel engine. Must be filled with gaseous fuel in the prescribed manner. The same situation exists when the Type 2 fuel engine is started with gaseous fuel.

今日まで、液体燃料運転モードからガス状燃料運転モードへと変更するとき、ガス状燃料が燃料供給ラインからなくなった状態でメンテナンス作業を実施した後にガス機関を、そして二種燃料機を適切に始動することは困難である。したがって、ガス機関または二種燃料機関として設計された内燃機関の始動準備のための方法が必要であり、その助けによって、特に、ガス状燃料ライン用のそれぞれの個々のシリンダーグループ燃料供給ラインにガス状燃料がなくなったとき、ガス機関または二種燃料機関をガス状燃料で安全かつ確実に始動させることができる。 To date, when changing from liquid fuel operating mode to gaseous fuel operating mode, properly start the gas engine and the Type 2 fuel machine after performing maintenance work with the gaseous fuel running out of the fuel supply line. It's difficult to do. Therefore, there is a need for a method for starting preparation of an internal combustion engine designed as a gas engine or a Type 2 fuel engine, and with its help, gas in each individual cylinder group fuel supply line, especially for gaseous fuel lines. When the fuel is exhausted, the gas engine or the type 2 fuel engine can be started safely and reliably with the gaseous fuel.

このことから出発して、本発明は、ガス機関または二種燃料機関として設計された内燃機関の始動準備のための新規なタイプの方法を創出するという目的に基づいている。 Starting from this, the present invention is based on the object of creating a novel type of method for starting preparation of an internal combustion engine designed as a gas engine or a type 2 fuel engine.

この目的は、請求項１に記載の方法によって解決される。 This object is solved by the method according to claim 1.

第１のステップａ）においては、ガス状燃料が排出されると共に特に周囲空気または不活性ガスで満たされたそれぞれの個々のシリンダーグループ燃料供給ラインが、規定の様式で最初にガス状燃料によって満たされ、そして個々のシリンダーグループ燃料供給弁の閉鎖後に、それぞれの個々のシリンダーグループ燃料供給ラインに存在する圧力が規定の時間間隔にわたって規定の圧力範囲内に存在するかどうかがプロセス中にモニターされる。特に、ステップａ）において、それぞれの個々のシリンダーグループ燃料供給ライン内に存在する圧力が、規定された時間間隔にわたって規定された圧力範囲内に存在することが確証されたとき、ガスの流れ方向におけるグループの最後のシリンダーに、あるいはグループの最後のシリンダーのそれぞれの個々のシリンダー燃料供給ラインに対して割り当てられた個々のシリンダーグループ燃料供給弁を開き、続いて閉じることによって、次のステップｂ）において、それぞれの個々のシリンダーグループ燃料供給ラインにガス状燃料が均等に分配される。その後のステップｃ）では、内燃機関をガス状燃料で始動させることができる。本発明による方法では、それぞれの個々のシリンダーグループ燃料供給ラインは、最初に、ステップａ）において漏れ試験を受ける。特にステップａ）において個々のシリンダーグループ燃料供給ラインに漏れ耐性があることが確証された場合にのみ、次のステップｂ）においてガス状燃料が個々のシリンダーグループ燃料供給ラインに均等に分配され、これに続いて、始動準備の完了時、内燃機関は次のステップｃ）においてガス状燃料で始動させられる。 In the first step a), each individual cylinder group fuel supply line filled with ambient air or inert gas as the gaseous fuel is discharged is first filled with the gaseous fuel in a prescribed manner. And after closing the individual cylinder group fuel supply valves, it is monitored during the process whether the pressure present in each individual cylinder group fuel supply line is within the specified pressure range over the specified time interval. .. In particular, in step a), when it is confirmed that the pressure present in each individual cylinder group fuel supply line is within the specified pressure range over the specified time interval, in the gas flow direction. In the next step b) by opening and then closing the individual cylinder group fuel supply valves assigned to the last cylinder of the group or to each individual cylinder fuel supply line of the last cylinder of the group. , The gaseous fuel is evenly distributed to each individual cylinder group fuel supply line. In the subsequent step c), the internal combustion engine can be started with gaseous fuel. In the method according to the invention, each individual cylinder group fuel supply line is first subjected to a leak test in step a). In particular, only if it is confirmed in step a) that the individual cylinder group fuel supply lines are leak resistant, in the next step b) the gaseous fuel is evenly distributed to the individual cylinder group fuel supply lines. Subsequently, when the start preparation is completed, the internal combustion engine is started with gaseous fuel in the next step c).

特に、ステップａ）において、個々のシリンダーグループ燃料供給ライン内に存在する圧力が規定された時間間隔にわたって規定された圧力範囲内に存在しないことが確証されたとき、始動準備が優先的に中止される。ステップａ）において、それぞれの個々のシリンダーグループ燃料供給ラインの漏れが確証されると、始動準備が中止され、内燃機関は続いてガス状燃料によって始動させられない。 In particular, in step a), when it is confirmed that the pressure present in the individual cylinder group fuel supply lines is not within the specified pressure range over the specified time interval, the start preparation is preferentially aborted. To. In step a), if a leak in each individual cylinder group fuel supply line is confirmed, the start preparation is stopped and the internal combustion engine is subsequently not started by the gaseous fuel.

Regarding the method.

本発明による方法は、図１ないし図４を参照して以下で説明されるが、図１ないし図４は、本発明による方法が実施される間に内燃機関１０が呈し得る、その異なる状態を示している。 The method according to the invention will be described below with reference to FIGS. 1 to 4, but FIGS. 1 to 4 show the different states that the internal combustion engine 10 may exhibit while the method according to the invention is being carried out. Shows.

図１ないし図４に非常に概略的に示されている内燃機関１０は、直線状に配置されたシリンダー１２のグループ１１を有する。シリンダー１２のグループ１１には、個々のシリンダーグループ燃料供給ライン１３を介してガス状燃料を供給することができ、個々のシリンダー燃料供給ライン１４は個々のシリンダーグループ燃料供給ライン１３から分岐するが、これを介して、個々のシリンダーグループ燃料供給ライン１３からのガス状燃料を個々のシリンダー１２に供給することができる。 The internal combustion engine 10, which is shown very schematically in FIGS. 1 to 4, has a group 11 of cylinders 12 arranged in a straight line. The group 11 of the cylinders 12 can be supplied with gaseous fuel via the individual cylinder group fuel supply lines 13, although the individual cylinder fuel supply lines 14 branch off from the individual cylinder group fuel supply lines 13. Through this, gaseous fuel from the individual cylinder group fuel supply lines 13 can be supplied to the individual cylinders 12.

図１によれば、個々のシリンダーグループ燃料供給ライン１３には、個々のシリンダーグループ燃料供給弁１５が割り当てられる。特に、個々のシリンダーグループ燃料供給弁１５が開かれているとき、個々のシリンダーグループ燃料供給ライン１３は、ガス状燃料で満たすことができる。各個々のシリンダー燃料供給ライン１４には個々のシリンダー燃料供給弁１６が割り当てられ、代替的に、この個々のシリンダー燃料供給弁１６はシリンダー１２に割り当てられる。個々のシリンダー燃料供給弁１６が開いているか閉じているかに応じて、特に個々のシリンダーグループ燃料供給ライン１３がガス状燃料で満たされているとき、それぞれのシリンダー１２には、個々のシリンダーグループ燃料供給ライン１３からのガス状燃料を供給することができる。 According to FIG. 1, each cylinder group fuel supply line 13 is assigned an individual cylinder group fuel supply valve 15. In particular, when the individual cylinder group fuel supply valves 15 are open, the individual cylinder group fuel supply lines 13 can be filled with gaseous fuel. Each individual cylinder fuel supply line 14 is assigned an individual cylinder fuel supply valve 16, and instead, this individual cylinder fuel supply valve 16 is assigned to a cylinder 12. Each cylinder 12 has an individual cylinder group fuel, depending on whether the individual cylinder fuel supply valves 16 are open or closed, especially when the individual cylinder group fuel supply lines 13 are filled with gaseous fuel. The gaseous fuel from the supply line 13 can be supplied.

図１は、個々のシリンダーグループ燃料供給ライン１３にはガス状燃料が存在しないが、図１の個々のシリンダーグループ燃料供給ライン１３から、通気弁１７を介して、例えばガス状燃料が排出され、そしてそれが空気、例えばＯ２および／または不活性ガスを含む周囲空気で満たされた内燃機関１０の状態を示している。 In FIG. 1, there is no gaseous fuel in the individual cylinder group fuel supply lines 13, but for example, gaseous fuel is discharged from the individual cylinder group fuel supply lines 13 in FIG. 1 through the vent valve 17. And it shows the state of the internal combustion engine 10 filled with air, eg O 2 and / or ambient air containing an inert gas.

本発明は、始動準備のための、そして適切ならば内燃機関をガス状燃料で安全かつ確実に始動させることができる、そうした内燃機関のその後の始動のための方法のそうした詳細に関する。 The present invention relates to such details of a method for subsequent starting of such an internal combustion engine in preparation for starting and, where appropriate, the internal combustion engine can be safely and reliably started with gaseous fuel.

本発明による始動準備のための方法の第１のステップａ）においては、ガス状燃料が排出されると共に空気および／または不活性ガスで満たされた個々のシリンダーグループ燃料供給ライン１３は、最初に、個々のシリンダーグループ燃料供給弁１５を開くことによって、規定の様式で、ガス状燃料で満たされるが、当該プロセスでは、個々のシリンダーグループ燃料供給弁１５は規定の時間間隔だけ開き、その後、再び閉じられる。個々のシリンダー燃料供給弁１６は閉じられ、この間中、閉じられたままである。図２は、個々のシリンダーグループ燃料供給ライン１３の、ガス状燃料としてのメタンによる充填を示している。 In the first step a) of the method for starting preparation according to the present invention, the individual cylinder group fuel supply lines 13 filled with air and / or inert gas as the gaseous fuel is discharged are first. , The individual cylinder group fuel supply valves 15 are filled with gaseous fuel in the prescribed manner by opening the individual cylinder group fuel supply valves 15, but in the process the individual cylinder group fuel supply valves 15 are opened for the specified time intervals and then again. Closed. The individual cylinder fuel supply valves 16 are closed and remain closed during this time. FIG. 2 shows the filling of individual cylinder group fuel supply lines 13 with methane as a gaseous fuel.

個々のシリンダーグループ燃料供給弁１５の閉鎖に続いて、圧力センサー１８の助けによって、図３に示すように、個々のシリンダーグループ燃料供給弁１５の閉鎖に続いて、個々のシリンダーグループ燃料供給ライン１３内に存在する圧力が、規定の時間間隔にわたって、規定の圧力範囲内に存在するかどうかが確認される。個々のシリンダーグループ燃料供給弁１５および個々のシリンダーグループ燃料供給弁１６は閉じられ、この間中、閉じられたままである。 Following the closure of the individual cylinder group fuel supply valves 15, with the help of the pressure sensor 18, following the closure of the individual cylinder group fuel supply valves 15, the individual cylinder group fuel supply lines 13 as shown in FIG. It is checked whether the pressure existing in is within the specified pressure range over the specified time interval. The individual cylinder group fuel supply valves 15 and the individual cylinder group fuel supply valves 16 are closed and remain closed during this time.

特に、ステップａ）において、個々のシリンダーグループ燃料供給ライン１３内に存在する圧力が規定された時間間隔にわたって規定された圧力範囲内にあることが確証されたとき、ガス状燃料は、個々のシリンダーグループ燃料供給弁１５から見てシリンダーグループ１１の最後のシリンダーに、あるいはグループ１１の最後のシリンダー１２のそれぞれの個々のシリンダー燃料供給ライン１４に割り当てられた個々のシリンダー燃料供給弁１６（図４参照）の開放およびそれに続く閉鎖によって、続く第２のステップｂ）において、それぞれの個々のシリンダーグループ燃料供給ライン１３に均等に分配され、そしてこのプロセスにおいて、個々のシリンダーグループ燃料供給ライン１３は、ステップａ）において前もってその中に導入されたガス状燃料で完全に満たされるが、このプロセスにおいて、個々のシリンダーグループ燃料供給ライン１３からある残量の空気が除去される。個々のシリンダーグループ燃料供給弁１５および別な個々のシリンダー燃料供給弁１６（これは最初の二つの最後から２番目のシリンダー１２に割り当てられたる）は閉じられ、この間中、閉じられたままである。 In particular, in step a), when it is confirmed that the pressure present in the individual cylinder group fuel supply lines 13 is within the specified pressure range over the specified time interval, the gaseous fuel is in the individual cylinders. Individual cylinder fuel supply valves 16 assigned to the last cylinder of cylinder group 11 as viewed from group fuel supply valve 15 or to each individual cylinder fuel supply line 14 of the last cylinder 12 of group 11 (see FIG. 4). ) And subsequent closures are evenly distributed to each individual cylinder group fuel supply line 13 in the subsequent second step b), and in this process the individual cylinder group fuel supply lines 13 are stepped. In a) it is completely filled with the gaseous fuel previously introduced therein, but in this process a certain amount of air is removed from the individual cylinder group fuel supply lines 13. The individual cylinder group fuel supply valve 15 and another individual cylinder fuel supply valve 16 (which are assigned to the first two last to second cylinders 12) are closed and remain closed during this time.

したがって、実際の始動準備が完了し、その後のステップｃ）において、内燃機関１０をガス状燃料で安全かつ確実に始動させることができる。 Therefore, the actual preparation for starting is completed, and in the subsequent step c), the internal combustion engine 10 can be safely and reliably started with the gaseous fuel.

特に、第１のステップａ）において、個々のシリンダーグループ燃料供給弁１５の開閉によって個々のシリンダーグループ燃料供給ライン１３の規定された充填に続いて、個々のシリンダーグループ燃料供給ライン１３内に存在する圧力が規定された時間間隔にわたって規定された圧力範囲内に存在しないことが確証された場合、ガス状燃料のための燃料供給システムの漏れが断定され、始動準備が中止され、そして内燃機関は続いてガス状燃料を用いて始動させられない。 In particular, in the first step a), it is present in the individual cylinder group fuel supply lines 13 following the defined filling of the individual cylinder group fuel supply lines 13 by opening and closing the individual cylinder group fuel supply valves 15. If it is confirmed that the pressure is not within the specified pressure range over the specified time interval, a leak in the fuel supply system for gaseous fuel is determined, the start preparation is discontinued, and the internal combustion engine continues. Cannot be started with gaseous fuel.

個々のシリンダーグループ燃料供給ライン１３にガス状燃料が均等に分配される第２のステップｂ）では、各バンク１１における最後のシリンダー１２のそれぞれの個々のシリンダー燃料供給弁１６を開放することによって、個々のシリンダーグループ燃料供給ライン１３内の圧力は大気圧まで優先的に低下させられる。 In the second step b), where the gaseous fuel is evenly distributed to the individual cylinder group fuel supply lines 13, by opening each individual cylinder fuel supply valve 16 of the last cylinder 12 in each bank 11. The pressure in the individual cylinder group fuel supply lines 13 is preferentially reduced to atmospheric pressure.

この第２のステップｂ）において、個々のシリンダーグループ燃料供給ライン１３内の圧力は、優先的には、バンク内の最後のシリンダー１２の個々のシリンダー燃料供給弁１６の連続した複数回の記録された開閉によって、所定の設定勾配を伴って低下させられる。 In this second step b), the pressure in the individual cylinder group fuel supply lines 13 is preferentially recorded multiple times in a row for the individual cylinder fuel supply valves 16 of the last cylinder 12 in the bank. By opening and closing, it is lowered with a predetermined setting gradient.

このプロセスにおいて生じる実際の勾配が確定されると共に設定勾配と比較され、特に、実際の勾配が設定勾配から閾値を超えて逸脱した場合、バンク１１のそれぞれの最後のシリンダー１２の目詰まりした個々のシリンダー燃料供給弁１６が断定され、始動準備が同様に中止される。特に、ステップｂ）を具現化する実際の勾配が閾値を超えて各設定勾配から逸脱しない場合にのみ、次の第３のステップｃ）において内燃機関がガス状燃料で実際に始動させられる。 The actual gradient generated in this process is determined and compared to the set gradient, especially if the actual gradient deviates beyond the threshold from the set gradient, the clogged individual of each last cylinder 12 of the bank 11. The cylinder fuel supply valve 16 is determined and the start preparation is similarly stopped. In particular, the internal combustion engine is actually started with gaseous fuel in the next third step c) only if the actual gradient embodying step b) exceeds the threshold and does not deviate from each set gradient.

したがって、シリンダー１２のグループ１１に通じる個々のシリンダーグループ燃料供給ライン１３が漏れ耐性があるか否かを確認するために、ステップａ）において、本発明によって、規定された漏れ試験が実施される。この目的のために、それぞれの個々のシリンダーグループ燃料供給ライン１３は規定された様式にてガス状燃料で満たされ、そしてその中の圧力が一定のままであるかグリッドから著しく低下するかがチェックされる。臨界的圧力低下の場合には、ガス状燃料用の供給システムにおける漏れが断定され、始動準備が中止され、そして燃料としてガスを用いた機関の始動が阻止される。 Therefore, in step a), the leak test specified by the present invention is carried out in order to confirm whether or not the individual cylinder group fuel supply lines 13 leading to the group 11 of the cylinder 12 are leak resistant. For this purpose, each individual cylinder group fuel supply line 13 is filled with gaseous fuel in a defined manner and checked if the pressure in it remains constant or drops significantly from the grid. Will be done. In the case of a critical pressure drop, a leak in the supply system for gaseous fuel is determined, start-up preparation is aborted, and start-up of the engine using gas as fuel is prevented.

しかしながら、対照的に、漏れ試験が成功した場合、すなわち、ガス状燃料用の燃料供給システムにおける漏れの問題が検出されない場合、開始準備が継続され、ステップｂ）において、ガス状燃料が、グループ１１の最後のシリンダー１２の燃料供給弁１６を開くことによって、個々のシリンダーグループ燃料供給ライン１３に均等に供給される。その後、内燃機関１０は、ステップｃ）において、規定された様式で始動させることができる。 However, in contrast, if the leak test is successful, i.e., if no leak problem is detected in the fuel supply system for the gaseous fuel, the start preparation is continued and in step b) the gaseous fuel is group 11. By opening the fuel supply valve 16 of the last cylinder 12, the fuel is evenly supplied to the individual cylinder group fuel supply lines 13. After that, the internal combustion engine 10 can be started in the specified manner in step c).

ステップｂ）の間に、最後のシリンダー１２に割り当てられた個々のシリンダー燃料供給弁１６が漏れていることが分かった場合、始動準備が同様に中止され、内燃機関１０のその後の始動が阻止される。予め、限られた量のガス状燃料しか個々のシリンダーグループ燃料供給ライン１３に導入されていないので、ガス状燃料が、例えば充填空気システムのような隣接部品システム内にあふれるリスクはない。 If during step b) it is found that the individual cylinder fuel supply valves 16 assigned to the last cylinder 12 are leaking, start preparation is similarly aborted and subsequent start of the internal combustion engine 10 is blocked. Cylinder. Since only a limited amount of gaseous fuel has been previously introduced into the individual cylinder group fuel supply lines 13, there is no risk of the gaseous fuel overflowing into an adjacent component system such as a filled air system.

シリンダー１２の複数のグループ１１を有する内燃機関１０の場合、その始動は、シリンダー１２のグループ１１のそれぞれに関して、上述したように支障を伴わずに上記ステップａ）およびｂ）が行われ、したがって漏れが検出されなかったときにのみ実施される。 In the case of an internal combustion engine 10 having a plurality of groups 11 of cylinders 12, the start of each of the groups 11 of cylinders 12 is undisturbed as described above in steps a) and b) and thus leaks. Is only performed when is not detected.
