Description
Technical Field
The invention relates to a Gas storage device, in particular a Gas rail (Gas rail). The gas storage device can thus be in particular a gas storage line to which a plurality of injectors are attached, individually or in groups, for metering in (Eindosieren) gas.
A preferred field of application of the gas storage device is a gas supply system for supplying gas to a gas engine, whereby the invention also relates to a gas supply system with a gas storage device according to the invention and a gas engine with a gas supply system according to the invention.
The gas stored in the gas storage device may be in particular hydrogen or methane.
Background
A plurality of injectors for injecting or blowing fuel into the combustion chamber of an internal combustion engine are known from the prior art. The seal seats of these injectors are usually arranged close to the combustion chamber, so that the thermal load is high.
Since injectors for blowing in gases, such as hydrogen or methane, have to meet higher tightness requirements, the sealing seat is usually made of an elastic material, in particular a plastic, such as a polymer. The elasticity of the material results in a higher tightness. However, the temperature sensitivity is also increased, so that the service life of the injector is limited in the case of a sealing seat arranged close to the combustion chamber.
Thus, the following gas injectors have been proposed: in the gas injector, the seal seat is arranged farther from the combustion chamber. In addition, injectors are proposed which have a passive switching element which enables sealing of the combustion chamber in the event of an increase in the combustion chamber pressure. Further, the following gas injectors are known: the gas injector has an integrated second actuator for achieving a shut-off function. However, this solution has the following drawbacks: the installation space requirement of such an injector is relatively large.
Disclosure of Invention
Starting from the prior art mentioned above, the invention is based on the object of enabling a selective shut-off of an injector or an injector group without an integrated second actuator. In this way, the installation space requirement should be reduced. In the event of a fault, i.e. in the event of a defect in the individual injectors, emergency operation can also be achieved by selective switching off.
To solve this task, a gas storage device having the features of claim 1, a gas supply system having the features of claim 8 and a gas engine having the features of claim 9 are proposed.
A gas storage device, in particular a gas rail, is proposed, which comprises at least one attachment area for attaching an injector or an injector group. In this case, a controllable valve is integrated into the attachment region, which valve serves to shut off the injector or the injector group. The injector or the injector group can be switched off in a targeted manner by means of a controllable valve. Here, the valve is not integrated into the injector or the injector group, but into the gas storage device. The installation space requirements of the injector or of the injector group therefore remain unchanged.
In particular, when a plurality of injectors are attached to the gas storage device either individually or in groups, the shut-off function realized via the valve that can be actuated takes effect. This is because, in the event of a fault, the injectors or groups of injectors can be switched off in a targeted manner in order to be able to carry out emergency operation.
In one embodiment of the invention, it is therefore provided that the gas storage device has a plurality of attachment areas arranged in parallel, in each of which an actuatable valve is integrated, which valve is connected or connectable to the injector or the injector group via at least one injector inlet line. By means of the proposed parallel arrangement of the attachment areas and of the valves integrated into them, which valves can be actuated, a distributor function is achieved which enables a uniform gas distribution to all valves. The available installation space is at the same time optimally utilized, since the gas storage device has an elongated basic shape, in particular in the form of a gas rail. Preferably, the gas storage device has a main storage line with a plurality of branches, which constitute a plurality of attachment areas arranged in parallel.
Preferably, at least one controllable valve for closing the injector or the injector group can be actuated electromagnetically and comprises a ring-shaped solenoid for acting on a movable solenoid armature which is acted on by the spring force of a spring in the direction of the sealing seat. In the absence of current to the solenoid, the spring presses the solenoid armature in the direction of the sealing seat, thus ensuring a reliable closing of the valve.
Preferably, the magnet armature is surrounded at least in sections by a magnet coil. I.e. the magnet armature is designed as a plug-in armature or operates according to the plug-in armature principle. In this way, a very compact arrangement can be achieved, which can be integrated into a gas storage device in a simple manner.
Furthermore, the solenoid armature is preferably coupled to the valve closing element or forms the valve closing element. If a separate valve closing element is provided, it can be made of a different material than the electromagnetic armature, so that a better material coordination (materiallabstimmung) can be achieved. Integrating the function of the valve closing element into the solenoid armature enables a more compact design of the valve.
It is furthermore proposed that the gas storage device has an attachment end via which gas in the tank system can be supplied to the gas storage device. Gas may be stored in the tank system and carried on a gas-operated vehicle. Preferably, the attachment with the tank system is implemented tubular. This facilitates the attachment of a gas line, preferably via which the tank system is connected with the gas storage device. Alternatively or additionally, it is proposed that the attachment end is arranged on the end side of the gas storage device. In this way, the space available is optimally utilized.
In addition, a gas supply system for supplying a gas, such as hydrogen or methane, to a gas engine is proposed. The gas supply system comprises a gas storage device according to the invention and at least one injector or group of injectors, which are attached to the gas storage device via a valve integrated into the attachment area that can be actuated. Preferably, a plurality of injectors or injector groups are provided, each of which belongs to a cylinder of the gas engine. In other words, a plurality of valves that can be actuated are integrated into the gas storage device, so that the injectors or injector groups can be selectively switched off, preferably in a single cylinder.
The gas supply system differs from the gas storage device in that the injector or the set of injectors is an integral part of the system. The further component of the gas supply system may be a tank system, which is connected to the gas storage device via a further attachment end.
Furthermore, a gas engine having a gas supply system according to the present invention is proposed, the gas engine having a plurality of cylinders. In this case, each cylinder is assigned a valve which can be actuated in conjunction with the associated injector or the associated injector group, so that the injector or the injector group can be shut off in individual cylinders (zyldiveridiell).

Detailed Description
In fig. 1 a gas supply system 12 for a gas engine according to the invention is shown. The illustrated gas supply system 12 comprises a gas storage device 1 according to the invention, which is embodied as a gas rail. Attached to the gas storage device 1 are a plurality of injectors 3, by means of which the gas in the gas storage device 1 can be blown into a gas engine (not shown), in particular into a cylinder of the gas engine. Here, each injector 3 is associated with a cylinder.
The attachment of the injectors 3 is effected via attachment areas 2 of the gas storage device 1, in which attachment areas valves 5 are respectively arranged, which valves are connected to the injectors 3 via injector input lines 6. The valve 5 can be actuated, preferably electromagnetically actuated, so that the associated injector 3 can be switched off in a targeted manner when the valve 5 is actuated accordingly. Thus, in the event of a fault or in the event of a defect in the injector 3, an emergency operation can be effected.
The attachment areas 2 of the gas storage device 1 are arranged parallel to each other so that the gas present in the gas storage device 1 is evenly distributed over the plurality of injectors 3 if the valve 5 located upstream is opened. Gas enters the gas storage device 1 via an attachment end 11 via which the gas storage device 1 can be connected with a tank system (not shown). The attachment end 11 is embodied in a tubular manner and is arranged on the end side.
Another preferred embodiment of a gas supply system 12 according to the present invention can be seen from fig. 2. The gas supply system differs from the gas supply system of fig. 1 in that each valve 5 is connected to the ejector group 4, so that the entire ejector group 4 can be shut off via the valve 5. For this purpose, each valve 5 is connected to a plurality of injectors 3 via an injector feed line 6.
Fig. 3 shows another preferred embodiment of a gas supply system 12 according to the present invention. Similarly to the embodiment according to fig. 1, each valve 5 is connected to one respective injector 3. The valves 5 can each be actuated electromagnetically. As shown by way of example in fig. 3, the valve can have a ring-shaped solenoid 7 and a reciprocating solenoid armature 8, which interacts with the solenoid 7. A particularly compact arrangement is achieved if the magnet armature 8 is embodied as a plug-in armature and at the same time forms a valve closing element which cooperates with the sealing seat 9, so that a separate valve closing element can be dispensed with. In order to reliably close the valve 5 when the magnet armature 7 is not energized, a spring 10 is provided, the spring force of which presses the magnet armature 8 in the direction of the sealing seat 9.
Fig. 4 shows another preferred embodiment of a gas supply system 12 according to the present invention. Similar to the embodiment of fig. 2, each valve 5 is connected to the injector group 4, so that the entire injector group 4 is shut off when the valves 5 are actuated accordingly. For this purpose, each valve 5 is connected to a plurality of injectors 3 via an injector feed line 6. In other respects, the embodiment of fig. 4 may be identically configured to the embodiment of fig. 3.
