Definitions
- Gas storage device gas supply system and gas engine
- the invention relates to a gas storage device, in particular a gas rail.
- the gas storage device can therefore in particular be a gas storage line to which a plurality of injectors—each individually or combined in groups—are connected for metering in gas.
- the preferred area of application of the gas storage device is a gas supply system for supplying a gas engine with gas, so that 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 that is stored in the gas storage device can be hydrogen or methane in particular.
- a variety of injectors for injecting or blowing fuel into a combustion chamber of an internal combustion engine is known from the prior art.
- the sealing seat of these injectors is usually arranged close to the combustion chamber, so that the thermal load is high.
- the sealing seat is usually made of an elastic material, in particular plastic, for example a polymer.
- the elasticity of the material leads to a higher tightness.
- the temperature sensitivity increases, so that the service life of the injector is limited if the sealing seat is arranged close to the combustion chamber.
- Gas injectors have therefore already been proposed in which the sealing seat is arranged further away from the combustion chamber.
- injectors with a passive switching element have been proposed that allow the combustion chamber to be sealed when the combustion chamber pressure increases.
- gas injectors with an integrated second actuator for realizing a shut-off function are known.
- this solution has the disadvantage that the space required for such an injector is comparatively large.
- the present invention is based on the object of enabling an injector or an injector group to be switched off selectively without an integrated second actuator. In this way, the space requirement is to be reduced. In the event of a fault, i.e. if there is a single defective injector, selective shutdown should continue to allow emergency operation.
- the gas storage device with the features of claim 1 the gas supply system with the features of claim 8 and the gas engine with the features of claim 9 are proposed.
- a gas storage device in particular a gas rail, which comprises at least one connection area for the connection of an injector or an injector group.
- a controllable valve for switching off the injector or the injector group is integrated in the connection area. With the help of the controllable valve, the injector or the injector group can be switched off in a targeted manner.
- the valve is not integrated in the injector or in the injector group, but in the gas storage device. The space requirement of the injector or the injector group remains unchanged.
- the switch-off function implemented via the controllable valve comes into play in particular when a plurality of injectors are connected to the gas storage device, either individually or combined in groups. Because then In the event of a fault, an injector or an injector group can be switched off in a targeted manner in order to enable emergency operation.
- the gas storage device has a plurality of connection areas arranged in parallel, in each of which a controllable valve is integrated, which is or can be connected to an injector or an injector group via at least one injector supply line.
- the proposed parallel arrangement of the connection areas and the controllable valves integrated into them create a distribution function that enables the gas to be evenly distributed to all valves.
- the available installation space is optimally used, since the gas storage device, particularly in the form of a gas rail, has an elongated basic shape.
- the gas storage device preferably has a main storage line with a number of branches, which form the number of connection areas arranged in parallel.
- the at least one controllable valve for switching off an injector or an injector group can preferably be actuated electromagnetically and comprises an annular magnet coil for acting on a movable magnet armature which is acted upon by the spring force of a spring in the direction of a sealing seat.
- the magnet coil When the magnet coil is de-energized, the spring presses the magnet armature in the direction of the sealing seat, so that the valve closes securely.
- the magnet armature is preferably at least partially surrounded by the magnet coil. This means that the magnet armature is designed as a plunger or works according to the plunger principle. In this way, a very compact arrangement can be created that can be easily integrated into the gas storage device.
- the magnet armature is preferably coupled to a valve closing element or forms a valve closing element. If a separate valve closing element is provided, it can be made from a different material than the magnet armature, so that better material matching is possible.
- the integration of the function of the valve closing element in the magnet armature enables an even more compact design of the valve.
- the gas storage device has a connection via which gas from a tank system can be supplied to the gas storage device.
- the gas can be stored in the tank system and carried on board a gas-powered vehicle.
- the connection to the tank system is preferably in the form of a socket. This facilitates the connection of a gas line, via which the tank system is preferably connected to the gas storage device.
- the connection is arranged on an end face of the gas storage device. In this way, the available tree is optimally used.
- a gas supply system for supplying a gas engine with gas, for example with hydrogen or methane, is proposed.
- the gas supply system comprises a gas storage device according to the invention and at least one injector or an injector group which is connected to the gas storage device via the controllable valve integrated into the connection area.
- a plurality of injectors or injector groups are preferably provided, each of which is assigned to a cylinder of the gas engine. This means that several controllable valves are integrated into the gas storage device in order to be able to switch off the injectors or injector groups selectively, preferably individually for each cylinder.
- the gas supply system differs from the gas storage device in that the injectors or injector groups are part of the system.
- a further component of the gas supply system can be a tank system which is connected to the gas storage device via a further connection.
- Each cylinder is assigned a controllable valve with the associated injector or the associated injector group, so that the injectors or injector groups can be switched off individually for each cylinder.
- FIG. 2 shows a schematic representation of a gas supply system with a gas storage device according to the invention according to a second preferred embodiment
- Fig. 3 is a schematic representation of a modification of the embodiment of Figure 1 and
- Fig. 4 shows a schematic representation of a modification of the embodiment of Figure 2.
- FIG. 1 shows a gas supply system 12 according to the invention for a gas engine.
- the gas supply system 12 shown comprises a gas storage device 1 according to the invention, which is designed as a gas rail.
- Several injectors 3 are connected to the gas storage device 1, by means of which gas from the gas storage device 1 can be injected into a gas engine (not shown), in particular a cylinder of a gas engine.
- Each injector 3 is assigned to a cylinder.
- the injectors 3 are connected via connection areas 2 of the gas storage device 1, in each of which a valve 5 is arranged, which is connected to an injector 3 via an injector supply line 6.
- the valve 5 can be controlled, preferably elec romagnetically actuated, so that when the valve 5 is controlled accordingly, the associated injector 3 can be switched off in a targeted manner. In the event of a fault or in the case of a defective injector 3, emergency operation can thus be implemented.
- connection areas 2 of the gas storage device 1 are parallel to each other is arranged so that in the gas storage device 1 existing gas evenly on the several injectors 3 is distributed, provided that the upstream valve 5 is open.
- the gas enters the gas storage device 1 via a connection 11, via which the gas storage device 1 can be connected to a tank system (not shown).
- the connection 11 is designed like a socket and is arranged on the front side.
- FIG. 2 shows a further preferred embodiment of a gas supply system 12 according to the invention. This differs from that in FIG. 1 in that each valve 5 is connected to an injector group 4 so that the entire injector group 4 can be switched off via the valve 5 .
- each valve 5 is connected to a plurality of injectors 3 via injector supply lines 6 .
- FIG. 3 shows a further preferred embodiment of a gas supply system 12 according to the invention.
- the valves 5 can each be actuated electromagnetically.
- a particularly compact arrangement is created when the magnet armature 8 is designed as a plunger and at the same time forms a valve closing element that interacts with a sealing seat 9, so that a separate valve closing element can be dispensed with.
- a spring 10 is provided whose Fe derkraft pushes the magnet armature 8 in the direction of the sealing seat 9 .
- FIG. 4 Another preferred embodiment of a gas supply system 12 according to the invention is shown in FIG. 4. Analogous to the embodiment in FIG. For this purpose, each valve 5 is connected to a plurality of injectors 3 via injector supply lines 6 . Otherwise, the embodiment of FIG. 4 can be designed in the same way as the embodiment of FIG.
