Definitions
- the invention relates to a device and a method for providing a fuel-air mixture of air and a cryogenic fuel, in particular cryogenic hydrogen, for an internal combustion engine with at least one luftbeaufschlagbaren inlet channel and at least one assigned thereto injector with nozzle for injecting the cryogenic fuel.
- cryogenic fuel such as cryogenic hydrogen
- the cryogenic fuel is usually supplied by means of an injector, as is apparent from DE 100 60 786 A1, for example.
- an injector which results in the problem that due to the injection of the cryogenic fuel, the nozzle of the injector cools below the freezing point of water. On the cold surface, water vapor from the intake air accumulates in the form of frost.
- This Eisstromrung leads to restrictions in the operation of the internal combustion engine to the complete freezing of the injector and thus to the failure of the internal combustion engine.
- the cryogenic fuel impinges on the opposite side of the inlet channel to the injector. Due to the intensive contact with the cold fuel, this surface is cooled below the freezing point of water, so that here also deposits ice. This ice layer leads to an impairment of the inlet cross-section.
- the intake air is cooled in several stages, dehumidified to a final temperature level before cooling, and the low-temperature fuel is supplied to the dehumidified intake air.
- the object of the invention is therefore to further develop a device and a method mentioned above, so that in a simplified manner, icing of the injector nozzle and / or the inlet channel is prevented and the advantages of the cryogenic mixture formation are maintained.
- the solution of this object is achieved with a device having the features of claim 1, wherein according to the invention the nozzle is at least partially heated and with a method having the features of claim 7, wherein according to the invention the nozzle is at least partially heated.
- precipitation of atmospheric moisture is effectively prevented, especially in icing-prone areas of the injector or the inlet channel, at the same time is limited to a minimum only in some areas heating the heat input into the cold fuel.
- the invention thus makes it possible to exploit the advantages of the cryogenic mixture formation on the internal combustion engine operation in terms of power, emission and efficiency and at the same time avoids icing in the mixture formation range. In this case, an implementation of the invention requires only a small effort.
- contact of the cryogenic fuel with heated nozzle areas is temporally and locally limited. This avoids excessive heating of the cold fuel as well as measures for thermal decoupling of the fuel supply from the heated nozzle.
- waste heat of the internal combustion engine can be used for passive heating of the nozzle.
- a guide for the targeted beam guidance of the cryogenic fuel is provided in the inlet channel. This is - optionally in conjunction with an oblique to the inlet duct longitudinal axis arrangement of the injector - a targeted beam guidance of the cryogenic fuel in the inlet channel allows so that the cold fuel jet is isolated by an air jacket of the warmer inlet duct wall or the warm cylinder head and heat input into the fuel is minimized.
- cryogenic fuel is brought into contact with only a partial region of the heated region of the nozzle to avoid excessive heating and / or is conducted past heated regions of the nozzle at a high flow velocity.
- waste heat of the internal combustion engine is used for passive heating of the nozzle.
- to minimize the heat input of the jet of cryogenic fuel in the inlet channel is at least partially centrally isolated with an air jacket against the engine.
- the figure shows a detail of an internal combustion engine 102 with a combustion chamber 108 and a cylinder head 104.
- the combustion chamber 108 has an inlet 110 which can be closed by means of a valve 12. Via the inlet 110, the combustion chamber 108 of the internal combustion engine 102 can be filled with a combustible fuel-air mixture during its operation.
- the inlet 110 is associated with an inlet channel 106, the outlet side opens into the combustion chamber 108. On the inlet side of the inlet channel 106 can be acted upon with air.
- an injector 114 For injection of fuel into the inlet air flow, an injector 114 is provided which comprises a nozzle 116 on the outlet side.
- the injector is inclined with respect to the longitudinal axis of the intake passage so that the nozzle 116 comes close to the flange 105 to the warm cylinder head 104 in operation, without the average distance between the cold operating injector 114 and the cylinder head 104 warm compared to a conventional arrangement is reduced.
- the injector 1 14 is mounted in the cryogenic mixture formation unit 124. This is made of heat-insulating material to minimize the heat input into the injector 1 14.
- a guide plate 118 is arranged, which is thermally well connected to the cylinder head 104 and therefore heat-treated during operation of the internal combustion engine 102. Opposite the fuel supply line, the guide plate 118 is thermally insulated.
- the baffle 1 18 is made of a highly thermally conductive material, such as aluminum, and is attached to the inner wall of the inlet channel 106 around the nozzle 116 of the injector 114 around.
- the guide plate 118 forms a nozzle directed in the flow direction of the inlet air flow.
- Deep-freeze hydrogen stored in the vehicle in a liquid state is applied to the injector 114 via a feed line.
- the injector 114 actuated by a control device, so that a predetermined volume flow of fuel via the nozzle 116 exits.
- the cold fuel stream 120 impinges on the baffle 118, which thermally engages the warm cylinder head 104 connected is. As a result, a cooling below the freezing point of water is avoided and an accumulation of moisture from the air flowing through the inlet channel 106 air in the form of frost or ice effectively prevented.
- the fuel jet 122 From the guide plate 1 18 of the fuel jet 122 flows radially spreading in the flow direction of the intake air flow.
- the fuel jet 122 is guided in particular close to the nozzle so that an air layer remains between the fuel jet 122 and the inlet channel wall, which causes an insulation with respect to the inlet channel wall.
- accumulation of moisture from the air flowing in through the inlet channel 106 in the form of frost or ice on the inlet channel wall is effectively prevented.
- the fuel stream fans out, mixes with air and heats up.
- baffle 118 With the baffle 118 on the one hand, a derivative of cold from the fuel supplied and a dissipation of heat from the cylinder head, on the other hand so that the fuel flow is injected centrally at least partially insulated with an air jacket against the inlet wall in the inlet air stream.
