Definitions

  • This laser ignition comprises an ignition laser, which projects into the combustion chamber of an internal combustion engine.
  • the ignition laser is optically pumped by a light source from a pump light source.
  • combustion chamber window is present, which is transmissive to the laser beams generated in the ignition laser.
  • This combustion chamber window must be sealingly received in a housing of the ignition laser. High demands are placed on the seal between the combustion chamber window and the housing because surface temperatures of over 600 ° C. can occur on the combustion chamber window during operation of the internal combustion engine. In addition, intermittent pressure loads of more than 250 bar are added. If a firing laser is used to ignite a gas turbine, although lower pressures prevail in the combustion chamber of the gas turbine, but the surface of the combustion chamber window can reach temperatures of up to 1,000 ° C, in any case, uncontrolled Glühzünditch must be prevented.
  • the invention is based on the object to provide an ignition laser in which the combustion chamber window and the housing are sealed so that over the entire life of the engine and the pressure prevailing in the combustion chamber of an internal combustion engine and temperatures safe and reliable sealing of the combustion chamber window and housing is guaranteed.
  • an ignition laser for an internal combustion engine comprising a laser-active solid, a combustion chamber window and a housing achieved in that the housing and the combustion chamber windows are at least indirectly connected to one another cohesively.
  • the material-tight connection of housing and combustion chamber window according to the invention ensures the required tightness even at the highest pressures and temperatures. It is important to ensure that the part of the housing, which is materially connected to the combustion chamber window, a similar thermal expansion coefficient as the combustion chamber window has. As a result, the thermal stresses are reduced and as a result, the life and reliability of the cohesive connection between the housing and the combustion chamber window increases.
  • the membrane and / or the intermediate ring it is recommended to use materials whose thermal expansion coefficient substantially corresponds to that of the combustion chamber window.
  • the material Pernifer 2198 MS from Thyssen VDM is particularly suitable for this purpose.
  • the inner sleeve, the membrane and / or the intermediate ring from a ductile material, preferably nickel or copper.
  • a ductile material preferably nickel or copper.
  • a heat-resistant material preferably made of steel of type 1.4913, has proven.
  • the cohesive connection between the housing, membrane, intermediate ring and combustion chamber window can be achieved by brazing, soldering, welding, gluing, in particular by means of ceramic and / or metallic adhesive, or vitrification.
  • solder In order to achieve a good connection between solder and combustion chamber window during soldering, it is important that the surface of the combustion chamber window is wetted. This can be done by metallizing, for example via the so-called W / Mn method, the Mo / Mn method, the vapor deposition by CVD (Chemical Vapor Deposition) or PVD (Physical Vapor Deposition), ion plating and / or active soldering. In active soldering, the solder contains at least one surface-active element, such as titanium.
  • a glass solder is possible; advantageous with a silver-glass composition.
  • Such glass solders are offered and sold, for example, by Schott and Ferro.
  • the silver acts inter alia as a ductile material, so that materials can be joined together, the coefficient of thermal expansion is different.
  • solders which have a comparatively low soldering temperature in order to reduce the thermal stresses that arise during cooling.
  • the solder must withstand the temperatures occurring during operation.
  • the joint between the housing and the combustion chamber window is preferably arranged on the side of the combustion chamber window facing away from the combustion chamber of the internal combustion engine. It is alternatively also possible to provide a joint on both sides of the combustion chamber window. This results in a redundancy of the seal and thus increased security against the loss of function of the seal.
  • combustion chamber window and the housing are not to be materially sealed but to be sealed by pressing, it has proven to be advantageous to provide a coating of a ductile material, preferably of copper, in the region of the sealing surface. If this coating consists, for example, of copper, this becomes ductile due to the high surface pressure and operating temperatures between the combustion chamber window and housing in the region of the sealing surface and thus fills the roughness of the combustion chamber window and housing in the region of the sealing surface. This ensures a durable and reliable seal.
  • a ductile material preferably of copper
  • the thickness of this coating can be between 5 .mu.m and 100 .mu.m and preferably applied by electroplating.
  • the outer sleeve has a shoulder at its end facing the combustion chamber, this shoulder partially covering the combustion chamber window.
  • the outer sleeve and the inner sleeve can be bonded together in a prestressed state.
  • the biasing force of the screw can be influenced within wide limits.
  • the methods of (Dehn) -screw calculation can be used.
  • the outer sleeve may have a region in which a controlled elongation occurs, while the inner sleeve is compressed in the region between the sealing surface and bolt thread by the biasing force. This results in a "softer" screw, which in particular has a positive effect on the sealing force even at changing temperatures.

  • the pumping light source 30 is controlled by a control unit 32, which also controls the injector 18.
  • the pumping light source 30 feeds a plurality of optical fiber devices 28 for different ignition lasers 26, which are each assigned to a cylinder 12 of the internal combustion engine 10.
  • the pumping light source 30 has a plurality of individual laser light sources 340, which are connected to a pulse power supply 36.
  • a "stationary" distribution of pump light to the various laser devices 26 is realized, so that no optical distributors or the like between the pump light source 30 and the ignition lasers 26 are required.
  • the ignition laser 26 has, for example, a laser-active solid 44 with a passive Q-switching circuit 46, which forms an optical resonator together with a coupling mirror 42 and a Auskoppelapt 48.
  • the ignition laser 26 Upon application of a pumping light generated by the pumping light source 30, the ignition laser 26 generates a laser pulse 24 in a manner known per se, which is directed by a focusing optics 52 onto one in the combustion chamber 14 (FIG. FIG. 1a ) located ignition point ZP is focused.

  • the housing 38 preferably has a thermal expansion coefficient corresponding to the coefficient of thermal expansion of the combustion chamber window 58. As a result, thermal stresses are avoided and as a result, the joint 60 relieved. At the same time, however, make sure that the housing 38 is made of a heat-resistant material. And as a result, also has a sufficient fatigue strength at the prevailing operating temperatures in the combustion chamber. Particularly advantageous in this embodiment is their low space requirement.
  • FIG. 3 is a further embodiment of a compound according to the invention between the combustion chamber window 58 and housing 38 also shown in partial longitudinal section.
  • the housing 38 is formed in two parts. It comprises an inner sleeve 62 and an outer sleeve 64.
  • the outer sleeve 64 has at a combustion chamber 14 (see FIG. 1a ) facing a paragraph 66 on.
  • the paragraph 66 has essentially two functions. First, it shields a portion of the combustion chamber window 58 from the combustion chamber and the pressures and temperatures prevailing there, so that the thermal load of the combustion chamber window 58 is reduced.

  • the material of the outer sleeve 64 can be optimized in terms of heat resistance and fatigue strength, while the material of the inner sleeve 62 is selected so that its thermal expansion coefficient as much as possible Thermal expansion coefficient corresponds to the combustion chamber window 58. As a result, the thermal stresses are reduced and the joint 60 relieved.
  • a sealing surface 70 is formed between the shoulder 66 and the combustion chamber window, which thus represents a redundant seal, which to a certain extent precedes the joint 60 and thereby either already completely separates the combustion chamber 14 and the interior of the ignition laser 26 causes or at least reduces the temperature and pressure stress of the joint 60 and as a result, the joint 60 relieved.
  • the shoulder 66 or the combustion chamber window 58 with the area of the sealing surface 70 with a coating of a ductile material, such as copper.
