Definitions
- the invention relates to a laser spark plug, in particular for an internal combustion engine of a motor vehicle.
- Such a laser spark plug is known for example from DE 10 2006 018 973
- the known laser spark plug has an integrated prechamber arrangement, in which the prechamber is formed integrally with the housing of the laser spark plug.
- the disadvantage here always the entire laser spark plug must be replaced together with the integrated pre-chamber, if only one component of the known arrangement no longer works.
- the service life of the antechamber as a result of deposits and other wear can be lower than the service life of the laser components also integrated into the laser spark plug.
- a still functioning laser assembly must be exchanged and disposed of together with the already worn integrated pre-chamber arrangement, which is uneconomical in particular because of the - relative to the pre-chamber components - much higher manufacturing costs of the laser arrangement.
- the inventive design of the laser spark plug allows a providence of a separate pre-chamber module, which can be advantageously connected by virtue of the connecting means according to the invention only in a relatively late stage of production with the laser spark plug.
- the connecting means are designed such that they permit a detachable connection of the laser spark plug to the prechamber module.
- the prechamber module can be connected to the laser spark plug and, if necessary, also be separated again from the laser spark plug. In particular, it is thereby possible, when reaching a wear limit of the prechamber module that non-destructive of the
- the still functioning laser spark plug with its laser arrangement can be advantageously used further and for this purpose, for example, connected via the connecting means according to the invention with a new pre-chamber module.
- the connecting means are designed such that they allow a screw connection and / or a snap-fit connection of the laser spark plug to the prechamber module, which ensures a particularly simple interchangeability of the prechamber module.
- Laser spark plug extending, preferably tubular, mounting portion, which is preferably formed integrally with a housing of the laser spark plug.
- the attachment portion may, for example, an internal thread and / or a
- the prechamber module can be arranged either within the attachment portion or can be screwed in the manner of a throw over the mounting portion of the laser spark plug.
- a first prechamber module is e.g. is arranged by means of the internal thread of the fastening portion in the tubular mounting portion, and of which a second pre-chamber module is screwed as a cap onto the external thread of the fastening portion.
- a second pre-chamber module is screwed as a cap onto the external thread of the fastening portion.
- an antechamber module e.g. also an optical component such as e.g. a combustion chamber window or a focusing optics are screwed into the tubular mounting portion, provided that it has corresponding, with the connecting means of the laser spark plug cooperating connecting means.
- an optical component such as e.g. a combustion chamber window or a focusing optics
- Vorschmodul for a laser spark plug has connecting means, which are formed to cooperate with the connecting means of the laser spark plug. This may in particular be an internal or external thread and / or means for producing a press fit and / or a latching connection.
- the prechamber module has a material with high thermal conductivity, in particular brass.
- a composite material which contains, for example, copper and steel.
- a homogeneous design of the pre-chamber module of one of the aforementioned materials is also possible.
- the material selection according to the invention for the prechamber module advantageously brings about improved heat dissipation or distribution, so that in particular the combustion chamber side surface temperature of the prechamber module is reduced, whereby the risk of uncontrolled pre-ignition is reduced.
- pre-chamber module has a, preferably arranged on the outside, driving profile, in particular a hexagonal profile.
- the entrainment profile can preferably be arranged in a combustion chamber-facing end region of the prechamber module.
- Prechamber module is provided at least one overflow channel, which allows fluid communication between an inner region and an outer region of the pre-chamber module.
- the pre-chamber module according to the invention may also have further openings, which allow a fluid exchange between the interior of the pre-chamber module and a combustion chamber surrounding the pre-chamber module of an internal combustion engine.
- the pre-chamber module according to the invention may advantageously also have an integrated optical component, such as, for example, a combustion chamber window designed as a sacrificial window. Because of the simple interchangeability of the pre-chamber module, a "spent" sacrificial window for the laser spark plug can thus also be changed easily, in particular without having to exchange the components permanently integrated in the laser spark plug combustion chamber window.
- At least one optical component in particular a combustion chamber window, can be arranged in the region of the connecting means between the prechamber module and the end region of the laser spark plug facing the combustion chamber and can be fixed by means of the prechamber module with respect to the laser spark plug.
- Case serves the invention replaceable pre-chamber module at the same time as a mounting means for holding the optical component.
- sealing means and suitable enclosures for receiving the optical component in the region of the connecting means may be provided in this variant of the invention, for example
