Abstract:
An apparatus for coupling laser light into a combustion chamber of a combustion engine includes a combustion chamber window and a structural element, wherein the combustion chamber window is releasably fixable to the structural element, wherein there is provided an optical window which is arranged at the structural element and is at least region-wise covered by the combustion chamber window.
Abstract:
The invention relates to a device for igniting a fuel/air mixture in the combustion chamber of an internal combustion engine. The device includes an electrode which is connected to a voltage source and extends into a precombustion chamber, and the precombustion chamber is separated at least in some regions from the combustion chamber by a wall. A control device or a regulating device is provided which controls the voltage supply to the electrode such that a corona discharge is carried out in the precombustion chamber. The wall has at least one opening for exchanging fluids between the combustion chamber and precombustion chamber, and a fluid inlet opens into the precombustion chamber.

Abstract:
A laser spark plug, in particular for an internal combustion engine, having an arrangement or structure for coupling, especially focusing, laser radiation in or on an ignition point, including an arrangement or structure for influencing a fluid flow disposed in an end region of the laser spark plug on the side of the combustion chamber, which constitute an essentially sleeve-shaped extension of the laser spark plug in the direction of the combustion chamber, in which the arrangement or structure for influencing the fluid flow is configured to influence the fluid flow in the region of the ignition point.
Abstract:
A laser spark plug includes a laser light-producing device and a spark plug housing at the end of which facing the combustion chamber an injection lens for injecting laser light into the combustion chamber of an internal combustion engine is arranged. The spark plug housing includes a fastening zone for fastening the laser spark plug in a cylinder head of the internal combustion engine. A projection on the end of the spark plug housing facing the combustion chamber houses the injection lens. The outer diameter (D1) of the projection is smaller in the area of the injection lens than the outer diameter (D2) of the spark plug housing in the fastening zone.
Abstract:
A spark plug of an internal combustion engine, in particular for use in Otto-cycle gas engines, comprising an insulator body, a base central electrode, at least one ground electrode and at least one swirl chamber, wherein the electrodes of the spark plug are surrounded by a wall, which in particular is in the form of a surface of a cylinder, of the swirl chamber, wherein at least one ground electrode carrier arrangement (8) with a plurality of inwardly facing, preferably flat ground electrodes (9) or a plurality of ground electrode carriers (6) each with inwardly facing, preferably flat ground electrodes (9) is or are arranged at the wall (13) of the swirl chamber (3).
Abstract:
A laser ignition plug, comprising a pumped light source and a longitudinally pumped laser resonator, which are each arranged in the housing of the laser ignition plug, characterized by a cooling air inlet, a cooling air outlet and a cooling region connecting the cooling air inlet with the cooling air outlet, wherein the cooling region is surrounding the pumped light source at least in certain sectors.
Abstract:
The invention relates to an arrangement including an internal combustion engine ignition device having a spark plug and a spark plug seat (in which the spark plug can be fastened in a fastening zone), and a cylinder head in which the spark plug is or can be mounted via the spark plug seat. The cylinder head has a cylinder head cooling cavity. The spark plug seat includes a temperature control medium chamber which is separate from the cylinder head cooling cavity and has a cooling medium feed line and a cooling medium discharge line. The temperature control medium chamber and the cylinder head cooling cavity are connected to separate medium temperature control devices and form separate medium systems.
Abstract:
A laser ignition apparatus including at least two laser light generating devices and a common optical coupling-in means for coupling laser light from the at least two laser light generating devices into a combustion chamber of a combustion machine, wherein the at least two laser light generating devices are so arranged that laser light given off by the laser light generating devices in the operating condition impinges on the optical coupling-in means and/or issues from the optical coupling-in means in parallel displaced relationship or at an angle to each other. A method of igniting a fuel/air mixture in a combustion chamber of a combustion machine.
