摘要:
A spark plug is described, for an internal combustion engine, having a prechamber for accommodating an ignitable medium, and having a laser device for applying laser radiation to an ignition point situated in the prechamber. The laser device has a laser-active solid body having a passive Q-switch.
摘要:
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.

摘要:
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.

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.

摘要:
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.
