Fuel injection valve has integrated or connected laser ignition arrangement with channel in continuous optical contact with split point of optical conductor or other split optical coupling point

摘要

The device has an integrated or connected laser ignition device with a channel (5,8,11,20) in continuous optical contact with an optical conductor splitting point (6) or a further split optical coupling point in its injector upper part (7), injector housing (10) and nozzle body (13) or in a mechanical extension. The device has solid or liquid or colloidal optical conductors and angle-varying focusing optical elements at the laser output point.
