Laser ignition system

摘要

In a laser ignition system (2) for igniting fuel sprayed into a combustion chamber, comprising a laser beam generating source (4) coupled to an optical fiber (8) to transmit the beam into the chamber, the coupling system includes a coupling lens (8) for focusing the beam at a point upstream of the fiber, a source-fiber connector (17) and a device (16) for keeping the fiber inlet section straight, downstream of the connector and extending a specific distance along the fiber.
