Title:
内燃機関のためのレーザ誘導式外部点火装置
Document Type and Number:
Japanese Patent JP5766280
Kind Code:
B2
Abstract:
A laser spark plug for an internal combustion engine includes at least one element for guiding, shaping and/or generating laser radiation, a combustion chamber window and a housing. The housing has, on the opposite side of the combustion chamber window from the element, an aperture for the passage of the laser radiation guided, shaped and/or generated by the element into a prechamber disposed at the end of the housing on the combustion chamber side. At least one overflow channel is provided for a fluid connection between an internal space of the prechamber and a combustion chamber surrounding the prechamber. When a fluid flows into the internal space of the prechamber through the overflow channel, a fluid flow is obtained that enters the interior of the aperture at a minimum angle ε, in particular measured with respect to the longitudinal axis of the laser spark plug, of 45°.
