Optimized multiple laser ignition plug
Abstract:
An ignition device for an internal combustion engine includes optical focusing lenses, including a center optical focusing lens and satellite optical focusing lens. The center optical focusing lens focuses laser light from a laser generator to a center ignition point in a combustion chamber of a cylinder of the internal combustion engine. The satellite optical focusing lenses focus laser light from the laser generator to satellite ignition points in the combustion chamber of the cylinder of the internal combustion engine. The satellite optical focusing lenses are directionally angled away from the center optical focusing lens. A firing depth of the center ignition point is greater than a firing depth of the at least one satellite ignition point.
