Laser igniter with integral optimal geometry prechamber
Abstract
A laser igniter that avoids autoignition and soot formation within the prechamber and will minimize the formation of Nitrogen Oxides (NO.sub.x). The laser igniter has a laser spark plug with a microlaser and a prechamber integrally formed with the laser spark plug. The prechamber has six nozzle holes with three of the nozzle holes having a large diameter and three of the nozzle holes having a small diameter. The large and small nozzle holes are in a staggered arrangement.
