LASER IGNITOR PROVIDED WITH WARM-UP DEVICE

摘要

PROBLEM TO BE SOLVED: To provide technology for shortening warm-up time in a case where a laser oscillator is used for a laser ignitor. SOLUTION: This laser ignitor provided with a warm-up device is provided with the laser ignitor 35 including the laser oscillator 36 to radiate laser beam to mixture in a combustor on chamber 16 of an internal combustion engine for ignition, and an electric warm-up device 40 to heat the laser oscillator when actuation of the laser oscillator is started. Warm-up time for heating the laser oscillator by the warm-up device to make it ready for oscillation is shortened. COPYRIGHT: (C)2006,JPO&NCIPI
