Title: Method and system to distribute high-energy pulses to multiple channels

Patent ·
OSTI ID:1531630
; ;

A method and system to distribute high-power laser pulses to create sparks in individual cylinders of a multi-cylinder engine are provided. A laser provides laser output pulses. A distributor includes a linear array of mirrors with a respective mirror associated with one of the laser plugs. Each mirror is operatively controlled to move into a laser beam path to direct individual laser output pulses the associated laser plug for providing spark generation. The system enables correct cylinder firing order for predefined multi-cylinder firing sequences and allows for individual cylinder timing variation.
