A seminar was organized by
CCRC on “Laser-induced
multi-point ignition for enabling high-performance engines” by Dr. Suk Ho
Chung.
Dr.
Suk Ho Chung, Named professor of Mechanical Engineering at CCRC, introduced a
new technique of laser-induced cavity ignition and laser-induced multi-point
ignition.
An ignition system for
future engines should be reliable and efficient to enhance combustion
stability, since ignition not only initiates combustion but also influences
subsequent combustion. With mixtures that are lean or diluted with exhaust
gases, the ignition system has a critical influence on misfire or
cycle-to-cycle variation.
He talked about how non-conventional ignition
techniques such as laser-induced ignition have become an attractive field of
research in order to replace the conventional electrical discharge system. It
has been suggested that if flames are initiated simultaneously at multiple
locations when laser is used as an ignition source, efficient combustion can be
achieved and total combustion time can be reduced significantly compared to
that using a single-point ignition.
