One of the most widely adopted LI methods is nanosecond laser-induced spark ignition (ns-LISI), in which combustible mixtures undergo multiphoton ionization followed by avalanche breakdown, resulting in high-temperature and high-pressure plasma along with shockwaves. However, inevitable shot-to-shot energy fluctuations resulting from ns light sources lead to the stochastic nature of the breakdown, influencing reaction routes and producing potential misfiring.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2021-03-robust-ultralow-energy-threshold-ignition-fuels-ultrashort-pulsed.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Robust and ultralow-energy-threshold ignition of lean fuels by an ultrashort-pulsed laser<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Laser ignition (LI) is a promising electrode-less alternative to electronic spark ignition of lean fuel\/air mixtures, offering high thermal efficiency with low harmful emissions.
