Top : Schematics of ignition by (a) a spark plug and (b), (c) a laser. (c) Bottom : Schlieren photographs for early stage of ignition in a constant-volume chamber ignited by (a) spark plug and (b) micro-laser in a stoichiometric mixture. Spark plugs can ignite leaner fuel mixtures, but only by increasing spark energy.
