Techniques for Detecting Flame Arrival in Premixed-Charge Spark Ignition Engines

摘要: Experimental techniques for detecting the arrival of a freely propagating flame at specified locations within and walls combustion volume are reviewed. The methods discussed all fast, real-time capable cycle-resolved measurements necessary to study premixed-charge in spark ignition engines. one non-optical technique is ionization probe, which detects single point. optical include laser beam refraction, direct imaging situ fibers, line-of-sight techniques.
