激光诱导荧光测量汽油机换气中C2浓度
C2Concentration Measurement in the Exhaust Gas of a Gasoline Engine by Laser-induced Fluorescence
摘要
用XeCl激光泵浦染料激光器,激发汽油机换气中C2自由基3пu-3пgg带荧光谱,根据谱线强度,测量了换气中的C2浓度(～1017 cm-3)；同时研究了汽油机不同空燃比对C2浓度的影响。
Abstract
Carbon concentration( 1017 cm-3) in the exhaust gas of a gasoline engine was measured by means of fluorescence nitensities of C2 radical at 3пx→3пg transition induced by XeCl laser pumped dye laser. The effect of different air-fuel ratio on the C2 concentrationwas also studied.
