原始语种摘要: Abstract(#br)An on-line measurement for the diesel engine NO x emission based on tunable diode laser absorption spectroscopy (TDLAS) technique is realized. Two absorption lines 1900.07059cm −1 and 1626.91952cm −1 are chosen for NO and NO 2 measurement. Two ICL inter-band cascade (ICL) lasers are used to measure NO and NO 2 separated. In this work, we use the TDLAS system to research the NO x emissions on a four-stroke four-cylinder diesel engine. Optical windows are installed on the exhaust pipe of the diesel engine symmetrical to realize the on-line measurement. The direct detection method is adopted in this work, which can avoid the effect from unknown concentration of particulate matter (PM) in the exhaust. The NO x emission characteristic under...
