Application of Two-Photon Laser-Induced Fluorescence for Single-Shot Visualization of Carbon Monoxide in a Spark Ignited Engine

Volume 61, Number 1 (Jan. 2007) Page 1-5

Richter, M.; Li, Z.S.; Aldén, M.

Carbon monoxide detection through the use of two-photon laser-induced fluorescence (LIF) has been investigated for engine diagnostics applications. Two-dimensional single-shot LIF imaging of CO was achieved in a spark ignited (SI) engine. The interference from C2 and photolysis of hot CO2 was found to be negligible through the spectrally and spatially resolved measurements.
