Multispecies Laser Diagnostic System for Vehicle Tailpipe Emission Measurements

Autor: Luigi Biondo, Oliver Diemel, Vadim Doberstein, Henrik Gerken, Lars Illmann, Michael Jonek, Marvin Schmidt, Tim Steinhaus, Steven Wagner

A multispecies in situ TDLAS-system for simultaneous detection of NO, CO, CO2, H2O and NH3 was applied at an engine test rig for exhaust gas measurements and results were compared to commercially available reference systems.

Multi-Parameter IC Engine Exhaust Gas Diagnostics - From Manifold, Via Aftertreatment to the Tail Pipe End

Autor: Johannes Emmert, Lisa Engel, Anna Schmidt, Steven Wagner, Niels Göran Blume, Felix Stritzke, Luigi Biondo, Oliver Diemel

Publikováno v: Imaging and Applied Optics 2018 (3D, AO, AIO, COSI, DH, IS, LACSEA, LS&C, MATH, pcAOP).

More stringent exhaust emissions regulation of IC engines requires more detailed investigation of the aftertreatment and conversion processes of the exhaust flow. Here, we present three independent laser absorption spectrometers for the measurement o

TDLAS-based NH3 mole fraction measurement for exhaust diagnostics during selective catalytic reduction using a fiber-coupled 2.2-µm DFB diode laser

Autor: Felix Stritzke, Steven Wagner, Oliver Diemel

Publikováno v: Applied Physics B. 119:143-152

A new developed tunable diode laser spectrometer for the measurement of ammonia (NH3) mole fractions in exhaust gas matrices with strong CO2 and H2O background at temperatures up to 800 K is presented. In situ diagnostics in harsh exhaust environment

An interband cascade laser-based in situ absorption sensor for nitric oxide in combustion exhaust gases

Autor: Andreas Dreizler, Jhon Pareja, Oliver Diemel, Steven Wagner

Publikováno v: Applied Physics B. 123

A direct absorption nitric oxide sensor for combustion exhaust gas measurements, based on an interband cascade laser operating at 5.2 µm, is presented. The sensor was applied to the hot air co-flow of an auto-ignition test rig (800–1300 K), which

NO mole fraction measurement in a plasma-heated auto ignition test rig using a 5.2 µm interband cascade laser

Autor: Oliver Diemel, Jhon Pareja, Steven Wagner, Andreas Dreizler

Publikováno v: Imaging and Applied Optics 2016.

In-situ concentration measurements of nitric oxide in the microwave-plasma-heated turbulent air-co-flow (800-1300 K) of an auto-ignition test rig have been performed, employing tunable diode laser absorption spectroscopy at a wavelength of 5.2 μm.
