    • Formaldehyde (CH2O) is an important intermediate species in combustion processes and it can through laser-induced fluorescence measurements be used for instantaneous flame front detection. The present study has focussed on the use of the third harmonic of a Nd:YAG laser at 355 nm as excitation wavelength for formaldehyde, and different dimethyl ether (C2H6O) flames were used as sources of formaldehyde in the experiments. The investigations included studies of the overlap between the laser profile and the absorption lines of formaldehyde, saturation effects and the potential occurrence of laser-induced photochemistry. The technique was applied for detection of formaldehyde in an internal combustion engine operated both as a spark ignition engine and as a homogenous charge compression ignition engine.

  • The effect to knock on the heat transfer in a spark-ignition engines : Cars temperature measurements in the thermal boundary layer combined with heat-flux measurements
  • 2000
  • Ingår i: SAE Technical Papers. ; :B, s. 79-79
  • Tidskriftsartikel (refereegranskat)abstract
    • The temperature in the thermal boundary layer close to the combustion chamber wall was measured under knocking and non-knocking conditions using dual-broadband rotational coherent anti-Stokes Raman Scattering (CARS). A horseshoe-shaped combustion extension was employed to get an optical access to the region near the combustion chamber wall. Time-resolved measurements of the cylinder pressure (at three different locations in the cylinder chamber) and the heat flux to the wall were conducted simultaneously with the CARS measurements. Knocking and non-knocking conditions were achieved using different mixtures of n-heptane and iso-octane. Results from this measurement series will be used further for comparison with modeling of heat transfer and chemical kinetics close to the cylinder wall.
