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

Författare

Summary, in English

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.
