Cooperation project PTB-AVL „Generating diesel and propane soot by diffusion flames and comparing their applicability as calibration aerosols analogous to engine combustion processes“


The cooperation of PTB and AVL-List GmbH – one of the world’s largest manufacturers of measurement instruments for the automotive sector – continued this year with further experiments at the diesel soot generator at PTB. Stability and reproducibility of the diesel soot generator were further improved. New operating points were determined, which are suitable to model the motoric soot emissions at roller test benches concerning size and chemical composition (OC/EC ratio) of the soot particles.
