Abstract
Due to the discussion about possible health risks caused by fine particles also the automotive industry has increasing interest about characterization of particles from the exhaust of internal combustion engines.
Using an ultra fast ten channel Transient Differential Mobility Particle Spectrometer for the purpose of acquiring number size distributions of aerosols from exhaust gas it was possible for the first time to investigate particle size distributions under transient driving conditions.
Besides effects of transient engine behavior on particle formation the influence of fuel composition is discussed.
