Abstract:
Recent developments in engine technologies and exhaust aftertreatment systems significantly reduced the particle emissions of diesel engines. This also demands new measurement devices for the periodical emission checks, which shall ensure unchanged low emissions over the vehicles’ lifetime. As the current light transmission technique has reached its detection limit, a new device based on light scattering is presented. This paper gives a short overview of scattering theory, followed by a description of the measurement system. An emphasis is placed on the control mechanism for achieving a stable light source. Furthermore first measurement results are presented. Finally the issue of correlation between scattering and established measures is discussed.
