Oily blow-by gases out of the crankcase affect the life time of parts of the engine and of the intake as well as the emission of a motor vehicle. The determination of the performance of oil mist separator systems is complex, as they depend on the operation point of the engine operation map. Well-established gravimetric methods for the characterization of oil mist emissions provide comparatively pour information in spite of high costs.
With the use of the inline measuring method of Topas, it is possible to collect complete engine operation maps in less than one day by combining it with an intelligent gravimetric procedure.
