The oil emission of a combustion engine has a direct influence on CO2 and particulate emissions. In order to determine oil emission caused specifically by the piston group, part of the exhaust gas flow is taken and analyzed using a mass spectrometer directly downstream of the exhaust valve in the exhaust manifold…

Since the oil emission in transient engine operation shows significant deviations from the stationary operation maps, one focus is the analysis of the dynamic oil emission behavior. This means that the calculation and assessment of dynamic oil measurement operations and the calculation of a standardized test program for the visualization of dynamic oil emission effects and for the systematic investigation of the causing oil transport mechanisms.

Optimisation of lube oil consumption in transient engine operation is gaining increasing attention from engine developers. Engine operation in extended stop-and-go phases can sporadically lead to unexpected oil consumption problems for inner-city driving.
