IAV in collaboration with Cummins performed real-time on-road oil consumption measurements with a Lubrisense. Published at the 5th international Motoren Kongress, February 2018.Read More Real-time on-road oil consumption measurement
On the background of the continuously changing statutory regulations, increasing customer requirements for efficiency and dynamic, as well as competition for market shares, the complexityin automotive engineering, with at the same time shorter development cycles, has dramatically increased. Near future emission regulations like the limitation of particle number for direct injection gasoline engines or the RDE…

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.

The oil emission of an internal combustion engine has a direct influence on the CO2 and particle emissions. As a result, the reduction of oil emissions, especially in the context of the stricter emission limits for the automotive industry, is increasingly becoming the focus of attention. To achieve this goal, a deeper understanding of the mechanism of action for the formation of oil emissions in internal combustion engines is necessary.

The measurement of oil consumption and the investigation of oil consumption mechanisms in combustion engines are subject to various research projects. Methods like drain and weight, or such using tracers like radioactive substances, sulphur dioxide or pyrene are often too slow or insensitive for dynamic engine test cycles…

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.
