Measurement techniques for piston ring rotation, engine oil emission and blow by have been imple- mented on a single-cylinder petrol engine. A novel method […]Read More Publication SAE: Real-Time Measurement of the Piston Ring Gap Positions and Their Effect on Exhaust Engine Oil Emission
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…
