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
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 causes of pre-ignition in the gasoline engine are still not fully understood because of the complexity of the influencing factors and the complex interactions of the countless processes involved. As studies show, engine oil also has an influence on the formation of pre-ignition. A module is delivered to view the phenomenon holistically and to optimize the corresponding processes on the production engine.

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…

Turbocharging is one of the key technologies in current and future engine development. Due to the increasing requirements that extend beyond power output and torque alone, the internal and external mechanical components of turbochargers are being subjected to an ever-increasing load spectrum.

The structural design of the piston group has a considerable influence on the mechanical losses of internal combustion engines. However, measures to reduce friction are often in conflict with the oil consumption – especially when designing the tangential force of the oil control ring.
