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.

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 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 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.

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 investigation of the lubricating oil balance at the piston group and its influencing variables are an important contribution to optimizing future engine concepts in terms of consumption and emissions. At the Institute for Internal Combustion Engines of the Technical University of Munich, a novel engine was developed as part of the FVV project “piston ring oil transport 1″…
