In modern development processes, measurement and simulation are increasingly merging together to form a single unit. In response to this trend, the Virtual Vehicle Research Centre has developed a tool and applied for a patent that can combine friction measurements with simulation of the crankcase bearings. This new development method allows precise analysis of engine friction over the entire characteristic map.

Multitude of Individual Optimisations

The entanglement of an innovative measurement technique with an accurate simulation yields in total a powerful tool to investigate the friction power losses in engines under realistic operating conditions, as will be discussed in the following. While the total engine friction power losses and the friction of the valve train are measured experimentally, the friction power losses of the crank train journal bearings are calculated using simulation. The result is in an efficient and powerful determination of the individual engine subassemblies...
