Using a methodology that combines the potential of real test bench investigations and virtual simulations, Virtual Vehicle has determined the friction conditions in various combustion engines. The detailed tribology comparison between two gasoline engines and a diesel engine shows the differences in both concept and engine.

Selection of the Engines

In this article, a novel approach developed by Virtual Vehicle as a combination of friction test bench measurements with an accurate friction bearing simulation for friction loss determination and assignment will be applied to engines from three different concepts. This enables a detailed friction loss analysis for the engine sub- assemblies not only in motored conditions but especially at load conditions. The main principles of the so-called virtual strip-down friction analysis has already been presented in MTZ (for further information see [1, 2, 3]). The selection of the investigated engines was done specifically to be able to compare...
