Modern vehicles contain a multitude of networked electronics. This feature causes distributed functions in distributed electronics. Malfunctions occurring during EMC testing cannot be allocated precisely without detailed knowledge of the data streams. The electromagnetic environment during EMC-testing limits the possibilities of using standard solutions to detect these malfunctions. The paper will present a new tool, which is able to track the data streams in a CAN-Bus system during EMC-testing. By integrating EMC related parameters in the existing data stream of the vehicle's data bus, it is possible to keep a record of malfunctions as they occur.

The vibration-generating mechanisms inside an engine are highly non-linear (combustion, valve operation, hydraulic bearing behavior, etc.). However, the engine structure, under the influence of these vibration-generating mechanisms, responds in a highly linear way. For the development and optimization of the engine structure for noise and vibration it is beneficial to use fast and ‘simple’ linear models, like linear FE-models, measured modal models or measured FRF-models. All these models allow a qualitative assessment of variants without excitation information. But, for true optimization, internal excitation spectra are needed in order to avoid that effort is spent to optimize non-critical system properties. Unfortunately, these internal excitation spectra are difficult to measure. Direct measurement of combustion pressure is still feasible, but crank-bearing forces, piston guidance forces etc. can only be identified indirectly.
