High pressures placed on the automotive producers demand rapid analysis, advanced development capabilities and high levels of precision achieved at lower development costs and shorter time from first designs to functional prototypes. Where mechanical items were traditionally verified through empirical testing, today tools such as FEA, MBS, EHD or CFD are in commonly used. The key to success is the flexibility of refining the method for support work or troubleshooting scenarios from the early project concept phase. This paper deals with CAE tools used for the valvetrain development process. Main focus is concern on valvetrain vibrations, cranktrain or timing mechanisms influences are also discussed. All simulation strategies are presented on diesel four-cylinder in-line engine.
