Laser vibrometry has taken a firm place in the automotive sector over the past few years. This non-contact measuring process is used at Porsche Engineering to investigate and improve the dynamic behavior of the valve train during engine development.

The requirements for modern valve train mechanisms – whether for cars, motorcycles, small or industrial engines – are becoming increasingly complex. The case study of VarioCam Plus illustrates the expertise acquired by Porsche Engineering through the development and application of highperformance engines for its parent company.
