Affordable Material and New Processing Strategies

The camshaft serves the purpose of opening the input and output valves in accordance with design-related control times. In the process, the shaft rotates on its own axis and, as a result of the cams attached to it, this rotational movement is repeatedly converted into a short longitudinal movement.

Felss Camshaft

This Felss camshaft was developed together with a customers, and active cylinder management was realized in a large series four cylinder engine for the first time. When less power is required, the active cylinder management of the vehicle therefore changes automatically to a mode in which only two cylinders work. This automatically increases efficiency and reduces fuel consumption. The car thus saves 15 % fuel on average.
