Thanks to the uninterrupted grain flow, the Felss torsional vibration absorbers offer high stability and excellent surface quality.
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.
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.
Weight of the shaft reduced from 5.2 to 3.3 kg.
Ten times the fatigue strength of conventionally produced components.
15 % lower fuel consumption.
Highest Precision: Production tolerance of 1/10 mm.
