This Felss camshaft has active cylinder management for the first time: when less power is required, the vehicle changes to a mode in which only two cylinders work.
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.
