New strategies for processing a hollow camshaft
The camshaft is used to open the intake and exhaust valves in accordance with the control times specified in the design. In this process, the shaft rotates about its own axis – the cams that are mounted on it repeatedly convert this rotary movement into a short longitudinal movement.
Use of cold forming for optimum results
This Felss camshaft was jointly developed together with a customer and this was the first time that active cylinder management had ever been implemented in a large-series four-cylinder engine. As a result, when less power is required, the vehicle’s active cylinder management automatically switches to a mode in which only two cylinders operate. This automatically increases efficiency and reduces fuel consumption, with the car achieving petrol savings of 15% on average.
