New machining strategies for a hollow camshaft

The camshaft is used to open the intake and exhaust valves according to the design timing. The shaft rotates around its own axis – this rotary movement is repeatedly converted into a short longitudinal movement by the cams mounted on it.

Use of cold forming for optimum results

This Felss camshaft was developed together with a customer and was the first time that active cylinder management was implemented in a large-scale production four-cylinder engine. When less power is required, the vehicle’s active cylinder management system therefore automatically switches to a mode in which only two cylinders operate. This automatically increases efficiency and reduces fuel consumption. On average, the car saves 15% on gasoline.

Special features of the realized solution

  • Greater degrees of forming without the use of heat-based processes
  • Fuel savings in the application thanks to the option of individual cylinder deactivation
  • More precise toothing and material hardening through work hardening
  • Suitable for series production through the use of proven processes
