Variable valve timing (VVT) stator

Variable valve timing (VVT) stator

Variable valve timing (VVT) is used to optimise the engine’s output and efficiency under all operating points to improve performance and reduce emissions.

The elements in a VVT system, the rotor and the stator, are typically of complex shape. The VVT stator consists of multiple parts with advanced geometry, which puts extremely high demands on dimensional accuracy.

Using Höganäs high-precision toolbox for tailored Fe+Cu+C mixes enhances productivity and enables considerable reduction in the total manufacturing cost due to a number of unique advantages.



Benefits of Höganäs’ solution for PM variable timing:

  • Better dimensional stability
  • High and uniform compacted densities
  • Facilitated machining
  • Reduced scrap levels
