Variable valve train

Camshafts and modules with stroke variability

Technical description

A variable valvetrain system increases efficiency of the internal combustion engine in wide map ranges. The axially displaceable cam packs are actuated by an electric actuator and switch reliably within one motor revolution.

Customer benefits / unique selling propositions

  • Mechanical stroke changeover of the valves by override control

  • Individual cylinder control by electromechanical actuator

  • Application-appropriate material use and reduced required materials due to assembled design

  • Secure cam positioning in end position by locking
