Advanced Cam Phasers

Our cam phasers have two outputs in a single compact unit.
They are:

  • Easier to package than two conventional single-output-phasers.
  • Ideal for Dual Independent cam phasing.
  • Can be used with our SCP camshafts.
  • Robust well-tested designs with proven durability.

Compare and contrast these three cam phasing strategies.

Dual Equal

A dual-equal phaser is quite limiting as intake and exhaust events are mechanically linked. Watch now

Duplex

Both cam phasing outputs are still linked, but this is now in a non-linear ratio.   This significantly improves flexibilty whilst still requiring only one control system. Watch now

Dual Independent

Total flexibility - intake and exhaust cam phase is fully independent Watch now

Cam Phasing Upgrade Path

An engine can be designed in such a way that simple part replacement will change the specification of the cam phaser.  It can then be protected for future upgrades by ensuring that any dual equal design fits with this strategy

The Twin Vane Phaser

PICTURE: Shows the internals of a twin-vane cam phaser especially the cam sprocket and the cavity plate along with one output set of vanes.
  • Dual-Independent cam phasing from a single unit.
  • Compact vane-type design.
  • Two control systems required, one for each camshaft.

Assembly Animation

See how a cam-in-block SCP camshaft assembles to our twin vane phaser for dual independent control. Watch now

The Duplex Phaser

PICTURE: The duplex cam phaser is able to control the cam phase of two outputs with one input. A complete phaser and camshaft is shown in this picture.
  • One control system controls the phase of two camshafts.
  • Both outputs mechanically linked.
  • Non-linear ratio between outputs.
