DuoPhase - Twin Output Actuator Upgrade for DuoCam

Description

A hydraulic actuator with twin outputs. When coupled with a DuoCam it can be used to provide independent phasing of intake and exhaust valves on a single camshaft.

Technical Benefits

  • Reduced NOx emissions - via Warm Up (EEVO) and Keep Warm (LIVC) strategies.
  • Reduced CO2 emissions - For exhaust thermal management (compared to a fuel post injection strategy)
  • Miller cycle - retarding the cam lobe for just one intake valve of a cylinder pair to give effective variable duration
  • Improved fuel economy
  • Increased torque and power

General Application Benefits

  • Delivers the functionality of DOHC with VVT on a single cam with low investment costs
  • Integration - Retains Existing OHC / OHV architectures for simple implementation
  • Reliable - Mechanical valvetrains that use known and well proven technologies
  • Conventional valvetrain layout - Low design and manufacturing investment to integrate
  • Low friction - conventional roller followers, no additional hydraulic pumping losses
  • Simple Controls - same requirements as a conventional DOHC hydraulic cam phaser system controlled by the engines ECU
  • Continuously Variable - simple calibration. Direct positional feedback for OBD
