Abstract (en)
[origin: US2015218976A1] An oscillating-motor camshaft adjuster which provides that, through software, camshaft alternating torque is utilized only in conditions where the torque is adequate and/or it is important to reduce flow consumption. If there is two step lift and the camshaft alternating torque is not adequate in low lift, software can position the spool to utilize some camshaft alternating torque while also tanking oil to speed up the phasing.
