- Hydraulic Cam Phaser Pressure Boosting at Low Engine Oil Pressure
Stored pressurized oil and a pressure-controlled cylinder help a hydraulic cam phaser shift quickly at low engine oil pressure.
- Cam Phaser Oil Pressure Boosting for Fast Valve Timing Shift
Stored high-pressure oil from an accumulator and pressure-controlled cylinder speeds cam phasing at low engine speed while cutting pump losses.
