What are phasing cylinders?

Phasing cylinders are components used in automotive engines, particularly in variable valve timing (VVT) systems. They help optimize engine performance by adjusting the timing of the valve openings and closings, allowing for better efficiency, power output, and emissions control. By changing the phase of the camshaft relative to the crankshaft, phasing cylinders enable engines to adapt to different driving conditions. This technology enhances overall engine responsiveness and fuel economy.
