Intake Camshaft CVVT Pulley S60 Parts 8642284 For S80 V70 XC70

Variable Valve Timing (VVT): Auto camshaft adjustment systems often fall under the category of Variable Valve Timing (VVT) technology. VVT systems enable the adjustment of valve timing, duration, or lift to optimize engine performance throughout the engine's operating range.

Actuation Mechanism: The auto camshaft adjustment system utilizes various mechanisms to alter the timing of the intake camshaft. These mechanisms can include hydraulic actuators, oil pressure-controlled valves, or electronically controlled solenoids. The system receives signals from the engine control unit (ECU) to adjust the camshaft timing as needed.

Benefits: By adjusting the timing of the intake valves, the auto camshaft adjustment system can improve engine efficiency and performance in multiple ways:

At low engine speeds, the system can delay the opening of the intake valves, resulting in better torque and smoother idling.

During high engine speeds or under heavy load, the system can advance the intake valve timing for increased power output.

It can optimize the air-fuel mixture by adjusting valve timing to enhance combustion efficiency and reduce emissions.
