At the lower end of the engine-speed scale, the intake valves are opened later, which improves idling quality and smoothness. At moderate engine speeds, the intake valves open much earlier, which boosts torque and permits exhaust gas re-circulation inside the combustion chambers, reducing fuel consumption and exhaust emissions. Finally, at high engine speeds, intake valve opening is once again delayed, so that full power can be developed. VANOS operates on the intake camshaft in accordance with engine speed and accelerator pedal position. VANOS significantly enhances emission management, increases output and torque, and offer better fuel economy. The latest version of VANOS is double-VANOS, used, among others, in the new M3. The VANOS system is based on an adjustment mechanism that can modify the position of the intake camshaft versus the crankshaft. Double-VANOS adds an .... Get the whole story right here in this video.
