Audi valvelift system

More power and torque combined with less fuel consumption – this is what every engine designer strives to achieve. The Audi valvelift system (AVS) has brought Audi a great deal closer to this goal.

Audi uses two versions of this innovative technology. On the V6 FSI engines with 2.8 and 3.2 litres of displacement, it acts on the intake valves. In this case, it regulates the amount of intake air by adjusting the lift in two stages for opening and closing the valves. The throttle can usually remain wide open – throttle losses, i.e. reduced efficiency when air is drawn in against resistance from the closed throttle, are largely eliminated. The engine is able to breathe freely, and achieves higher output and torque in combination with low fuel consumption.
On the 2.0 TFSI, AVS acts on the exhaust side. By means of specific valve timing, the amount of fresh air in the cylinders can be significantly increased with the turbocharger, particularly in the lower engine speed range. This is because the exhaust gases are expelled faster and flow to the turbocharger is improved. This results in more torque, even more dynamic response and thus a substantial increase in pulling power. The system thus offers the driver appreciably more driving pleasure. In addition, AVS permits longer gear ratios, achieving a considerable reduction in fuel consumption.
