Five-Valve Technology
The amount of fuel that can be effectively combusted in the cylinder influences an engine's performance. A direct gauge of this performance is the volume of air that can reach the cylinders. In this context, five-valve technology offers crucial advantages: engines with five valves per cylinder can be supplied with air better and faster. This boosts torque and power output. Fuel consumption and emission levels are also improved. Volkswagen was one of the first car manufacturers to mass-produce engines with five valves per cylinder.
