VW Launches TSI Cylinder Shut-Off - Web Exclusive

Volkswagen’s latest efficiency technology, a cylinder shut-off system, will debut in Europe on the new 1.4-liter TSI engine from the start of 2012.

VW is the first manufacturer in the world to implement cylinder shut-off on a four-cylinder TSI engine in volume production. The primary goal of the system is to reduce fuel consumption by temporarily shutting off two of the four cylinders under low to medium loads.

The cylinder shut-off is claimed to reduce fuel consumption by 0.4 liters per 100 km in the NEDC driving cycle. When integrated with Start/Stop, which deactivates the engine in neutral gear, the savings adds up to about 0.6 l/100km. The greatest benefits of the technology are realized when driving at constant, moderate speeds. At 30mph, in third or fourth gear, savings amount to nearly 1 l/100km.

This new TSI will apparently meet the future EU6 emissions standard but VW is quick to point out that the efficiency does not affect comfort: even when running on two cylinders, the engine reportedly remains quiet and vibration-free. Cylinder shut-off is active whenever the 1.4 TSI is between 1400 and 4000rpm, and its torque is between 18-33 lb/ft. We’re told, this applies to almsot 70 per cent of the driving distance in the EU fuel economy driving cycle.

As soon as the driver presses the accelerator pedal sufficiently hard, cylinders 2 and 3 are reactivated imperceptibly.

The system takes its information from the accelerator pedal sensor to detect the mode of driving. If the driving exhibits a non-uniform pattern, shut-off is automatically suppressed.
