Volkswagen Might Develop a Cylinder Deactivation System for 1.4-liter Engines

One of the most talked-about engine technology in the automotive industry today is the cylinder deactivation one. The VW Group recently joined the list of carmakers that offer this, announcing it for its upcoming Audi S6, S7 and S8 models.

However, it seems that the Germans are considering taking the concept even further. You, see, until now, it has been announced for vehicles with V8 engines, but VW engineers want to use it for a future 1.4-liter TSI four-pot unit that will debut on the seventh generation of the Golf, allowing the compact to offer impressive efficiency figures.

When power isn't needed, the engine will only use two cylinders, thus offering increased efficiency, with the cycle due to be used 1,400 and 4,000 rpm.

Neither the deactivation itself nor the fuel efficiency increase are the problem, However, the process has to be almost imperceptible to the driver, and this is where the most engineering efforts are needed.

The systems monitors parameters such as the throttle pedal's position, engine load, accessories usage level and others in order to switch between the two- and four-cylinder modes.

However, all this is still only a rumor, so we can't go too far yet. Should the development make it into production, we expect to see it on multiple VW Group models that use this engine, such as the VW Polo and the Audi A1.
