Volkswagen Implements Cylinder Deactivation On Four Cylinder Engine

Volkswagen is presenting another Polo in the model’s range: the Polo BlueGT.

A technical highlight of the Polo BlueGT is its TSI engine with active cylinder management (ACT) – which automatically shuts off two of the engine’s four cylinders. Other companies have included cylinder deactivation in six and eight cylinder engines, but Volkswagen is the first manufacturer to implement such a system in a four-cylinder engine.

According to Volkswagen, by temporarily deactivating the second and third cylinders under low to medium load states, fuel consumption in the EU driving cycle is reduced by about 0.4 l/100 km. When driven at a constant speed of 50 kph in third or fourth gear, it is possible to save up to 1.0 l/100 km in fuel.

The torque-friendly 1.4-liter TSI fitted to the Polo BlueGT develops a power output of 138 horsepower, and has a combined fuel consumption of 51 mph (4.6 l/100 km). When the Polo BlueGT is ordered with the optional 7-speed DSG transmission, fuel consumption is further reduced to 52 mpg (4.5 l/100 km)

The Polo BlueGT combines many fuel saving measures on top of ACT, like downsizing (reduced engine displacement plus direct injection and charging) and the company’s BlueMotion Technologies (Stop/Start system, battery regeneration, aerodynamic components).

The new car launches onto the market in the fourth quarter of this year. Its base price in Germany will be19,650 euros including VAT.

The original Polo made its debut in 1975; and shortly after launch, it quickly became a bestseller. To date, nearly 13 million units of the little Volkswagen have been built.

Milestones of the series include models such as the Polo BlueMotion and sports models such as the Polo G40 and the Polo GTI.

    Some truly great content on this internet site, thank you for contribution. Get the facts You actually make it appear really easy together with your presentation but I find this matter to be actually one thing that I feel I might by no means understand. It seems too complex and extremely large for me. I’m looking ahead to your subsequent submit, I’ll attempt to get the hold of it!
