All the details of the new 1.5 TSI of VW-Audi, which introduces the variable geometry Turbo

Volkswagen-Audi presents its new generation of petrol engines EA211 evo. The new family of petrol engines aims to become an important step forward in the Volkswagen Group carrying far beyond the technology of thrusters supercharged driven by gasoline. The idea of the future continues to telescoping in a word, downsizing, but Volkswagen and Audi seem to have done your homework, betting on new technologies and leading to the petrol engines to a significant improvement in efficiency and performance. Let’s see how they have achieved this.

A 10% more efficient, with up to 150 HP and designed for all types of applications… even in plug-in hybrids

In full scandal for the emissions associated with diesel engines, Volkswagen, will, no doubt, that bet by the innovation in petrol engines seems to be a smart move. The Diesel has the days counted in the U.S. and Europe, and that is a reality that is palpable to-day-to-day for much AdBlue is added to the combustion chambers of the engines turbo. That said, the Volkswagen Group is planning a renovation of all engines 1.4 TSI and 1.8 TSI engine for the new 1.5 TSI belonging to the generation EA 211 evo. This replacement will be staggered, so that during the first few months is likely to accompany different generations of propellant gas.

The starting point of the engines EA211 evo is based on the improvement of the thermal performance of the thruster, an idea that Volkswagen has pursued the integration of different innovations. To begin with we find the use of Miller cycle with compression ratios of 12.5:1, new thermal treatments on the internal elements for to reduce friction losses (atmospheric plasma spray), unveils a new generation of direct injection of gasoline with up to 350 bars pressure, lubrication system and cooling smart, the evolution of the system ACT to the cylinder deactivation… but the great novelty is the introduction of a series of turbochargers with variable geometry.

why is Turbos with variable geometry on a petrol engine?

we have Already tested the Porsche 718 Boxster S, the second Porsche use Turbos VTG in gasoline-engines

The arrival of the Turbos VTG (variable geometry) is a milestone in production models in series. Although they are well known in diesel engines, Porsche was the first manufacturer to bring the Turbos VTG to gasoline-engines in the Porsche 911 Turbo, expanding its use in the new Porsche Boxster S that we have already tested. But now the thing changes, and that is Volkswagen speaking of hundreds of thousands of petrol engines supercharged by making use of this type of turbochargers. According to Volkswagen, the use of this type of technology has been possible thanks to the deep work done in the design of the exhaust system that reaches peaks of 880º. With the right materials and a controlled temperature, the new 1.5 TSI Turbocharged, VTG should not give problems, offering a more progressive, with better torque figures and lower emissions.

the arrival of The new 1.5 TSI is very close to

The new EA211 evo promise to mark differences with respect to the competition

The new engines belonging to the generation EA211 evo will be available in different configurations. On the one hand we will see mechanical 1,000 cc in versions atmospheric and supercharged and always with 3 cylinders. But the big novelty will be the 1.5 TSI with 4-cylinder versions with power outputs of 130 and 150 HP, although with the possibility of reaching the 200 HP in a second stage so as to relieve the 1.8 TSI which moves to models like the Volkswagen Polo GTI and SEAT Ibiza Cupra.

Although Volkswagen has not reported any deadlines for the arrival into the markets of this new generation of engines, everything points to throughout this year we will meet the first arrivals of the new 1.5 TSI engine under the bonnets of best seller manufacturer: Volkswagen Golf, Audi A3, Seat Leon and Skoda Octavia.
