Volkswagen presents its new engine 1.5 TSI 130 and 150 HP

Volkswagen TSI EA211 evoVolkswagen has presented at the International Symposium of the Engine of Vienna which will be its new family of engines EA211 TSI evo of gasoline. The German group has presented a new four-cylinder engine 1.5 TSI in versions 130 and 150 HP that is the first member of this new range of engines that will come to the models from the Volkswagen Group this same 2016.

This engine is called to replace the 1.4 TSI 125 and 150 hp, and as expected, a better performance, lower intakes and emissions under are the main characteristics of the first of the engines EA211 TSI evo. Comparing it with the 1.4 TSI of 125 CV, Volkswagen promises a fuel consumption of gasoline up to 10% lower.

The new 1.5 TSI 130 HP offers 200 Nm of torque between 1,300 and 4,000 revolutions

many Are the novelties introduced by the Volkswagen in this new engine 1.5 TSI. It uses a propeller Miller cycle with a compression ratio of 12.5:1, while at the same time using a variable geometry turbo (up to now, were of fixed geometry engines TSI) and a direct injection system at high pressure. The thermal management and friction inside the engine have been optimized and all the versions of this engine have with the disconnect selective cylinders to reduce the power consumption in driving low load, by making the intake and exhaust valves of cylinders two and three and the injection to stop working.

To improve the thermal management, the engine reaches its operating temperature in less time, which helps to avoid wear and tear and mechanical to reduce the fuel consumption, while improving the comfort since the heat can go into operation in a shorter time. The reduction of the friction of the engine are achieved by using advanced materials in the areas of friction and using a low viscosity oil 0W20 that is sent to all parts of the engine by an oil pump of variable flow.

The use of a variable geometry turbo has undeniable advantages in the performance of the new engine 1.5 TSI. The inertia of the turbocharger is lower and that means that the turbo can be loaded before, and to provide more torque from low revolutions. In fact, the maximum torque is obtained only up to 1,300 revolutions. The intercooler has also been relocated and is now larger, so that it can cool more and better the air that finally enter the engine.
