Volkswagen to introduce TSI evo2 engine in Europe

Volkswagen is set to launch the latest-generation TSI evo2 engine in Europe. The German automotive brand said that the enhanced 1.5 TSI gasoline powerplant makes it possible to reduce both fuel consumption and CO2 emissions, allowing would-be-equipped models to offer an ideal combination of high efficiency and powerful performance.

According to the Wolfsburg-based car company, its engineers have moved the three-way catalytic converter and gasoline particulate filter close to the engine in a single emission control module, thereby further improving the efficiency of the emission control system. By doing so, the TSI evo2 engines permit reduced use of precious metals in production and at the same time create the basis for compliance with future emission standards.

“The 1.5 TSI is a key pillar of the Volkswagen engine range because it powers many models worldwide, from the T-Cross3 through to the Passat Variant. We have continuously enhanced the compact four-cylinder unit. It now offers significant fuel consumption benefits and a very dynamic response,” said VW Member of the Board of Management Thomas Ulbrich.

A key technological feature that allows the TSI evo2 engine to enjoy reduced fuel consumption is its enhanced Active Cylinder Management system, ACTplus — a joint development of VW’s Wolfsburg and Salzgitter sites.

“The highlights of the latest version include Active Cylinder Management ACTplus, an emission control module close to the engine, and the modern TSI-Evo combustion process,” Ulbrich said.

Through ACTplus, VW was able to optimize the combustion process in two-cylinder operation. The second and third cylinders are not fired when the engine is operating at low and medium loads and speeds. The efficiency, Volkswagen said, is increased in the active cylinders while the middle cylinders simply follow with practically no losses — they are reactivated when the accelerator is pressed again.

Alongside the variable-geometry turbocharger, the 1.5 TSI also features other high-tech components: the high-pressure injection system generates a pressure of up to 350 bar, plasma-coated cylinder walls reduce friction, and pistons with cast-in cooling ducts allow combustion to be optimized and efficiency increased.

Per VW, the compact, ultra-modern four-cylinder engine will initially be available with an output of around 148hp with more variants of the 1.5 TSI evo2 to follow.

In Europe, the T-Roc and T-Roc Cabriolet will be the first models to be delivered with the new engine. The TSI evo2 will also be introduced successively in other models by the end of the year.
