The Advancements in the EA 211 evo2 Engine
Volkswagen’s latest iteration of the 1.5 TSI engine, known as evo2, brings forth significant improvements in efficiency and emission control. The engineers have managed to enhance the engine’s emission control system by integrating the three-way catalytic converter and petrol particulate filter closer to the engine in a single module. This design not only boosts efficiency but also reduces the use of precious metals during production, laying a strong foundation for meeting upcoming emission standards.
One of the standout features contributing to reduced fuel consumption in the 1.5 TSI evo2 is the upgraded Active Cylinder Management system, ACTplus. Developed jointly by Volkswagen’s Wolfsburg and Salzgitter sites, this system focuses on enhancing the activation and deactivation of cylinders to ensure seamless engine operation. With ACTplus, the second and third cylinders are deactivated during low and medium loads and speeds, resulting in enhanced efficiency without compromising performance.
Complementing these advancements, the 1.5 TSI evo2 engine boasts a variable-geometry turbocharger, a high-pressure injection system reaching pressures of up to 350 bar, plasma-coated cylinder walls to reduce friction, and pistons with cast-in cooling ducts for optimized combustion and increased efficiency.
Looking Towards the Future
The TSI evo2 engines are built to accommodate fuels derived from renewable sources, positioning them well to meet future environmental requirements. Furthermore, these engines are adaptable to various levels of hybridization, enabling a system power of up to 200 kW (272 PS) with a plug-in concept.
As part of Volkswagen’s ACCELERATE strategy towards achieving zero emissions, the company is pushing ahead with its electrification plans. By 2030, Volkswagen aims for electric models to constitute 70% of its sales. Simultaneously, the brand continues to enhance its combustion engines to comply with upcoming global emission standards like Euro 7, catering to markets where electric mobility is still in its nascent stages.
The Legacy of the EA 211 Family
The compact TSI engines from the EA 211 family have been global bestsellers since 2012, blending high-tech features with lightweight construction. Volkswagen produces over four million of these engines annually across eleven locations worldwide, showcasing their widespread popularity and reliability over the past decade.
