Summary

With the introduction of the new modular transverse platform, Volkswagen also undertook a fundamental rework of its engine platforms. As part of that process, the highly successful EA111 series of small four-cylinder TSI engines has been completely renewed in order to achieve the optimum basis from which to meet future demands in vehicle packaging, emissions and CO2 pollution, as well as modularity. Systematic aluminium lightweight construction with four valve technology and an exhaust manifold integrated into the cylinder head form the technical heart of the new EA211 engine generation. For ongoing optimization of friction characteristics, the new TSI engines feature a toothed belt drive and a monolithic valve train module with roller bearings. The engines are based on a carefully tiered, tribologically optimized system platform.
