What is the significance of Volkswagen's 2.0T low-power engine?

[DelLane]

Volkswagen's choice of the 2.0T low-power version engine is significant because it offers higher cost performance and better meets current consumer demands. The current usage status of engines and the advantages of low-power engines are as follows: Current usage status of engines: Volkswagen has gradually phased out the 1.8T engine, replacing it with the 2.0T low-power version. As of now, apart from Skoda which still retains the 1.8T engine, both Volkswagen and Audi series have established product differentiation between high and low-power 2.0T engines. Advantages of low-power engines: The high-power EA888-Gen3 uses the traditional Otto cycle, while the low-power EA888-Gen3B employs the Miller cycle. The former has a very traditional structure with equal compression and expansion ratios, requiring no complex valve timing mechanisms. In contrast, the Miller cycle is more similar to the Atkinson cycle, achieving an expansion ratio greater than the compression ratio by closing the intake valve early. This enhances efficiency under low-load conditions, in simpler terms, making it more fuel-efficient.
