What is the difference between CSS and EA211?
2 Answers
The differences between CSS and EA211 are mainly reflected in the following aspects: 1. Quantification. The EA211 series engines are constructed entirely from aluminum material, from the valve cover at the top of the engine to the oil pan at the bottom, all made of aluminum alloy. This significantly reduces the weight compared to the previous EA111 series. 2. Fuel consumption. The biggest advantage of EA211 is its fuel efficiency, which benefits from its cylinder deactivation system. This technology primarily works by automatically shutting down the second and third cylinders when the engine is operating under medium to low load, thereby reducing fuel consumption. Compared to models without this technology, fuel consumption per 100 kilometers is reduced by approximately 0.4L. 3. Work efficiency. As one of the core technologies of Volkswagen's MQB modular platform, the EA211 engine features dual variable valve timing for both intake and exhaust, and its direct injection system uses a 5-hole injector with an increased injection pressure of up to 200bar. These technologies collectively enhance the engine's work efficiency to a certain extent. Here is some additional information about the EA211: The EA211 engine is a new series of automotive engines under Volkswagen, including both three-cylinder and four-cylinder products. The first model to be equipped with this engine series was the Volkswagen UP.
I've been driving a Volkswagen for several years. The EA211 and EA111 are two generations of engines with significant differences. The EA211 uses an all-aluminum cylinder block, which is much lighter than the cast iron of the EA111, resulting in noticeable weight reduction and benefiting fuel economy. The chain design has been improved, unlike the EA111 where the chain sometimes stretches, causing noise or maintenance issues. Friction loss is also reduced, lowering fuel consumption by about 5%, allowing you to drive dozens of kilometers more on a full tank in the city. Emissions are more environmentally friendly, meeting Euro 6 standards, and the engine runs quieter overall, with almost no noise at idle. Although the EA111 is durable, its technology is older, noisier, and may require more maintenance. Upgrading to the EA211 can really make daily driving much smoother.
