What is the difference between Volkswagen engines CSS and EA211?

[CodyMarie]

CSS and DJS are both part of the EA211 series, distinguished by emission standards after the implementation of China VI. CSS complies with China V, while DJS meets China VI standards. Here are the relevant introductions to CSS and EA211: 1. CSS is a cost-reduction strategy for engines, where each cylinder has a fixed displacement, such as 0.4L. For example, a three-cylinder engine would be 1.2L, and a four-cylinder engine would be 1.6L. This strategy allows different displacement engine platforms to share more component assemblies, expanding machining scale and the demand for other common parts, thereby reducing the overall cost of the engine platform. 2. EA211 is a newly developed 1.4T turbocharged engine under the Volkswagen MQB modular transverse platform. It features an all-aluminum cylinder block, making the entire engine lighter in weight.
