Classified by displacement: In the same brand, the engine models of different displacements may be different. For example, the engine models of Audi A4 1.8T and 2.0T are different. 3. Classified by engine structure: There are many types of engine structures, including common in-line four-cylinder (L4) engines, V-type six-cylinder (V6) engines, horizontally opposed four-cylinder (F4) engines, W-type engines, etc. Engine models are generally named according to different types.
