What are the common engine layout types for regular family sedans?

[OEsther]

Regular family sedans typically adopt four types of engine layouts, namely L-type, V-type, H-type, and W-type. Below are their respective introductions: L-type engine: Inline (Line Engine) engines refer to cylinders arranged in a straight line, where all cylinders are aligned side by side at the same angle within a single plane. V-type engine: This layout divides all cylinders into two groups, positioning adjacent cylinders at a certain angle to each other, forming two planes with an included angle. Viewed from the side, the cylinders appear in a V-shape. H-type engine: Commonly known as the horizontally opposed engine, this is also a variant of the V-type engine. By expanding the angle of the V-engine to 180°, adjacent cylinders are positioned opposite each other, creating a horizontally opposed configuration. These are typically 4-cylinder or 6-cylinder engines. W-type engine: This represents Volkswagen Group's proprietary engine technology. Essentially, it combines two V-type engines to form another V-type engine, following the principle "V + V = W = V".
