What is the maximum number of cylinders in an engine?

[LeonardoMarie]

12 cylinders. Common cylinder counts for automotive engines include 3, 4, 6, 8, 10, and 12 cylinders. Meaning of L4: L4 stands for inline 4-cylinder. The inline layout is the most widely used cylinder arrangement today, especially in engines with displacements below 2.5L. In this layout, all cylinders are aligned in the same angle and arranged in a single plane, sharing only one cylinder head. The engine block and crankshaft structure are relatively simple, resembling cylinders standing in a single file. Common cylinder counts: Specifically, common types include L3, L4, L5, and L6 (the number represents the cylinder count). The advantages of this layout include compact size, high stability, good low-speed torque characteristics, and lower fuel consumption, which also implies lower manufacturing costs.
