What does the number of car cylinders mean?

[Kingston]

Car cylinder number refers to the number of cylinders in the engine. Common cylinder counts for car engines include 3, 4, 5, 6, 8, 10, and 12 cylinders. Engines with 5 or fewer cylinders mostly adopt an in-line arrangement, denoted by the letter L. Engines with 6 to 12 cylinders mostly adopt a V-shaped arrangement, meaning the cylinders are arranged in the shape of the letter V, which saves space. The cylinder block of an in-line engine is arranged in a straight line, making the structure relatively simple. The cylinder is the housing of the steam turbine. The main function of the cylinder is to separate the flow path of the steam turbine from the atmosphere, ensuring that steam completes the work process within the steam turbine. It also supports certain stationary components of the steam turbine, bearing their weight and the thermal stress caused by uneven axial and radial temperature distribution along the cylinder.
