The way engine cylinders are arranged is called engine configuration. In-line engines have the cylinders in a line. The design creates a simply cast engine block. In vehicles applications, the number of cylinders is normally from 2 up to 6. Usually, the cylinders are vertical. As the number of the cylinders increase, the length of the block and crankshaft can become a problem. One way to avoid this is with a V configuration. The design makes the engines block and cr
ankshaft shorter and more rigid. 发动机的布臵即发动机气缸的排列方式。 发动机缸体按直线排 列的即直列式，这种布臵使得发动机缸体结构简单。汽车发动机 一般为2~6缸，通常气缸是垂直放臵的，但气缸数量的增加会导 致缸体和曲轴的长度过大，解决问题的措施之一就是采用V型布 臵，这种布臵方式可以使发动机缸体和曲轴长度尺寸更短，从而 大大增加刚度。
The four basic cylinder arrangements of a diesel or gas-burning engine are: cylinder-in-line; V-arrangement and Flat.
