Basic structure of internal combustion engines
Overview The engine body is the framework that constitutes the engine, serving as the foundation for the installation of various mechanisms and systems. It is equipped with all the main components and accessories of the engine, both inside and outside, and bears various loads. Therefore, the body must have sufficient strength and stiffness. The body assembly is mainly composed of parts such as cylinder block, cylinder sleeve, cylinder head, and cylinder gasket.

Basic parameters of internal combustion engines
displacement First, let's take a look at the most common engine parameter - engine displacement. The engine displacement is the total working volume of each cylinder in the engine, usually expressed in liters (L). The working volume of a cylinder refers to the volume of gas swept by the piston from top dead center to bottom dead center, also known as the single cylinder displacement, which depends on the cylinder diameter and piston stroke. Engine displacement is a very important engine parameter, which better represents the size of the engine than cylinder diameter and number. Many indicators of the engine are closely related to the displacement. Generally speaking, the larger the displacement, the greater the engine output power.
