Description

Technical Field

[0002] An internal combustion engine is a power machine. It is a heat engine that burns fuel inside the machine and converts the heat energy released directly into power. In a broad sense, internal combustion engines include not only reciprocating piston internal combustion engines, rotary piston engines and free piston engines, but also rotary impeller jet engines, but the internal combustion engine usually refers to a piston internal combustion engine. The reciprocating piston type is the most common piston internal combustion engine. The piston internal combustion engine mixes fuel and air and burns them in its cylinder. The heat energy released generates high-temperature and high-pressure combustion gas in the cylinder. The expansion of the combustion gas pushes the piston to work, and then the mechanical work is output through the crank-connecting rod mechanism or other mechanisms to drive the driven machine to work. Common ones include diesel engines and gasoline engines, which convert internal energy into mechanical energy, that is, changing internal energy by doing work.

[0003] When the internal combustion engine casing is processed, in order to ensure the installation precision of its internal equipment, the accuracy of the internal combustion engine casing processing must be ensured. However, in the prior art, most internal combustion engine casings are processed only by positioning them using a lathe in conjunction with manual measuring equipment, which affects the positioning effect during the internal combustion engine casing processing and reduces the accuracy of the internal combustion engine casing processing.
