Internal Combustion Engine Motion Mechanism

Internal combustion engine is a type of power machinery. It is a thermodynamic engine that converts the thermal energy released from burning fuel inside the machine directly into power.

In a broad sense, internal combustion engines include reciprocating piston internal combustion engines, rotary piston engines, and free-piston engines, as well as rotary impeller-type jet engines. However, the term “internal combustion engine” usually refers to piston internal combustion engines.

Among piston internal combustion engines, the reciprocating piston type is the most common. Piston internal combustion engines mix fuel with air, burn it within the cylinder, and the released thermal energy generates high-temperature and high-pressure gas in the cylinder. The gas expands and pushes the piston to perform work, and this mechanical work is then output through a crankshaft and connecting rod mechanism or other mechanisms to drive driven machinery.
