An internal combustion engine is a power machine, and is a heat engine that directly converts heat energy emitted by burning fuel in the machine into power. The internal combustion engine in the broad sense includes not only reciprocating piston, rotary piston and free piston engines but also jet engines of the rotary vane type, but the internal combustion engine is generally referred to as a piston engine. Piston internal combustion engines are the most common of the reciprocating piston types. Piston internal combustion engines mix fuel and air and combust the mixture in their cylinders, and the released heat energy causes the cylinders to produce high temperature, high pressure combustion gases. The gas expands to drive the piston to do work, and then the mechanical work is output through a crank-link mechanism or other mechanisms to drive the driven machinery to work. Common diesel engines and gasoline engines convert internal energy into mechanical energy, and change the internal energy by doing work, and crankshaft connecting rod mechanisms are main moving parts for realizing working cycle of the engines and completing energy conversion.
