Engine born
The engine is the power source of a car. Most car engines are thermal power devices, abbreviated as thermal engines. A thermal engine converts the thermal energy generated by fuel combustion into mechanical energy through changes in the state of the working fluid. In 1876, German Nicolaus A. Otto invented a reciprocating piston four stroke gasoline engine based on atmospheric pressure engines. Due to the use of four strokes of intake, compression, power generation, and exhaust, the thermal efficiency of the engine has increased from 11% of atmospheric pressure engines to 14%, while the engine's mass has decreased by 70%.

What is the function of a car cylinder head
The function of a car cylinder head is to seal the upper part of the cylinder, form a combustion chamber, and serve as a support for the camshaft, rocker arm shaft, and intake and exhaust pipes, bearing the action of high temperature and high pressure gas. The cylinder head sucks air into the cylinder, and the spark plug ignites the combustible mixture, driving the piston to do work, and exhaust gas is discharged from the exhaust pipe.
