Function of four-cylinder engine valve: A four-cylinder engine, also known as a four-cylinder engine, is a machine that can convert one form of energy into another more useful energy. Generally, chemical energy is converted into mechanical energy. The main part of power is the cylinder, which is the power source of the whole car. The engine block of a four-cylinder engine is mainly composed of cylinder block, crankcase, cylinder head and cylinder gasket. 2. Basic principle of four-cylinder engine: The basic principle of four-cylinder engine is that when the combustion gas expands in a sealed cylinder, it pushes the piston to do work and converts the thermal energy of gasoline (diesel) into mechanical energy.
