What is the Technical Principle of an Engine?

[BlakelyLee]

Engine technology principle is that the intake valve opens, the exhaust valve closes, the piston moves from the top dead center to the bottom dead center, the cylinder volume above the piston increases, creating a vacuum, the pressure inside the cylinder drops below the intake pressure, and under the vacuum suction, the gasoline atomized by the carburetor or fuel injection device mixes with air to form a combustible mixture, which is sucked into the cylinder through the intake passage and intake valve. The intake process continues until the piston passes the bottom dead center and the intake valve closes. Then the upward-moving piston begins to compress the gas. Below is an introduction to the engine: Meaning of the engine: An engine is a machine that can convert other forms of energy into mechanical energy. Classification of engines: Internal combustion engines, external combustion engines (such as Stirling engines, steam engines, etc.), jet engines, electric motors, etc. Composition of the engine: The main components of the engine body include the cylinder block, cylinder liner, cylinder head, and cylinder gasket.
