What are the major systems that make up a car?

[DeBrianna]

A car consists of five major systems: 1. Fuel supply system: According to the requirements of the engine, it prepares a certain quantity and concentration of the air-fuel mixture to be supplied into the cylinder and exhausts the burned gases from the cylinder into the atmosphere; 2. Lubrication system: It delivers a specific amount of clean lubricating oil to the surfaces of moving parts to achieve liquid friction, reduce frictional resistance, minimize wear of components, and clean and cool the surfaces of parts; 3. Cooling system: It dissipates part of the heat absorbed by heated components in a timely manner; 4. Ignition system: The combustible mixture in the cylinder is ignited by an electric spark. The gasoline engine's cylinder head is equipped with a spark plug, the tip of which extends into the combustion chamber, capable of generating an electric spark between the electrodes at the right time; 5. Starting system: The process from when the crankshaft begins to rotate under external force until the engine starts to idle automatically is called engine starting. The device required to complete the starting process is called the engine's starting system.
