How Many Major Systems Does a Car Have?
1 Answers
Cars are divided into five major systems: the fuel supply system, the starting system, the cooling system, the lubrication system, and the ignition system. Below are their respective introductions: Fuel Supply System: Composed of the air intake, fuel supply system, and electronic control system. It prepares a certain quantity and concentration of the air-fuel mixture according to the engine's requirements, supplies it to the cylinders, and expels the exhaust gases from the cylinders into the atmosphere. Starting System: Composed of the battery, starting control and transmission mechanism, and starter. The process from when the crankshaft begins to rotate under external force until the engine starts to idle automatically is called engine starting. The devices required to complete this process are collectively referred to as the engine starting system. Cooling System: Composed of the water pump, radiator, fan, water jacket, and thermostat. It dissipates part of the heat absorbed by the heated components in a timely manner. Lubrication System: Composed of the oil pump, oil filter, oil cooler, and oil strainer. It delivers a certain amount of clean lubricating oil to the surfaces of moving parts to achieve liquid friction, reduce frictional resistance, minimize wear on components, and clean and cool the surfaces of the parts. Ignition System: Composed of the battery, generator, ignition coil, distributor, and spark plug. 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 spark plug electrodes at the right time.
