The basic systems of an automobile can be divided into four major categories: power, chassis, body, and electronics, with each system working together to ensure the vehicle's operation. The power system is centered on the engine and includes the fuel supply system (fuel tank, fuel pump, fuel injectors, etc.), starting system (battery, starter), cooling system (water pump, radiator), and lubrication system (oil pump, oil filter). Petrol engines require an ignition system (spark plugs, ignition coils), while diesel engines do not. The chassis system covers the transmission system (clutch, transmission, drive shaft), running system (suspension, wheels), steering system (steering wheel, steering gear), and braking system (brake pedal, brakes), ensuring power transmission and control safety. The coolant needs to be replaced every two years and cannot be replaced with water; regular maintenance of the lubrication system can significantly extend the engine's service life; modern electronic ignition systems have generally replaced traditional mechanical structures, improving reliability.
