The ten core systems of an automobile include the power system, transmission system, running system, steering system, braking system, fuel supply system, lubrication system, cooling system, ignition system, and starting system. As the core, the power system converts the chemical energy of fuel into mechanical energy through the engine, encompassing subsystems such as fuel supply, intake and exhaust, and cooling. The transmission system transfers power to the drive wheels via components like the gearbox, clutch, and driveshaft to accommodate varying driving conditions. The steering system controls vehicle direction through the steering wheel and steering mechanism, with most modern models featuring electric power steering technology. The fuel supply system precisely regulates the air-fuel mixture, the lubrication system minimizes component wear through engine oil, the cooling system maintains optimal engine temperature, while the ignition system (for petrol engines) and starting system are responsible for igniting the air-fuel mixture and initiating engine operation, respectively. These systems work synergistically to deliver vehicle power output, handling stability, and safety performance. Although not classified as a standalone system, electrical and electronic equipment permeates all systems to enable monitoring and control functions, exemplifying the high integration of modern automobiles.
