Because different categories of cars have completely different numbers of parts. It is estimated that an average sedan is assembled from over 10,000 non-detachable independent parts. For structurally complex custom cars, such as F1 race cars, the number of independent parts can reach up to 20,000. Below is an introduction to car parts: 1. Car: Generally divided into four basic parts: the engine, chassis, body, and electronic/electrical equipment. The engine is the power unit of the car, mainly composed of the engine block, crankshaft-connecting rod mechanism, valve train, cooling system, lubrication system, fuel system, and ignition system (diesel engines do not have an ignition system). 2. Transmission system: Mainly composed of the clutch, gearbox, universal joint, drive shaft, and drive axle. The car body's primary function is to protect the driver and create an optimal aerodynamic environment. 3. Car body structure: In terms of form, car body structures are mainly divided into body-on-frame, unibody, and semi-unibody. The car body components include the hood, roof panel, trunk lid, fender, front bulkhead, etc. 4. Automotive electronics: Automotive electronics is the general term for vehicle body electronic control devices and onboard automotive electronic control devices. Vehicle body electronic control devices include the engine control system, chassis control system, and body electronic control system. These are all electronic control systems composed of sensors, microprocessors (MPU), actuators, and dozens or even hundreds of electronic components and parts.
