How Many Parts Does a Car Have?
1 Answers
Because different categories of cars have completely different numbers of parts. It is estimated that a typical passenger car 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 as many as 20,000. Cars: Generally divided into four basic parts: the engine, chassis, body, and electronic-electrical equipment. Among these, 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). The transmission system: mainly consists of the clutch, gearbox, universal joint, drive shaft, and drive axle. The car body primarily serves to protect the driver and create a good aerodynamic environment. Car body structure: In terms of form, car body structures are mainly divided into body-on-frame, unibody, and semi-unibody. Car body components include the engine hood, roof, trunk lid, fenders, front apron, etc. Automotive electronics: Electronics refer to the collective term for vehicle electronic control devices and onboard automotive electronic control devices. Vehicle 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. The main purposes of cleaning car parts are to remove oil stains, carbon deposits, and scale. Liquid flow cleaning method: The essence of the liquid flow cleaning method is to use the cleaning fluid to exert mechanical, thermal, and physicochemical effects on the dirt on the part's surface, causing it to detach from the part's surface and achieve the cleaning purpose. Steam cleaning method: The essence of the steam cleaning method is to use steam at a temperature of 90~100°C and a pressure of 0.5~2MPa to clean the dirt on the surface of parts. This method requires specialized steam equipment and supporting systems, involving significant investment and higher costs. This method is suitable for cleaning parts with severe oil stains that are difficult to clean with general cleaning methods. The steam cleaning method involves high-temperature and high-pressure operations, requiring appropriate labor protection equipment. If not properly managed, the splashing of high-temperature and high-pressure steam during cleaning can easily cause injuries to the operator.
