03 Classification
Vol.1
Classification 1: Source Channel
According to the source channel of auto parts, they can be divided into original parts, aftermarket parts, dismantled parts, refurbished parts, etc.
- Original parts (matching parts)
Original parts refer to the accessories used by automobile manufacturers when producing new cars. These accessories have the logo of the automobile manufacturer, a unified accessory number, and meet the specifications and standards of the original car manufacturing. They are also commonly called "matching parts". They not only have the logo of the automobile manufacturer, but also the trademark, factory name and detailed address information of the accessory manufacturer. Because they are produced by accessory suppliers who cooperate with the original automobile manufacturer, original parts can meet or exceed the requirements of the original car in terms of quality, performance and compatibility.
- Aftermarket parts (non-matching parts)
Aftermarket parts refer to accessories that have not been certified by the automobile manufacturer. These accessories are not used in the automobile assembly production line. The range of aftermarket parts is very wide, and may include high-quality substitutes produced by world-renowned brands, or some poor quality knockoff products. Therefore, the quality of aftermarket parts varies, and consumers need to pay special attention to brand and quality when choosing.
- Disassembled car parts
Disassembled car parts are original parts removed from scrapped or accident cars. Since they are removed from the actual vehicle, they are usually very compatible with the original car, but due to the use, the status of such parts may vary. Disassembled car parts are usually cheaper, but the service life and quality cannot be guaranteed.
- Refurbished parts
Refurbished parts refer to second-hand parts that have been repaired and remanufactured. Usually, these parts undergo a professional refurbishment process to restore their functions and appearance to a state close to that of new parts. Refurbished parts are relatively cheap and environmentally friendly, but their quality and service life often depend on the refurbishment process and standards.

Classification 2: Properties
According to the properties of auto parts, they can be divided into engine system, power system, transmission system, suspension system, brake system, electrical system, others (general supplies, loading tools, etc.), etc.
- Engine system
The engine system is the core power source of the car, and is mainly responsible for converting the chemical energy of the fuel into mechanical energy to drive the car forward. The components of the engine system include cylinders, pistons, crankshafts, fuel injection systems, cooling systems, exhaust systems, etc.
- Power system
The power system transfers the power generated by the engine to the wheels to ensure that the vehicle can move. The system includes the fuel system, intake system, turbocharger, exhaust system, etc.
- Transmission system
The function of the transmission system is to transfer the power of the engine to the wheels and adjust the transmission ratio as needed. The main components of the transmission system include the transmission, clutch, differential, drive shaft, etc.
- Suspension system
The suspension system connects the wheels to the body through springs and shock absorbers to ensure that the vehicle can effectively absorb vibrations during driving and provide a smooth driving experience. The main components include shock absorbers, springs, suspension arms, etc.
- Braking system
The braking system is responsible for slowing down or stopping the vehicle while it is driving to ensure safety. Common braking system components include brake discs, brake drums, brake calipers, brake pads, brake fluid, etc.
- Electrical system
The electrical system provides power to the vehicle and controls various electrical equipment. The system includes electronic equipment such as batteries, generators, lights, dashboards, electric windows, and audio systems.
- Others (general supplies, loading tools, etc.)
In addition to the main mechanical systems, there are also some accessories and tools related to comfort and convenience, such as interior parts, seats, air conditioning systems, navigation systems, roof racks, etc.

Classification 3: Purpose
According to the purpose of auto parts, they can be divided into consumable parts, wearing parts, repair parts, basic parts, accident parts, and modified parts.
- Consumable parts
Consumable parts refer to accessories that gradually wear out or fail with the use of the vehicle and need to be replaced regularly. Such accessories have a clear service life. Common consumable parts include engine oil, filters (air filters, oil filters, fuel filters), brake pads, wipers, spark plugs, etc.
- Wearing parts
Wearing parts refer to accessories that are easily worn, collided or damaged during the use of the vehicle, and are usually replaced more frequently. Common wearing parts include tires, lights, rearview mirrors, bumpers, etc.
- Repair parts
Repair parts refer to parts that need to be replaced or repaired when a vehicle fails. Usually, such accessories are repaired or replaced according to the specific situation after the failure occurs, such as engine parts, transmission components, steering system parts, etc.
- Basic parts
Basic parts refer to the core components used for the basic structure and operation of the vehicle. These parts are usually not easy to damage, but once damaged, they need professional repair. Basic parts include frame, chassis, engine, transmission system, etc.
- Accidents
Accidents refer to parts that need to be replaced due to traffic accidents or other collisions of the vehicle. Such accessories usually include external body parts such as doors, windshields, headlights, bumpers, etc.
- Modified parts
Modified parts are parts used to improve or change the performance, appearance or function of the vehicle. Modified parts are usually not to replace damaged original parts, but to meet the owner's demand for vehicle personalization or high performance. Common modified parts include high-performance suspension systems, sports exhaust systems, custom wheels, body kits, etc.
Vol.4
Maintenance methods
According to the maintenance methods of auto parts, they can be divided into DIY and DIFM.
- DIY (Do It Yourself)
DIY means that the owner repairs and maintains the vehicle by himself. It is suitable for owners with certain hands-on ability and is usually simple to operate. For example, the owner can replace consumable parts such as oil, air filter, wiper, or tires, lights, etc. DIY projects usually do not require complex equipment and can save maintenance costs.
- DIFM (Do It For Me)
DIFM means that the owner hands the vehicle over to professional maintenance personnel or shops for processing. It is suitable for complex maintenance projects. For example, engine repair, replacement of suspension system, transmission repair, or handling of body damage after an accident usually requires professional equipment and technology. Complex modification parts installation, such as high-performance brake systems or suspension systems, also need to be carried out by professionals.
