In China, a strict lifelong accountability system for frame number and engine block number is implemented. In other words, these two parts cannot be replaced and repaired for life, so all other units constituting the whole car are auto parts.
It is preliminarily estimated that a car consists of more than 20000 parts. In addition, the parts of various models of cars may not be universal, so there are many kinds. With the rapid growth of domestic car ownership, this market is also growing.
Auto parts can be roughly distinguished according to the following classification standards:
Power:
Shell mechanism: cylinder head, engine oil pan, etc
Working mechanism: piston body, piston ring, crankshaft, connecting rod, etc
Valve train: exhaust valve, intake valve, tappet, camshaft, etc
Intake: intake filter element, intake manifold, throttle valve, etc
Emission: exhaust manifold, exhaust pipe, three-way catalyst, etc
Transmission: transmission assembly, variable speed control lever, transmission shaft (universal joint), etc
Brake: brake booster, brake disc assembly, brake oil pipe, etc
Steering: steering wheel, steering column, steering knuckle, steering gear, steering rod, etc
Suspension and running: wheel hub, tire, swing arm, tie rod, spring, shock absorber, etc
Ignition: ignition coil, ignition switch, high voltage wire, spark plug, etc
Fuel: fuel tank, fuel filter, fuel pump, fuel pipe, fuel nozzle, etc
Cooling: radiator (water tank), cooling fan, water pump, pipeline, etc
Lubrication: oil filter, oil pump, etc
Instruments: tachometer, speedometer, oil gauge, water temperature gauge, odometer, etc
Lighting: headlamp, headlamp, fog lamp, display lamp, turn signal lamp, reversing lamp, etc
Switch: power switch, steering switch, glass lifting switch, lighting switch, temperature control switch, etc
Air conditioning: air conditioning filter element, compressor, condenser, blower, air conditioning fan, etc
Body: front and rear bumper, windshield, door, fender, seat, center console, box cover, door lock, armrest, floor, threshold, etc.
In addition, there are various sensors that need to be used during the operation of the engine and other systems, such as water temperature, temperature, air bag and safety belt
There are many kinds of auto parts with strong specificity. Replacement and maintenance require considerable skills, as well as necessary equipment and tools. Therefore, combined with the regular maintenance of the car, if you must choose and buy auto parts by yourself, you can look at the packaging, color, appearance, oil paint, texture, process, storage, joint, identification, leakage The key is to look at the test report issued by the third party, which can not only prove the authenticity, but also show its quality.
