An automobile consists of 7 major component groups. Below is a detailed introduction to vehicle parts: Engine Components: Total 29 parts, including main components such as pistons, piston rings, cylinder head gaskets, shims, valves, fuel pumps, electronic fuel injection pumps, etc. Electrical and Electronic Equipment: Total 12 components, primarily including starters, alternators, spark plugs, engine control units, brake system electronics, electronic components and sensors. Lighting and Electrical Devices: Total 15 components, mainly consisting of headlights, speedometers, wiper motors and other electric motors, various switches, steering locks, wiring harnesses. Powertrain and Control Systems: Total 26 components, with major parts including clutch driven plates, manual transmissions, automatic transmissions, power steering systems, constant velocity joints, drive shafts, wheels, gear shift levers. Suspension and Braking Components: Total 20 parts. Principal components comprise leaf springs, shock absorbers, and braking systems. Body Components: Total 19 parts, mainly including frames, fuel tanks, window frames, door handles and locks, seats with springs, seat belts. Accessories: Total 9 items, featuring clocks, radios, air conditioning units, heating systems, wheel covers, touch-up paint, car stereo systems.

Since childhood, I've loved tinkering with car parts, feeling like the whole vehicle is one big puzzle. The engine section has core components like the cylinder block, pistons, and crankshaft, along with the intake manifold and exhaust system that help air flow. The transmission controls speed, with gears clunking during shifts. As for the chassis, the suspension system ensures a smooth ride, brake pads slow things down when pressed, and tires with rims are the first line of contact with the ground. The body part includes doors, windows, roof, and frame as protective shells for passengers. The electrical system is more complex—the battery powers up, the dashboard displays speed, while headlights and horns assist nighttime driving. Oh, and the AC compressor keeps the interior cool, with belts transmitting power to auxiliary systems. All tallied up, there are hundreds of parts big and small. When repairing cars, I often find engine issues most common—replacing a single part can save a lot of money.

After driving for so many years, I've gotten used to dividing a car into three main parts: the small components under the hood, like the engine block, coolant tank, and alternator, which buzz as soon as the power source starts; the seats, steering wheel, and seat belts inside the car are what I interact with daily and need to be handy to control; the external structures such as the headlights for illumination, door handles for entry and exit, and the wheel components—tires wear out too fast and need regular inspection and replacement. The suspension and steering system under the chassis ensure smooth turns, while brake pads wear easily, so I check them every quarter. The electrical system includes the horn button, navigation screen, and Bluetooth that plays music as soon as it connects. Overall maintenance is straightforward—first check the engine oil and coolant level to avoid breaking down on the road.

Looking back to the early days of driving, car parts were basically divided into functional blocks: the powertrain, such as the engine block and fuel pump, drove the entire vehicle; the passenger area had seat frames and seat belt buckles, making it more comfortable to sit in; the wheel section included suspension springs and brake discs, where shock absorption was crucial. Electrical components like the battery box and headlight wiring ensured clear visibility at night. Other auxiliary parts, such as the radiator circulating coolant and the air conditioning system, regulated the temperature. Maintaining an old car required attention to issues like engine overheating or aging wires, and simple repairs could extend its lifespan.
