What is the definition of automobile parts?

Automobile parts are the "organs" that make up a Automobile; missing a crucial part renders the Automobile inoperable, while extra decorative parts only make it more flashy.

I. Essential Parts (Without them, the Automobile won't move)

• Heart Parts

Engine Piston: The "air pump" that moves back and forth in the cylinder; without it, the Automobile is completely dead.
Transmission Gear Set: The "gear blocks" that transmit power; a broken gear turns the transmission into scrap metal.

• Life-Saving Parts

Brake Master Cylinder: The "pressure cooker" when you step on the brakes; a leak is equivalent to suicide.
Seatbelt Retractor: The "locking mechanism" during a collision; failure is equivalent to driving without a seatbelt.

II. Functional Parts (Affecting the driving experience)

• Sensing Parts

Wheel Speed ​​Sensor: The "eyes" of the anti-lock braking system; if dirty, it will give false alarms.
Water Temperature Sensor: Monitors the engine for "overheating"; failure leads to engine overheating.

• Comfort Parts

Air Conditioning Compressor: The "air conditioning pump" that keeps you alive in the summer; unusual noises mean it needs replacing.
Engine Mounts: The "rubber pads" that filter vibrations; aging makes the steering wheel feel like a massager.

III. Consumable Parts (Require regular replacement)

• Liquid Gold

Engine Oil: The "blood" of the engine; must be changed when it turns black.
Brake Fluid: The "pressure fluid" that absorbs water; deteriorates after two years.

• Wear Parts

Brake Pads: The "shoe soles" that get thinner and thinner; worn out pads make a screeching sound.
Wiper Blades: Age and "draw maps" on the windshield; replace them when they don't wipe cleanly.
