50+ List of Car Spare Parts and Their Functions

The car is a general transportation that is now owned by many people. As car owners, of course, we must understand the various kinds of car spare parts and their functions.

There are many spare parts in the car. Starting from spare parts on the car engine to spare parts for the outside of the car such as brake linings, lights, wipers and others. There are spare parts that must be replaced regularly so that the car is ready to be taken anytime and anywhere.

The following is a list of car spare parts and their functions:

Name of Spare PartFunction
Cylinder HeadAs a combustion chamber, a place for spark plugs, and a mechanism for the intake valve and exhaust valve.
Suction ValveOpens and closes the suction hole needed when combustion occurs in the combustion chamber.
Exhaust ValveOpens the exhaust hole when the combustion process is complete and closes when the suction, compression and work processes take place.
CamshaftSets the opening and closing of the intake valve and exhaust valve.
Rocker ArmWhere the camshaft presses the intake and exhaust valves.
Cylinder Head CoverCover the cylinder head.
Spark PlugsProduce sparks when the combustion process happen in the combustion chamber.
Intake ManifoldAir intake into the combustion chamber.
Exhaust ManifoldExhaust duct for combustion residues.
Cylinder BlockHolder for all engine components.
GasketPrevents engine oil leakage between engine block and cylinder head.
PistonAdjusts the volume in the cylinder.
Piston RingPrevents leakage between the piston and the cylinder wall.
Connecting RodConnects the piston to the crankshaft.
CrankshaftConverts rotary motion to up and down.
Oil PanA place to accommodate lubricating oil for lubricating components in the engine.
Drain PlugThe bolt opens or closes the engine oil passage when engine oil is being drained.
PulleyAdditional component connected to the belt.
FlywheelTransmission of power from the combustion engine to the clutch
Timing ChainConnecting the crankshaft to the camshaft.
Timing Chain CoverCover the timing chain.
Motor StarterStarts the car engine using electrical energy from the battery.
Drive BeltBelt that connects one component to another.
RadiatorCools the engine by channeling the coolant to the cylinder block through the water jacket.
ThermostatMonitors and maintains the coolant temperature of the radiator.
Cooling FanCools the engine and radiator fins by generating wind from the rotating fan.
Reservoir TankA place to store radiator water reserves.
Water Temperature SensorMonitors the temperature of the radiator coolant which will affect the cooling fan.
AlternatorGenerates electrical energy by utilizing the rotary motion of the engine which will be channeled to charge the battery.
RegulatorRegulates the output voltage generated by the alternator so that it does not overvoltage.
BatteryStores electrical energy generated by the alternator
Oil PumpPumps lubricating oil to all parts of the engine that require lubrication.
Oil FilterFilters oil from dirt and water so that the oil in the engine is clean.
Fuel TankHolds the fuel that will be used for the combustion process.
Fuel FilterFilters fuel before it is channeled to the outside of the fuel to keep it clean of water and dirt.
Fuel LineAs the fuel line to the combustion chamber.
Fuel PumpPumps fuel from the fuel tank into the combustion chamber
CarburetorMixes air and fuel before entering the combustion chamber.
InjectorSprays fuel to enter the combustion chamber according to the needs of the engine.
Intake Air Temperature SensorSets the temperature of the air that will enter the Intake Manifold.
Mass Air Flow Pressure SensorCalculates the mass of air that will enter the Intake Manifold.
Throttle Position SensorAdjusts the gas valve opening angle as needed.
Manifold Air Pressure SensorMeasures and maintains the air pressure inside the Intake Manifold.
Crankshaft Position SensorMeasures engine speed (rpm).
Camshaft Position SensorKnowing the position of the piston during the compression stroke so that the timing for ignition can be adjusted.
Air Fuel Ratio SensorDetects the air and fuel mixture in the fuel tank.
Oil Pressure SensorKnowing the oil pressure in the engine.
Oxygen SensorKnowing the emission levels released by the engine.
Engine MountingDampens vibrations caused by the engine.
Ball JointConnects the steering knuckle to the inner arm.
Tie RodDampens vibration up and down the wheel.
Brake PadsComponents to reduce the speed of the car by rubbing the brake disc
Rack SteerConnecting between the steering wheel with the bottom of the car.
Bushing ArmThe fulcrum of the wheel with other components.
Shock AbsorberAbsorbs the shock caused by uneven roads.
LightsIlluminate the road at night.
WiperSweeps water on the windshield of the car which can disturb the driver when it rains.
ECUThe main circuit controls all components through data inputted into the ECU.
AC FilterFilters dust and dirt that will enter the car cabin.

Each type of car may have different spare parts. So as a car owner, you should understand about car spare parts, so that when a breakdown occurs, you can find out the cause.
