A car has many components that can regulate its performance. These components work together to move the car optimally.

The most important components in the car

A car has many components that can regulate its performance. These components work together to move the car optimally. Here are the car parts you need to know.

The most important components in a car

1. Battery

The battery is the car's power center when the engine is not active. The car engine cannot start without electric power. The battery, therefore, acts as a power source in the car.

2. Radiator

The radiator is a liquid cooling system that acts to absorb heat from the engine. The car can thus function optimally and the car's heat remains stable due to the radiator.

3. Tyres

Tires are car components that are directly connected to the road. Good quality tires have a strong grip, so the driver also has better control of the car.

4. Brakes

Brakes work to reduce excessive speed. To keep the brakes in good condition, replace the brake pads regularly.

5. Transmission

The transmission is a power transfer system that transmits the rotation of the engine to the propeller shaft. To maintain the transmission system, change the transmission oil regularly.

6. Suspension

The suspension serves to maintain the comfort of the vehicle. A good suspension system can minimize shocks on rough roads.

7. Alternator

A generator is a dynamo that generates electricity when the car's engine is running. The alternator works to charge the battery. However, you should be aware of the dashboard displays a picture of the battery. This indicates that there is a problem with the car's electricity and it may be caused by the alternator.

8. Powertrain Control Module (PCM)

The PCM acts as the car's information center. It receives data from all the car's sensors, including fuel flow.  Modern cars usually already have this component. 

9. Steering column

The steering column is an important device for connecting the driver to the vehicle. The steering column is the activation center for the car's devices such as lights, wipers, and gear shifters (left-hand steering wheel only).

10. Fuel injection

Fuel injection works by pumping fuel under high pressure from the fuel tank to the injector.

Parts of the car

1. Starting the engine

The ignition key (starting the engine) is located on the dashboard at the bottom right of the steering wheel. Simply insert the car key to start the car. You can also press the button on the dashboard. It depends on the type of car, whether it is new or old.

2. Indicator lights

The car's indicator lights are one of the components on the dashboard. The indicator light is located directly in front of the driver. The indicator lamp is responsible for displaying the engine temperature, doors, airbag indicator, brakes, engine check, rev counter, speedometer, seat belt, and odometer.

3. Steering wheel

The steering wheel is one of the interior elements of the car. Drivers should regularly check the steering wheel for tire movement. Also, check that the power steering is working properly. 

4. Dashboard drawer

The dashboard drawer can be a sign that the car is well-maintained. This is because the dashboard drawer often comes into contact with the driver. A well-functioning drawer and a console with minimal damage will make its function more optimal.

5. Transmission lever

The gear lever is used to move the car or increase speed. To maintain the transmission system, change the transmission oil regularly.

6. Head unit

The head unit on the car's dashboard is used to switch on the entertainment functions in the cabin. There are two types of head units on the market, 1 DIN and 2 DIN.

7. Steering wheel lever

The steering wheel lever makes it easier for the driver to activate some of the car's functions quickly. For example, switching on the headlights at night, signaling to vehicles coming from the opposite direction, switching on the right and left indicators, and turning on the windscreen wipers.

8. Air conditioning (AC)

Air conditioning is an interior component that helps make travel more comfortable. Therefore, you should check the air conditioner regularly. Do not allow the air conditioner to turn off suddenly or the engine to creak when the car is started. This indicates that there is damage to the components that make up the AC.

9. Seat and carpet

Seats and car seats are usually upholstered in leather or plastic. Make sure that the seats and carpets are in good condition.  

10. Control center for car functions

The car control center consists of the air conditioning and lighting settings. This part of the car's interior needs to be maintained regularly to keep it performing.

Safety features in cars

Today, many cars are equipped with advanced safety features to minimize accidents. In addition to seat belts, the following safety features are available in cars.

1. Blind spot detector

The blind spot detector helps the driver to monitor the blind spot from inside the car. In addition to maximizing the field of view in the rearview mirror, drivers can also add other devices, such as blind spot mirrors or blind spot detection systems.

2. Airbags

Airbags can protect the driver and passengers in the cabin in the event of an accident. Airbags protect vital parts such as the head, neck, and chest. The airbag function is activated automatically when there is a collision in certain corners of the car. During a collision, the airbag, which contains nitrogen gas, inflates quickly.

3. Daytime running lights (DRL)

Daytime Running Lights are a safety feature in the form of white LED lights. The DRL has switched on automatically when the car's engine is started. The DRL not only acts as a light but also as a marker to help the car be recognized or seen by other road users.

4. Autonomous Emergency Braking (AEB)

AEB can detect road conditions while driving. It works by automatically applying the brakes when the driver fails to avoid hazards around the car.

5. Child lock

Child lock is a safety feature for children in the car that locks the car door. The door cannot be opened from the inside.

6. Rare rear-view mirror

Rear-view mirrors provide a wide view of the rear of the car, which cannot be seen through the side or center mirrors. This feature is very useful when you need to see the road at night.

7. Electronic Stability Control

This function helps the driver when the car loses control. Its sensors automatically apply the brakes when necessary and then steer the car back on course.

8. Anti-lock Braking System (ABS)

ABS is a feature that controls a car's braking system when the wheels lock during sudden braking. ABS can help steer the car and prevent the tires from locking. It can certainly minimize the occurrence of skidding.

9. Car Glass

The car windscreen or car glass is an important component that prevents dust, wind, and insects from entering the car cabin. On the other hand, the car glass also provides aerodynamic performance from the front while offering a good view for the driver.


What are the engine components?

A car engine has many components, such as the cylinder head, cylinder block, crankcase, piston, piston ring, and crankshaft.

What is the function of the cylinder block?

The cylinder block acts as a place for the piston to rise and fall. The shape of the cylinder bore will match the shape of the piston. The piston will then move up and down in the cylinder bore. Make sure the cylinder bore is smooth and level so the piston can work properly.

Explain what is the function of oil supply?

The oil feed is the oil path that is formed when the engine block is made
