Parts of a Car

Let’s Discuss one by one part of a car:

Engineering Choice The Biggest Learning Platform

1. Steering wheel

You use the steering wheel to control the direction of the car (steer the car).

A steering wheel and the system it connects to primarily control the direction of a vehicle. It converts the rotational commands of the driver into swiveling movements of the vehicle’s front wheels.

The driver’s movement passes through a series of joints and hydraulic lines in the steering system, ultimately reaching the rubber as it hits the road.

Modern steering wheels also often have accessory functions built-in, such as cruise control, audio system selection, and volume. Some steering wheels are even electrically heated.

2. Speedometer

A speedometer, an instrument that indicates the speed of a vehicle, is usually combined with a device known as an odometer that records the distance traveled.

A speedometer or a speed meter is a gauge that measures and displays the instantaneous speed of a vehicle. Now universally fitted to motor vehicles, they started to be available as options in the early 20th century, and as standard equipment from about 1910 onwards.

Speedometers for other vehicles have specific names and use other means of sensing speed. For a boat, this is a pit log. For an aircraft, this is an airspeed indicator.

3. Seat Belt

A seat belt (also known as a safety belt, or spelled seatbelt) is a vehicle safety device designed to secure the driver or a passenger of a vehicle against harmful movement that may result during a collision or a sudden stop.

A seat belt reduces the likelihood of death or serious injury in a traffic collision by reducing the force of secondary impacts with interior strike hazards, by keeping occupants positioned correctly for maximum effectiveness of the airbag (if equipped), and by preventing occupants from being ejected from the vehicle in a crash or if the vehicle rolls over.

When in motion, the driver and passengers are traveling at the same speed as the car. If the driver makes the car suddenly stop or crashes it, the driver and passengers continue at the same speed the car was going before it stopped.

A seatbelt applies an opposing force to the driver and passengers to prevent them from falling out or making contact with the interior of the car (especially preventing contact with, or going through, the windshield).

Seatbelts are considered Primary Restraint Systems (PRS), because of their vital role in occupant safety.

4. Gear Shift

The gearshift is used to move a vehicle forward, in reverse, or remain neutral. On cars with a manual transmission, the gearshift is actually a stick shift.

A gear stick, gearshift, or shifter, more formally known as a transmission lever, is a metal lever attached to the transmission of an automobile.

The term gear stick mostly refers to the shift lever of a manual transmission, while in an automatic transmission, a similar lever is known as a gear selector.

A gear stick will normally be used to change gear whilst depressing the clutch pedal with the left foot to disengage the engine from the drivetrain and wheels.

Automatic transmission vehicles, including hydraulic (torque converter) automatic transmissions, automated manual and older semi-automatic transmissions (specifically clutchless manuals), like VW Autos, tick, and those with continuously variable transmissions, do not require a physical clutch pedal.

5. Windshield/Windscreen

The windshield or windscreen is the front window, which provides visibility while protecting occupants from the elements.

Modern windshields are generally made of laminated safety glass, a type of treated glass, which consists of, typically, two curved sheets of glass with a plastic layer laminated between them for safety, and bonded into the window frame.

Motorbike windshields are often made of high-impact polycarbonate or acrylic plastic.

Windshields protect the vehicle’s occupants from wind and flying debris such as dust, insects, and rocks, and provide an aerodynamically formed window towards the front. UV coating may be applied to screen out harmful ultraviolet radiation.

However, this is usually unnecessary since most auto windshields are made from laminated safety glass. The majority of UV-B is absorbed by the glass itself, and any remaining UV-B together with most of the UV-A is absorbed by the PVB bonding layer.

6. Windshield Wipers

A windscreen wiper or windshield wiper is a device used to remove rain, snow, ice, washer fluid, water, and/or debris from a vehicle’s front window so the vehicle’s operator can better see what’s ahead of them.

Almost all motor vehicles, including cars, trucks, buses, train locomotives, and watercraft with a cabin and some aircraft are equipped with one or more such wipers, which are usually a legal requirement.

A wiper generally consists of a metal arm; one end pivots, the other end has a long rubber blade attached to it. The arm is powered by a motor, often an electric motor, although pneumatic power is also used for some vehicles.

The blade is swung back and forth over the glass, pushing water, other precipitation, or any other impediments to visibility, from its surface. On vehicles made after 1969, the speed is normally adjustable, with several continuous speeds, and often one or more intermittent settings.

7. Headlights

A headlamp is a lamp attached to the front of a vehicle to illuminate the road ahead. Headlamps are also often called headlights, but in the most precise usage, headlamp is the term for the device itself and headlight is the term for the beam of light produced and distributed by the device.

Headlamp performance has steadily improved throughout the automobile age, spurred by the great disparity between daytime and nighttime traffic fatalities: the US National Highway Traffic Safety Administration states that nearly half of all traffic-related fatalities occur in the dark, despite only 25% of traffic traveling during darkness.

8. Tail Lights/Turn Signal

Tail Lights are mounted to the rear of the car above the bumper. They are red in color and have accompanying white lights beside them to indicate when the vehicle is in reverse.

When you’re on the road, tail lights make another car aware of your presence so that you can travel safely in the dark.

Direction-indicator lamps or turn signals, informally known as “directional signals”, “directional”, “blinkers”, or “indicators”, are blinking lamps mounted near the left and right front and rear corners of a vehicle, and sometimes on the sides or on the side mirrors of a vehicle, activated by the driver on one side.

9. Car Hood

A car hood also referred to as a bonnet in some other countries is the hinged cover that rests over the engine of a front-engine vehicle. Its purpose is to provide access to the engine for repair and maintenance.

A concealed latch is typically used to hold down the hood. On vehicles with an aftermarket hood and on racecars, hood pins may be used to hold down the car hood.

Hoods sometimes also contain a hood scoop, wiper jets, power bulge, and/or hood ornament. Car hoods are typically constructed from steel and sometimes from aluminum.

10. Trunk

Typically, a car trunk is the primary storage area for cargo or luggage in a sedan, coupe, or convertible. The word “trunk” is used primarily in North America, while the word “boot” is often used in other English-speaking countries.

Prior to the introduction of automobiles, the boot was a compartment that was built into a horse-drawn carriage. It was usually used as a seating area for the coachman. Later, it was used for storage purposes.

The car trunk is typically located in the rear of the car in most models. In some vehicles in which the engine is located in the middle or the rear of the vehicle, the trunk is located at the front. In some models, there have been two trunk compartments.

11. Wheel/Tire

Every car has four wheels. The black part of the wheel, which is made out of rubber with air inside, is called a tire.

They’re where your tires are actually attached. The inner part of your car tire is attached to the rim. You’ll often hear people use “rims,” and “wheels,” interchangeably, where decorative wheels are called rims. Some people may also say “tire,” when they actually mean wheel.

12. Engine

The engine is the heart of your car. It is a complex machine built to convert heat from burning gas into the force that turns the road wheels.

It consists of two basic parts: the lower, heavier section is the cylinder block, a casing for the engine’s main moving parts; the detachable upper cover is the cylinder head.

The engine block features parts such as the timing chain, camshaft, crankshaft, spark plugs, cylinder heads, valves, and pistons.

13. Transmission

A car transmission is a vehicle’s gearbox. It’s roughly analogous to the gear shifter and chain system that bicycles use.

These components are always mounted straight on the engine so that their attached belt and gear system can effectively convert the combustion power produced by the engine into physical momentum.

A transmission changes gears depending on car speed and accelerator input (i.e., how far down you push the pedal of your car) so that the engine’s RPM or “revolutions per minute” are kept appropriately low.

This provides two benefits: Fuel consumption is decreased, and The turning gears do not overload your engine.

14. Battery

Your car battery provides the zap of electricity needed to put electrical components to work. Talk about a pretty huge responsibility. Without battery power, your car, as you’ve probably noticed, won’t start.

Let’s take a look at how that powerful little box works:

  • A chemical reaction puts your car in action: Your battery converts chemical energy into the electrical energy necessary to power your car, delivering voltage to the starter.
  • Keep the electric current steady: Not only does your battery provide the energy required to start your car, it’s also stabilizing the voltage (that’s the term for the energy supply) in order to keep your engine running. A lot’s riding on the battery. Call it the ‘little box that could.’

15. Alternator

While the battery is essential for starting your car when it’s off, the alternator keeps your car alive when the engine is running.

The alternator powers most car’s electronic components while you’re driving around or idling, including your headlights, electric steering, power windows, windshield wipers, heated seats, dashboard instruments, and radio.

The alternator supplies all of them with direct current (DC) power. Your alternator is also responsible for charging your car battery while driving.

The alternator works by turning mechanical energy into electrical energy. When your engine is on, it powers a drive belt that rests on a pulley attached to the alternator. The pulley turns the alternator’s rotor shaft, which spins a set of magnets around a coil.

These spinning magnets generate alternating current (AC) around the coil, which is then channeled to the alternator’s rectifier. The rectifier converts that AC power into DC power, which activates your car’s electrical systems.

16. Radiator

A radiator helps to eliminate excess heat from the engine. It is part of the engine’s cooling system, which also includes a liquid coolant, hoses to circulate the coolant, a fan, and a thermostat that monitors the coolant temperature.

The coolant travels through the hoses from the radiator, through the engine to absorb the excess engine heat, and back to the radiator.

Once it returns to the radiator, thin metal fins release the heat from the coolant to the outside air as the hot liquid passes through it.

Cool air flows into the radiator through the car’s grille to aid in this process, and when the vehicle isn’t moving, such as when you’re idling in traffic, the system’s fan will blow air to help reduce the heated coolant’s temperature and blow the hot air out of the car.

17. Front Axle

Part of the suspension system, Located in the front of the vehicle, this axle is responsible for assisting with steering and processing shocks from the uneven surface of the road. They have four main parts, which are the beam, the swivel pin, the track rod, and the stub axle.

18. Shock Absorber

Shock absorbers are hydraulic (oil) pump-like devices that help to control the impact and rebound movement of your vehicle’s springs and suspension.

Along with smoothening out bumps and vibrations, the key role of the shock absorber is to ensure that the vehicle’s tires remain in contact with the road surface at all times, which ensures the safest control and braking response from your car.

Shock absorbers do two things. Apart from controlling the movement of springs and suspension, shock absorbers also keep your tires in contact with the ground at all times.

At rest or in motion, the bottom surface of your tires is the only part of your vehicle in contact with the road. Any time that a tire’s contact with the ground is broken or reduced, your ability to drive, steer, and the brake is severely compromised.

19. Brakes

A brake is a mechanical device that inhibits motion by absorbing energy from a moving system. It is used for slowing or stopping a moving vehicle, wheel, axle, or to prevent its motion, most often accomplished by means of friction.

Without working brakes, your car simply won’t be able to stop in time. This can cause anything from a small fender bender to a major accident, neither of which is worth the risk. Regular brake maintenance helps ensure that your brakes engage every time you press on the brake pedal.

20. Catalytic Converter

A catalytic converter is an exhaust emission control device that converts toxic gases and pollutants in exhaust gas from an internal combustion engine into less-toxic pollutants by catalyzing a redox reaction.

Catalytic converters are usually used with internal combustion engines fueled by petrol or diesel, including lean-burn engines, and sometimes on kerosene heaters and stoves.

21. Muffler

Mufflers are part of your vehicle’s exhaust system and are located at the rear, the bottom of your vehicle. They aid in dampening vehicle emissions and engine noise.

They are made of steel and are coated with aluminum to provide protection from the heat and chemicals released from the exhaust system. Mufflers are used mainly to dissipate the loud sounds created by the engine’s pistons and valves.

22. Tailpipe

The Tail Pipe is part of your car’s exhaust system. Like a chimney on a house, it is designed to release exhaust away from the vehicle and into the air. Exhaust pipes connect to the muffler and are often attached to the rear end of the car with a bracket.

Exhaust pipes are susceptible to damage from rear-end collisions, failed brackets, broken seals, and corrosion from age.

23. Fuel Tank

The fuel tank on your car is typically located under the rear or middle of the vehicle. There can be a number of reasons why you would need to remove it; the most common reason is needing to replace the fuel pump.

This tank can be filled from the outside via a small hole that is sealed with a gas cap when not in use. The gas then goes through a few steps before it reaches the engine. The pump pushes gasoline into the fuel lines.

There are hard metal fuel lines in most vehicles that run the fuel from the tank towards the engine.

24. Rear Axle

The rear axle is located between the differential and the driving wheels and transmits power between the two. The rear axle is actually two halves – connected by the differential – with each part known as the half shaft.

This axle is responsible for delivering power to the driving wheels. It comes in two halves, which are connected by the differential. In most vehicles, the rear axles rotate with the vehicle’s wheels.

25. Suspension

Suspension is the system of tires, tire air, springs, shock absorbers, and linkages that connects a vehicle to its wheels and allow relative motion between the two.

Suspension systems must support both road holding/handling and ride quality, which is at odds with each other.

The tuning of suspensions involves finding the right compromise. It is important for the suspension to keep the road wheel in contact with the road surface as much as possible because all the road or ground forces acting on the vehicle do so through the contact patches of the tires.

The suspension also protects the vehicle itself and any cargo or luggage from damage and wear. The design of the front and rear suspension of a car may be different.

26. Fuel gauge

A fuel gauge is a device that measures the fuel level present in the vehicle. It consists of a sensing or a sending unit that helps to measure the amount of fuel.

A gauge or indicator which is placed outside the fuel tank uses the information from the sensing unit to give the measure of fuel.

The lines on the gas gauge are increments of 1/4 representing your gas tank’s fuel level. Anything between 2 lines would be an eight. If the needle were between 1/2 and 3/4, this would mean you have 5/8 of gasoline in your tank.

27. Temperature gauge

The temperature gauge in your vehicle is designed to measure the temperature of your engine’s coolant. This gauge will tell you if your engine’s coolant is cold, normal, or overheating. It is an important dial that is located on the dashboard of your vehicle.

When the engine is functioning, and the coolant is doing its job, the temperature gauge needle should be somewhere in the middle between the hot and cold indicators.

“Normal” temperature reading can vary from vehicle to vehicle so don’t be alarmed where yours settles.

28. Car trip meter

A Trip meter is an instrument used for measuring the distance traveled by a vehicle, such as a bicycle or a car.

That is most likely the trip-odometer showing the miles traveled for trip A. Push the button there near the speedometer and it should show mileage traveled for trip B. Push it again and it should show the current ‘overall mileage’ on the vehicle.

To read an odometer, look for the small rectangle usually containing five or six numbers. It is typically located near the speedometer. If your vehicle is newer, it may be digital. If your vehicle is older or less luxurious, it will be a physical, mechanical set of numbers.

29. Rev counter

A tachometer (revolution-counter, tach, rev-counter, RPM gauge) is an instrument measuring the rotation speed of a shaft or disk, as in a motor or other machine. The device usually displays the revolutions per minute (RPM) on a calibrated analog dial, but digital displays are increasingly common.

A rev counter simply shows the number of revolutions an engine’s crankshaft (that’s the rotating bit which converts the reciprocating motion [in a car’s case, the up and down motion of the con-rods and pistons] to circular motion) is revolving per minute (RPM) – usually divided by 1000.

30. License Plate/Bumper Stickers

The license plate in the picture is a blue and white sign. Every car must have a license plate for identification. This car also has many bumper stickers. These are decorations you can put on your car.

This is a list of automotive parts, mostly for vehicles using internal combustion engines which are manufactured components of automobiles.
