Vehicle spare parts are those that people store in their inventories and use when a vehicle part needs replacement. Some spare parts are crucial for the safe and effective functioning of a vehicle.
It is crucial for every car owner to know about such vehicle spare parts and recognise their signs of decline. This article lists down the important spare parts of an automobile, their working and importance.
The engine is the nucleus of your car. It is a complex piece of machinery that lies under your vehicle's hood and powers it. The sole purpose of a car engine is to convert energy and make the wheels run smoothly. The engine helps in the combustion of petrol and air to produce energy that runs the vehicle.
The engine has a robust structure to withstand heavy workloads. It has two basic parts, a cylinder block which is the lower heavier section and a cylinder head, the detachable cover above. The cylinder head has valve-controlled pathways that allow entry of air and fuel composition. It also consists of some outlet valves that expel gases produced during combustion.
The cylinder block has a crankshaft and camshaft. The crankshaft converts reciprocating motion to rotatory motion that lets the car run. In comparison, the camshaft monitors the opening and closing of valves present in the cylinder head.
The engine must function smoothly and not overheat for the quality life of your vehicle. Therefore, every car owner must monitor the engine light on their car dashboard to detect any engine error. One should opt for timely service if the check engine light starts to blink. If an important vehicle spare part in the engine has been damaged, it will be replaced.
Know more about:
A car battery is crucial for an engine to start combustion. A weak or dead battery will not ignite the engine or allow other parts of your car to function. It is also the heart of your car's electric system. Stereo, AC, bulbs, and windows are a few of those electric components that require a healthy and functioning battery.
When you take the driver's seat, you will notice that your car starts instantly as you press a button or twist a key. But, what happens within your car that powers its engine so quickly?
When you turn on the ignition, the battery converts chemical energy to electrical energy. A car battery is the powerhouse of your vehicle. As you turn on the key, car batteries receive a signal to generate maximum voltage for the spark plug. Power is sent to the engine, which ignites the fuel in your car's combustion chamber.
The battery also sends power to other vehicle parts, such as lights, air conditioning, etc. As your car’s engine keeps running, it powers the alternator, which generates electricity and recharges its battery. Some of the factors that determine if a car battery will continue to function are cranking power, battery voltage, and chemical reactions.
It is important to remember that every other car model has specific energy requirements. Therefore, it is mandatory to use the right battery to maintain your car's longevity.
Low lights, weak horns or engine not igniting are some signs of weak car batteries. Therefore, it is necessary for vehicle owners to monitor their batteries regularly and replace them when the battery condition deteriorates.
Brakes are also an essential automobile spare part; therefore, car owners must monitor them regularly. We can find two kinds of brakes in a car. They are drum brakes and disc brakes. Disc brakes are located in the front tyres of your vehicle, while drum brakes are situated in the rear tyres.
The primary function of car brakes is to absorb kinetic energy to slow down and stop your car. These brakes convert kinetic energy to heat with the help of friction. Cars today come with brakes on all four wheels. Brakes on the front wheels make a car stop or slow down. In contrast, rear wheel brakes redirect energy to the front. This makes your vehicle stop due to inertia.
Modern cars use a hydraulic system for the efficient functioning of brakes. The hydraulic brake cylinder contains fluid in its master and slave cylinders. The functioning of brakes begins when a driver pushes the brake pedal.
As you push these brake pedals, they exert pressure on the piston in the master cylinder that releases hydraulic fluid. This fluid travels to slave cylinders located in your car's wheels and forces the piston to apply brakes.
When you hear disturbing noises from brake pads while driving, you must know it is time to replace your automobile’s brake parts. Leaking brake fluid or vibration during braking are other symptoms of brake-related problems. It is always a good idea to get high-quality vehicle spare parts for replacement.
Like engines and batteries, spark plugs are essential vehicle spare parts. As its name suggests, these are devices that produce electric sparks to start the combustion process in a vehicle.
They emit electricity through a small gap, igniting air and fuel. This ignition is strong enough to power your vehicle's piston and get the wheels rolling.
The spark plugs generate electric sparks as soon as you press the ignition button or start your vehicle using the key. This makes spark plugs an important vehicle spare part every car owner must monitor.
Friction which causes wear and tear in spark plugs is one of the main reasons for their deterioration. They can lose their power to ignite or their ability to generate sparks to initiate the combustion process. Overheating, combustion and contamination over the course of time are a few reasons for a spark plug’s decline.
If you do not replace spark plugs, the gap between them widens. Consequently, electric signals have to make longer jumps for a successful ignition. Gradual widening of these gaps leads to erratic and irregular combustion. If your vehicle is taking a long time to start, or producing a knocking, rattling or pinging sound, it may be time to replace its spark plugs.
This is an essential vehicle spare part that allows the passage of fuel from a car's fuel tank to its engine. It helps to monitor how much oil mixes with air for proper combustion.
When a driver presses the gas pedal, a throttle valve opens, allowing entry of air. Meanwhile, the fuel injector sprays fuel as mists which mix with air and enter an engine's combustion chamber.
Fuel injectors follow two fuel injection systems. First, a continuous injection squirts fuel into the inlet port while a car engine is running. Timed or pulsed injection allows fuel flow to happen in bursts that coincide with the injection stroke of cylinders.
You will want to monitor the state of fuel injectors and change them as they get clogged with dust and impurities. If you neglect them, your vehicle's engine will not receive sufficient oil for combustion. This will further lead to poor acceleration, engine performance and mileage. A clogged fuel injector also emits harmful carbon particles and hydrocarbons into the air.
Your car’s suspension system ensures that its tyres stay in proper contact with the road regardless of its condition. A car with good suspension cushions the effects of jerking when it goes over bumps or potholes. This makes suspension parts integral vehicle spare parts for a car to function.
A suspension system works to maximise the friction between roads and tyres. It uses parts like dampers, springs, and struts to achieve proper suspension and provide a comfortable ride. Spring in its coiled structure holds energy generated when your vehicle encounters a bump.
There are two types of springs popularly used in the suspension system. Coil springs can be found in cars or bikes, and leaf springs in vehicles like trucks. These springs cushions riders on uneven and bumpy roads.
The dampers act as shock absorbers that seep in energy which springs store. Without dampers, the stored energy in spring will release and make your vehicle jump at the smallest inconvenience.
Strut is damper wrapped with a coil spring. It also functions similar to how a damper and spring would function individually. This shock-absorbing function makes the suspension system an important vehicular spare part.
Wear and tear and driving on harsh road conditions can damage the components of your vehicle’s suspension. If you notice signs such as continued bouncing and nose-diving on applying brakes, it indicates work shock absorbers. If your vehicle stands lopsided on even ground, some vehicle spare parts may need replacing.
As the contact point between your vehicle and road, tyres are an essential part of your vehicle. It might look like a simple, sturdy rubber disc; however, very elaborate engineering goes into its making.
A tyre's construction and design very much depend upon a type of vehicle, geography, and many other factors. For instance, an off-road or heavy-duty vehicle will have a different tyre set than a passenger car we usually see.
A well-maintained car tyre will provide your vehicle with efficient speed, mileage, and economical fuel consumption. They will also respond well to brakes, thus maintaining good road resistance when you apply brakes or take sharp turns.
You will find different components in a car tyre serving different purposes. However, like most parts, you must change them after a certain period. If left unchanged, car tyres shall wear out due to friction and might skid easily while driving. In addition, poorly maintained tyres consume excess fuel and energy and make your ride uncomfortable.
A clutch helps a car to shift from one gear to another. It transfers rotational power from a car's engine to its wheels.
The engine and gearbox come in contact when you release the clutch pedal. Likewise, the connection gets broken when you press the clutch pedal. This is necessary when you wish to halt your car without turning off the engine. At this point, the wheel will continue spinning for some distance. This is due to its momentum and not the vehicle's power.
Normal wear and tear over the years or rough driving conditions can create problems with your vehicle’s clutch system. The master cylinder may start to leak, the clutch disc could be worn out, or the flywheel may become warped. If these problems occur, you may need to replace these vehicle spare parts.
The cabin air filter or AC filter plays a crucial role for riders to enjoy a fresh and healthy ride. These AC filters help eliminate harmful air pollutants, dust and pollens that can be hazardous to your lungs.
You can find these cabin filters behind your vehicle's glovebox. They consist of small blinds made of paper or micro-fibre cotton, which detoxifies the air that enters via HVAC ducts. These blinds trap dust particles and other impurities while providing fresh air to your vehicle.
These filters require changing when they have accumulated too much dust. If you neglect them, air volume in passengers' compartments will fall, and a foul odour will remain. In addition, people prone to allergies must consider changing air filters frequently.
Every car owner should change his/her cabin filters after around 19,312 km for a pleasant and healthy ride. We must also keep in mind that the location determines the frequency of replacing AC filters. For instance, if you regularly travel through a chaotic city with a low air quality index, your cabin filters require frequent replacements.
Weak airflow, even at high speed, unpleasant odours, and whistling sounds from air cabin ducts are a few signs of a poorly functioning air filter. If you notice these symptoms, it may be time to replace the filters.
To enjoy a safe ride and ensure vehicle longevity, monitoring the above-mentioned vehicle spare parts is necessary. Ignoring the signs for an immediate car repair would likely result in more losses. Therefore, cars need regular check-ups and maintenance to avoid sudden breakdowns or excessive fuel consumption.
