1. Unit 1. Car components

2. I. Engine It makes sense to start with the most important part under the hood of a vehicle, which is the engine. Most modern vehicles run on internal combustion engines, which generate energy by igniting a mixture of air and fuel that moves pistons, which in turn move the car. There are also electric motors, which store energy in rechargeable batteries. Vehicles with electric engines accelerate faster than those with fuel-powered engines. Whether your car has a traditional or electric engine, it can’t run without it!

3. II.Battery Your car’s battery has several important jobs, including providing your vehicle with power to start when you turn on the ignition . Batteries also ensure that other electrical components in your car work properly.

5. Alternator The alternator is responsible for generating electricity. It keeps your battery charged by converting mechanical energy into electrical energy while the car is operating. By continuously charging the battery and keeping the battery charged throughout every trip, it keeps the car and all of the electrical components working correctly.

6. Brakes The brakes on your car are used to help slow down and stop your vehicle, as well as keep it in place when parked. Most cars feature either a disc or drum brake system.

7. Radiator Your car’s engine creates a lot of heat when it’s running, so it makes sense that there would be a cooling system to help manage it. The radiator is one of the major components of this system. It works to remove heat via liquid  coolant  before it circulates back to your engine. The radiator ensures your engine doesn’t overheat, increasing performance and longevity. You can help maintain your radiator by checking coolant levels at least twice a year.

8. Transmission The transmission, otherwise known as the car’s gearbox, is what takes the engine’s power and transfers it to the wheels through various components. Without it, you would simply go nowhere! The transmission transfers the engine’s power to the wheels.

Without it, you would simply go nowhere!

9. Shock Absorbers The suspension system in your car helps stabilize it while you drive. This way, you get a smooth ride and you’re not bouncing around every time you hit a bump or dip. There are many parts that make up the suspension, and shock absorbers play an important role in this system.

10. 1. Engine The engine is the heart of an automobile. It is the powerplant of a vehicle. It is also known as an Internal Combustion engine or IC engine,  It powers the car by burning the air-fuel mixture and converting it into mechanical energy. An engine comprises several other components such as pistons, camshaft, crankshaft, etc.

11. 2. Transmission The transmission, also known as a gearbox, is a critical component of an automobile.  It is a component that transfers the energy produced by the engine to the wheels. It comprises a series of gears of different ratios. The driver can select the smaller or larger gear as per driving conditions. Further, there are two types of transmissions manual and automatic. Manual transmission allows for the driver to shift gears manually. Alternatively, automatic transmissions perform the gear shifts automatically. There are different automatic gearboxes such as CVT, DCT, etc.

12. 3. Clutch In simple words, a clutch acts as a bridge between the engine and transmission. It helps to engage and disengage the transmission of power to the gearbox. In other words, the clutch helps to stop the wheels from spinning without shutting down the engine. The clutch system comprises a clutch pedal, clutch plates, flywheel, etc. In a manual gearbox, the drive has to engage the clutch manually. In an automatic transmission, the system operates the clutch. 

13. 4. Battery Car battery  is a component that powers the car in the first place. Without it, the car won't start. It converts chemical energy into electrical energy to provide the necessary electrical power to the engine and other electrical components. A battery is vital to fire up the engine as it also powers the car's starter motor. Typically, you can find the battery in the engine bay, under the bonnet. You can easily identify the battery with positive (+) and negative (-) symbols on the terminals. 5. Alternator The alternator is part of the car's electrical system. It charges the battery and also powers the electrical system of the vehicle.  An alternator generates electricity by utilizing the mechanical energy created by the car's movement. It converts mechanical energy into electrical energy through an alternating current. Some of the battery issues can be due to the alternator.

14. 6. Radiator The role of the radiator is to prevent from  engine overheating . It flows coolant throughout the engine, absorbs heat and transfers the radiator unit. Generally, you can find the radiator at the front of the vehicle. Hence, the atmospheric air cools down the coolant when the car's on the move. The radiator also has a fan that blows additional air to cool down the coolant if the atmospheric temperature is too high. For a radiator to work correctly, it needs to have a sufficient coolant in the system. 7. Axle Axles are an essential component of an automobile as they help in the vehicle's movement. Axles are attached to the wheels and part of the steering and suspension system. They transfer power from the engine via transmission and differential. Apart from supporting the car's weight, axles also aid in steering, turning and braking.

15. 8. Steering and suspension The steering allows the driver to steer the vehicle precisely. On the other hand, the suspension bears the car’s weight, absorbs shock, and offers a smooth ride. The steering and  suspension systems  work in conjunction to provide stability to a vehicle. The modern  power steering system  reduces driver effort when steering the car. Different suspensions used in automobiles are MacPherson Struts, leaf springs, double wishbone, etc. 9. Brakes Brakes are one of the most crucial pieces of a car's safety equipment. All four wheels come equipped with brakes as it allows to stop or slow down the vehicle or prevent it from moving when it's parked/stopped. A braking system comprises several components such as a brake pedal, rotor, caliper, brake pad, etc.

16. 10. Catalytic Converter A catalytic converter is a component that is part of the vehicle's exhaust system.  Its primary role is to reduce the oxides of Nitrogen and/or hydrocarbon and carbon monoxide in the emission gases. It helps remove toxic elements from the exhaust gases before emitting them through the exhaust pipe. During combustion, harmful gases emitted by the engine include hydrocarbons, carbon monoxide, and nitrous oxide. 11. Muffler A muffler is a part of the exhaust system and helps muffle noise coming from the exhaust system. It's located just before the exhaust pipe. It is made of aluminum coated steel to protect it from heat and chemicals emitted from the exhaust system. It reduces exhaust noise by restricting the flow of exhaust gases. Mufflers are also known as silencers. 12. Fuel Tank As the name suggests, the fuel tank holds the car's fuel (petrol/diesel). Generally, it's located before the rear axle.
