14. Fuel Tank:-

A Fuel tank is a part of the engine system which is utilized to store flammable fluids and release them into an engine. It is for the most part located under the middle segment of the car. This tank can be filled from an external perspective through a small hole that is covered with a gas cap when not being used.

15. Seat belt:-

A seat belt is a safety gadget, a belt that is designed to secure any occupant of the vehicle against undesirable movements that might be caused during a collision. It assists with keeping the occupants positioned securely and prevents the traveler from being thrown away from the vehicle on impact.

16. Shock Absorbers:-

 The suspension is comprised of many parts, and the shock absorbers are a significant part of this system. Shock absorbers assist with keeping your car consistent while you’re driving. The primary job of the shock absorbers is to ensure that your tires generally touch the road.

17. Steering System:-

The steering system is utilized to turn the car in somewhere at a different position. The main thing about a steering system is that it is precise and simple to utilize and that the front wheels will generally return to confronting straight ahead after a turn. The steering system makes it conceivable to steer the car or turn it to the left or right.

18. Lubrication System:-

Moving parts or components develop wear ultimately as they move along one another. A lubricant is circulated between these moving parts so the parts move over one another with minimal friction. This aids in diminishing the power loss because of friction. The lubricants likewise go about as a coolant themselves. These are exceptionally viscous fuels that are suited to work at high temperatures and pressure.

19. Cooling System:-

The cooling system is designed with the end goal that the engine neither overheats nor overcooks.
