Automobiles are large land vehicles with four wheels and a motor or engine to make them move. They are used to transport people from one place to another and can be a very useful alternative to public transportation.
OPENS UP THE WORLD
An automobile allows you to travel in comfort and style, and gives you the opportunity to live a life with more options for work, social circles, and housing choices. It also saves you a lot of time on your daily commute, shopping trips, and visits to family and friends.
The modern automobile is a complex technical system employing thousands of subsystems with specific design functions. Many of these systems are designed to interact with and support each other.
The engine, which powers the car’s motion, is a series of moving parts that need to be protected from heat and friction. This is achieved by using a lubrication system that circulates oil between the moving parts and prevents them from touching. The system also helps reduce wear by carrying off heat that might otherwise cause the engine to fail.
The gasoline or diesel used in an automobile’s internal-combustion engine is volatile and must be carefully regulated to avoid overheating or damage. It must also be stored and disposed of properly to prevent pollution and a dangerous buildup of exhaust gases.
The suspension system of an automobile helps to absorb vibrations and shocks that are caused by road surfaces and changes in the vehicle’s weight. It also provides the body with a rigid foundation for the passengers and structural support for the wheels and tires.
