Automobiles are a kind of vehicles which are used for transportation. They are mainly propelled by an internal combustion engine which burns a volatile fuel like petrol or diesel.
Depending on the purpose of use, automobiles are classified into different categories such as passenger vehicles, trucks, vans, buses, and so on. The body of an automobile is made from a steel or aluminum alloy.
A car has an engine in its front or rear side. The front or mid-engine is most common and is weighted at the front or behind the front axle.
Another important part of an automobile is a transmission, which is a system that converts the power from an engine into motion to the wheels. The transmission has many gears that allow the vehicle to be driven faster or slower.
The transmission also has a device called a clutch, which is used to connect and disconnect the engine from the transmission. The clutch allows the load to take off slowly, thereby preventing jerky movements and avoiding undue stress on the vehicle as well as the passengers.
Automakers are always striving to make their vehicles safer. They are working on new technologies to improve safety systems, including tire pressure monitoring and stability control.
People also want cars to be more environmentally friendly. Most cars run on gasoline, which releases carbon dioxide into the atmosphere. This release of gas can be controlled by limiting the amount of gas that the driver uses.
