Automobiles are a crucial part of modern life. Without cars, it would be almost impossible to get around. They allow us to commute quickly and efficiently, shop for things we need, visit family and friends, and take care of business. They can also be used in emergencies to get people from one place to another, such as when someone is ill or injured. This is why it is important to have your car regularly serviced.
The branch of engineering which deals with the manufacture and technology of automobile vehicles is known as Automobiles Engineering. Today, the car plays a major role in our daily lives; it acts as a lifeline for humans.
An automobile is a four-wheeled, self-propelled vehicle for passenger transportation, designed primarily to be driven on roads. It is usually powered by an internal combustion engine using a volatile fuel, such as gasoline or diesel fuel. Other sources of power for an automobile include electricity and natural gas. Some early automobiles used steam engines attached to wagons, but these were heavy and slow. In the late 1880s, Edouard Delamare-Deboutteville and Leon Malandin of France built and patented a vehicle with an internal combustion engine on a tricycle. However, during the first test drive, the tank hose came loose and caused an explosion.
The speed of an automobile depends on the size and power of its engine, as well as the ratios of its transmission system. The gears allow for a considerable ‘leverage’ between the torque produced by the engine and the speed of the road wheels.
