The automobile, sometimes known as a car or motorcar, is one of the world’s most universally recognized and widely used modern technologies. It is a wheeled passenger vehicle for transportation on land that uses an internal combustion engine, typically fueled with gasoline, but also diesel fuel, wood gas, and liquid petroleum gas (LPG). The branches of engineering that deal with the manufacture and technology of automobiles are called automotive engineering.
OVERVIEW
Automobiles make people’s lives easier in many ways. They can be a lifeline in emergency situations when someone falls sick or when an unexpected problem arises at work. They allow people to travel longer distances, expanding their horizons and giving them more options for their work location or leisure activities. They can also be a great source of pollution and are a threat to wildlife, causing acid rain and other environmental problems.
Today, the car is the main form of transportation in most countries. Its popularity has led to a growth in industries and jobs associated with cars, such as the manufacturing of parts and components, as well as the creation of services like gas stations.
Thousands of different kinds of parts go into making up an automobile. These can range from small components to large cylinders and pistons. They are arranged into semi-independent systems, such as the circulatory system that circulates fuel, coolant fluid and lubricating oil. The heart of a modern automobile is its engine, which can produce power ranging from under fifty to over 200 horsepower in large commercial vehicles.
