Automobiles are vehicles that use a motor to propel them forward. The motor may be powered by gasoline, electricity or another fuel such as kerosene or diesel oil. The automobile has become the principal means of transport worldwide. It has changed the way people live, work and play. It has brought about new jobs, leisure activities, housing and services such as motels and hotels. It has also caused problems such as traffic congestion, air pollution and the loss of undeveloped land used for roads and parking lots.
The history of the automobile began in the 1600s when a Dutch scientist named Christiaan Huygens invented a type of internal combustion engine fueled by gunpowder. However, the modern car wasn’t developed until the 19th century when steam and electric cars made their debuts. Gasoline was introduced in the United States as a motor fuel in the 1920s.
Pros: The automobile allows people to travel long distances with ease. This opens up a wide variety of job opportunities and allows people to include more people in their social circle. It has also allowed people to move to places that are farther away from where they were born and raised and enjoy a variety of different climates and scenery. Cons: An automobile can be expensive to operate and maintain. It also has a negative effect on the environment due to its emission of carbon dioxide, which is a greenhouse gas. There are ways to lessen the environmental impact of an automobile, such as using fuel-efficient models and maintaining them properly.
An automobile is a four-wheeled vehicle designed primarily for passenger transportation. It is usually propelled by an internal combustion engine powered by a volatile fuel such as gasoline, diesel or kerosene. The engine is a complex technical system involving thousands of component parts with specific design functions. The engine is a major part of an automobile and determines its working capability. The engine can be a spark ignition or compression ignition engine, or it can be an electrically driven engine with an external gearbox.
Automobiles can be divided into three categories based on their purpose; passenger vehicles, commercial vehicles and special purpose vehicles such as ambulances and fire brigade vehicles. Passenger vehicles include cars, buses and taxis. Commercial vehicles are trucks and tempos, while special-purpose vehicles include ambulances, fire engines and police vehicles. In many countries, automobile production is a multinational industry, with several manufacturers competing in the market for customers. For example, in the United States, Ford and Chrysler produce vehicles for domestic as well as foreign markets. In some countries, such as China, local manufacturers dominate the automobile industry. In other countries, such as Russia, the state-owned AvtoVAZ company has produced a number of models of automobiles that haven’t undergone major redesign since they were first marketed. Examples are the VAZ-2101 (1200 sedan), the VAZ-2102 (estate) and the VAZ-2106 (4-door). Subaru’s compact SUV, the Forester, is an example of an automobile that has undergone only minor mechanical revisions over the years.
