Automobiles and Motorcycles
Automobiles are technically complex systems, consisting of thousands of components. The components of an automobile include wheels, axles, body, frame, suspension system, engine, and transmission system.
Modern automobiles have undergone tremendous technological changes. For instance, the use of aluminum engines has helped improve stability. Additionally, emission-control systems and other safety measures have been improved.
Historically, cars were bicycle-like contraptions. During the early nineteenth century, inventors such as Edward Butler and Sylvester Howard Roper developed pedal cycles that were later converted to motorcycles.
After World War II, the auto industry saw an increase in production. Automakers were able to split the market into smaller segments.
Cars are the most common form of transportation in today’s society. They carry passengers and goods and have become a critical part of the global economy. However, automobiles are still not a perfect solution to all needs.
In the United States, the definition of an automobile is usually defined as a four-wheeled vehicle that is propelled by an internal combustion engine. Vehicles are categorized by size, speed, and capacity.
Vehicles designed for off-road use have different requirements. They need to be durable, reliable, and resistant to extreme operating conditions. They also need to be able to withstand extreme overloads.
An automobile is an expensive machine. Therefore, the manufacturers are constantly improving its drivetrain, control system, and safety features. Also, automobiles are being manufactured with more industrial materials.
As of 2010, the U.S. Environmental Protection Agency had set limits on hydrocarbon emissions. New motorcycles were only allowed to emit 1.4 grams of hydrocarbons and nitric oxides per km. Meanwhile, the European Union imposed stricter limits on the amount of carbon monoxide in new motorcycles.
