Automobiles are wheeled vehicles that are used for transportation. Most definitions state that they run on roads and seat one to eight people. They also say that their primary purpose is to transport people. There are many types of cars on the market today. Learn about the different types of cars in this article. And learn about their safety features.
Internal combustion engines
The internal combustion engine is an internal combustion engine which burns fuel in an internal combustion chamber. It was first developed during the early sixteenth century and was based on a principle which was originally used for drawing water. The principle involved the explosion of gunpowder in a closed chamber which created a vacuum and a movement in a piston by external atmospheric pressure.
Transmissions
A car’s transmission transfers power from the engine to the wheels. It uses different types of gears to vary the amount of torque and speed needed to move the car. A manual transmission uses a single belt to transfer power to the wheels, while an automatic transmission uses a combination of different gears.
Seating capacity
Seating capacity in automobiles varies based on their size, and can range from just one person to more than ten. The most common seating capacity is five people, and sedans and hatchbacks are typically sold with this number of seats.
Safety
The improvement in crash safety of automobiles has been proven through case and macrostatistic analyses. This is because car designs are manufactured with a crush zone that absorbs the impact from an impact. This deformation reduces shock and protects the occupants during a collision. However, the amount of deformation varies with the pre-collision energy of each vehicle.
Cost
The cost of an automobile is the sum of all the internal costs that a consumer pays to own one. These costs are normally divided into two types: fixed and variable costs.
Environmental impact
The automotive industry is a major contributor to the US economy, providing 6.6 million jobs in sales, manufacturing, and services. But many people may not realize that the automobiles we use every day have a significant impact on the environment. Vehicles often contain toxic chemicals such as lead and mercury, which remain in the environment and can accumulate in the food chain. In addition, 12 million used cars are discarded each year in the US and Canada. As a result, the production of new automobiles consumes vast amounts of non-renewable resources.
