Automobiles are a means of transportation that allows you to move about more quickly than walking or using public transit. An automobile lets you spend less time moving from place to place, so you can have more time to relax or focus on other tasks. In addition, a car allows you to take your family or friends on outings and make visits that you wouldn’t be able to otherwise make.
The automobile has many different systems, including those for powering the engine, braking, steering, and suspension. It also has a control system that uses computer technology. The design and arrangement of these systems are influenced by several factors, including the type of automobile and its intended use. For example, a passenger car that is designed for long trips will be larger than a sports car that is designed for high speed driving. The choice of front- or rear-wheel drive can affect the automobile’s handling and fuel efficiency, as will the type of suspension.
An important feature of an automobile is its lubrication system, which reduces friction between metal parts and carries off heat from them. The oil is stored in a crankcase, and a pump, powered by the engine, carries it through a series of passages and holes to all the parts of the motor. Then, as the oil cools, it drains back into the crankcase.
The chassis and body of an automobile, analogous to the skeleton of a human body, support the various systems and protect passengers from the elements. They must be strong enough to withstand the force of an accident, and they must also offer safety features.
