Automobile - Structure Of The Automobile

Thousands of individual parts make up the modern automobile. Much like the human body, these parts are arranged into several semi-independent systems, each with a different function. For example, the human circulatory system comprises the heart, blood vessels, and blood. The automobile contains analogous circulatory systems for coolant fluid (mostly water), for lubricating oil, and for fuel. The engine—the "heart" of the automobile—is comprised of pistons, cylinders, tubes to deliver fuel to the cylinders, and other components. Each system is necessary for making the automobile run and reducing noise and pollution.

The major systems of an automobile are the engine, fuel system, transmission, electrical system, cooling and lubrication system, and the chassis, which includes the suspension system, braking system, wheels and tires, and the body. These systems will be found in every form of motor vehicle and are designed to interact with and support each other.
