An automobile, byname auto, or motor car is a four-wheeled vehicle that’s designed primarily for passenger transportation. It’s propelled by an internal-combustion engine that burns a volatile fuel. The modern automobile is a complex technical system with thousands of component parts. Each part has a specific design function and contributes to the overall performance of the automobile.
Automobiles are a great convenience that allow us to take our families where we want, when we want. However, they can also be a source of frustration, especially when they aren’t maintained properly or driven responsibly. Here are a few tips to help you get the most out of your automobile and make it a joy to own.
The most important systems in an automobile are the engine, transmission, electrical system, cooling and lubrication system, and chassis. The chassis is the base on which other parts are attached, including the suspension system, braking system, wheels and tires, and body. The body is made of sheet metal welded to the chassis, which offers passenger protection and provides storage space. The body is often made of steel, but aluminum and plastic are also used.
The lubrication system of an automobile reduces the friction between moving parts and carries off heat. The oil reservoir is in the crankcase, and a pump, powered by the engine, moves oil through a series of passages and holes to the moving parts. The heated oil cools, reducing the wear and tear on the engine’s components.
