Few inventions in modern times have had as great an impact on human society as the automobile. Whether it’s your daily commute or a trip to the store, having your own vehicle can save you time, money, and frustration. It also gives you freedom to visit friends and family or pursue other interests without having to wait for the bus or your ride home.
The first cars were steam and electric powered, but it was not until 1885 that Karl Benz built and patented the first gas powered automobile. Since then, hundreds of different car models have been produced. Regardless of the model you choose, all automobiles are designed with many factors in mind to ensure safety and performance.
The engine is the heart of every automobile. Its job is to transform the gasoline (or diesel fuel) into the power that drives the wheels. Automobile engines can have from four to eight cylinders that work in tandem to turn the crankshaft. The more cylinders the engine has, the more power it can produce.
The lubrication system of an automobile is vital for the health of its engine. Without it, the rapid movement of the metal parts would quickly cause them to wear out and fail. The lubrication system carries oil from the crankcase through a series of passages and holes to all of the engine’s moving parts. The oil forms a thin layer between the moving parts and reduces friction by carrying off heat.
