Understanding how individual parts of a car work is the key to understanding how the entire automobile works. A differential is a part of the engine. It is the three-shafted gear train that splits the engine torque in enough ways to make it possible to adjust the car's speed safely while turning.
It is important to understand that not every car has a differential. Part-time four-wheel drive systems do not have one; instead, they are locked together. With a differential, the front wheels and the back wheels can move separately from one another, making it easier for the car to get around on different types of surfaces.
