In front wheel drive vehicles, it s necessary to transmit power to the front wheels as they are turned from side to side by the steering mechanism. Also, as the vehicle makes turns, the wheels on either side must turn at different speeds while still transmitting power. CV joints are the mechanical couplings that allow this to happen. The boots are accordion-like pleated, rubber covers that prevent the CV joints from being exposed to weather and keep them lubricated. The engine s powerful explosions take place at the top of the cylinder.
Engines typically have from four to eight cylinders.
It s driven by a shaft from the engine and is essentially a rotating switch. The rotor is the part of the distributor that revolves to sequentially make contact with each spark plug, and the cap is the part of the distributor that holds those contacts. The components that cause the wheels to turn. Some people would include the engine itself in this definition. The sheet metal barrier between the engine compartment and the passenger compartment.
