Ever wondered how a car engine looks like? The hood of your car secures the main machine, and the jumble of wires with metal can be overwhelming, especially for the uninitiated. However, the engine is the reason why your car can be driven around, and it is great to have knowledge about the car engines.

A car cannot run without a battery. A battery is a rechargeable element which supplies electrical energy to the car. Its main purpose is to start the engine. While the engine is running, most of the power is provided by the alternator, which includes a voltage regulator. Its also called an SLI battery which means starting-lighting-ignition.
