An automotive starter is an electric motor that initiates the engine's operation in vehicles. When the driver turns the ignition key or presses the start button, the starter engages and spins the engine's flywheel, allowing the engine to begin its combustion process. This component is essential for starting both gasoline and diesel engines. Typically powered by the vehicle's battery, automotive starters are designed to withstand high temperatures and vibrations. They consist of several parts, including a solenoid, which acts as a switch to control the flow of electricity, and a pinion gear that engages with the engine's flywheel. Proper maintenance of the starter can enhance a vehicle's reliability.
