Engine Starter Unit

An Engine Starter Unit, also known as a starter motor or starter, is an electrical device used to start an internal combustion engine. It is typically a small, high-torque motor that is connected to the engine's flywheel or flexplate.

When the ignition key is turned, the starter motor is activated and it engages with the flywheel or flexplate, causing the engine to crank and start running. The starter motor uses electrical power from the vehicle's battery to generate the necessary torque to turn the engine over.

The starter motor is designed to provide a high amount of torque for a short period of time, as starting an engine requires a significant amount of power. Once the engine is running, the starter motor disengages from the flywheel or flexplate.

In addition to starting the engine, some starter motors also have other functions, such as engaging the engine's timing gears or controlling the fuel injection system.

Overall, the engine starter unit plays a crucial role in the starting process of an internal combustion engine, ensuring that the engine starts smoothly and efficiently.
