Käivitusmootoris

Käivitusmootoris refers to the starter motor in Estonian. It is an essential component of an internal combustion engine, responsible for initiating the engine's rotation to start the combustion process. The starter motor is an electric motor that draws power from the vehicle's battery. When the ignition is turned, a solenoid engages a small pinion gear on the starter motor with a larger gear, typically the flywheel or flexplate, connected to the engine's crankshaft. The electric motor then spins the pinion gear, which in turn rotates the crankshaft. This rotation allows the engine's pistons to move, drawing in fuel and air, compressing it, and igniting it, thereby starting the engine's self-sustaining operation. Once the engine starts and reaches a certain speed, the solenoid disengages the pinion gear, and the starter motor stops. Starter motors are designed for short bursts of high torque to overcome the initial inertia of the engine.
