käivitajast

A käivitaja, often translated as starter or igniter, is a crucial component in many systems that require an initial impulse to begin operation. In the context of internal combustion engines, a käivitaja is an electric motor that cranks the engine, rotating it until it can sustain its own combustion cycle. This electric motor draws power from the vehicle's battery and engages with the engine's flywheel or flexplate to initiate the turning motion. Once the engine starts, a mechanism disengages the käivitaja to prevent damage.

Beyond engines, the term käivitaja can refer to devices that initiate other processes. For instance, in electrical systems, a käivitaja might be a component that initiates a controlled flow of current to power up a larger circuit. In lighting, a käivitaja, specifically a glow starter, is used in fluorescent lamps to provide the initial high voltage needed to ionize the gas within the tube, allowing current to flow and produce light. The specific design and function of a käivitaja are highly dependent on the system it serves, but its core purpose remains the same: to provide the necessary initial energy or action for a process to begin.
