käivitusmehhanism

A käivitusmehhanism, or starting mechanism, is a component or system that initiates the operation of an engine or other machinery. Its primary function is to overcome the inertia of stationary parts and bring them up to a speed where the engine's own power can sustain operation.

Various types of käivitusmehhanism exist, depending on the application. For internal combustion engines, common examples include electric starters, which use an electric motor to turn the crankshaft, and manual starters, such as pull cords or hand cranks, which require human effort. In some larger engines, pneumatic or hydraulic starters might be employed, utilizing compressed air or fluid pressure to engage the engine.

The process typically involves a drive mechanism that engages with a flywheel or a similar rotating component of the main engine. Once the engine reaches its self-sustaining speed, the käivitusmehhanism disengages to prevent damage. The design and complexity of a käivitusmehhanism are determined by factors like engine size, power output, and the operating environment. Reliability and efficiency are key considerations in the development and selection of a suitable käivitusmehhanism.
